01Repair Part Test-Fit AppProduct HuntThis iPad modeling app is for people repairing furniture, housings, or small-appliance parts. It starts with a scan of the connection area and generates an adjustable mating part. Users capture a pass around a break or gap, and the first screen immediately highlights places where the part will not insert, may wobble, or lacks wall thickness. They can then drag clearance, clip depth, and screw holes with a finger while cross-sections change color in real time, without first learning a full CAD command set. The app can also generate versions for different print materials; after a test print, users record “too tight” or “too loose,” and the next version converges from that feedback. Rather than creating parts from a blank canvas, it handles scanning, fit assessment, and test-fit iteration around a real interface.View detailsHide details
Helps repairers scan a break or interface, adjust fit clearance on an iPad, and export a part model for test fitting.

Rather than creating parts from a blank canvas, it handles scanning, fit assessment, and test-fit iteration around a real interface.
Who it is for
Repairers, makers, and small repair shops with a home 3D printer or access to printing services. They use it when an original part is unavailable, a housing has broken, or an existing model does not fit, and they want a test-fit part quickly rather than a general CAD learning curve.
Smallest useful version
Start with imported or captured STL and OBJ scan meshes only. Let users mark a connection area, adjust uniform clearance and wall thickness, and export a printable STL. Do not build full CAD, automatic clip generation, or material simulation yet.
Why now
PixyCAD launched on Product Hunt on July 16, 2026. As of July 18, 2026, 00:33 UTC, it ranked #4, and the product already combines native iPad solid modeling, Apple Pencil input, and print-format export in one workflow. This means that scanning a real interface, directly adjusting fit, and test fitting can build on an iPad modeling and 3D-printing workflow users already understand. This is a timely moment to test demand through a repair-specific entry point.
Strongest counterargument
The strongest case against this is that breaks, hole locations, and thin-wall structures are highly sensitive to dimensional error. Meshes from ordinary iPad captures may not be accurate enough, so users may still need caliper measurements and manual reconstruction of critical dimensions.
PixyCAD - Powerful 3D CAD, Beautifully Simple — Supports that PixyCAD runs natively on iPadOS and macOS, uses Apple Pencil, models on-device, and exports STL, 3MF, STEP, and Parasolid X_T.
Reverse Engineering an STL File — Supports Shapr3D’s existing reverse-modeling workflow that starts from STL meshes to build housings, mating edges, and mounting posts for electronic components.
What File Types Can Polycam Export? — Supports that Polycam can export mesh formats including OBJ and STL from iPad scans, while explicitly not supporting STEP export.
02Tonight’s stargazing windowScienceHelps people who decide at the last minute to watch meteors find the short windows from their current location that are actually worth looking up for. Standing on a balcony, in a yard, or at a campsite, users rotate their phone to scan the horizon; the app combines obstructions from buildings and trees, cloud cover, moonlight, and the meteor radiant, then shows the best 20 minutes, direction, and a visibility score on the first screen. If conditions are poor tonight, it clearly says "not worth waiting now" and compares nearby observing spots that users can reach and return from within their free time. Before the window begins, the screen switches to a dim guide that retains only the direction, countdown, and light sources to avoid. Rather than publishing one stargazing forecast for an entire city, it recalculates whether the user can see anything using the actual horizon in front of them.View detailsHide details

Rather than publishing one stargazing forecast for an entire city, it recalculates whether the user can see anything using the actual horizon in front of them.
Who it is for
People who decide at the last minute to watch meteors but will not stay up for a vague forecast. They open it after dinner, at a campsite, or before driving out to quickly decide whether to wait, where to look, or whether to change locations.
Smallest useful version
Start by assessing whether the user’s current location has a worthwhile 20-minute window tonight: have users manually trace the obstruction profile along the real horizon, use Open-Meteo cloud-cover forecasts and Astronomy Engine moon positions, then combine them with a public meteor-shower calendar to show the time, direction, and "worth waiting / not worth waiting".
Why now
The 2026 Perseid meteor shower entered its active period on July 17; as of July 18, 2026, 00:33 UTC, "perseid meteor shower tonight" remained an active search in the United States, with about 2,000+ searches in the past 168 hours and a recorded increase of about 200%. The concentrated search for "can I see it tonight?" and the period leading to the August 12 to 13 new-moon peak night make this a suitable time to meet demand with an immediate assessment based on the user’s location and actual obstructions.
Strongest counterargument
The strongest case against this is that phone compass errors, changing local cloud cover, and incomplete obstruction scans could make a seemingly precise 20-minute score create false confidence.

03Post-Earthquake Family Roll CallClimatePost-Earthquake Family Roll Call is a mobile app for families to confirm safety and decide where to meet after an earthquake. Family members register regular locations such as school, home, and work in advance. After an earthquake, the first screen ranks the people to confirm first by shaking intensity, tsunami zone, and last known location. Each person can report safe, injured, or trapped with one tap, or send a minimal status packet by SMS on weak networks. If the planned meeting point falls within a tsunami zone or an area with blocked roads, the app suggests alternative locations that everyone may still be able to reach. Rather than piling up "where are you" messages like a group chat, it continuously consolidates unconfirmed members and the next meeting decision.View detailsHide details

Rather than piling up "where are you" messages like a group chat, it continuously consolidates unconfirmed members and the next meeting decision.
Who it is for
People in earthquake- or tsunami-risk areas whose family members are spread across school, home, and work during the day. They open it after a major earthquake, when communications are disrupted and they need to quickly identify who has not checked in and where to meet.
Smallest useful version
Start with family and regular-location setup, a three-status post-earthquake roll call, an unconfirmed list, and SMS fallback. Use USGS earthquake data, Twilio for SMS, and OpenStreetMap for maps and place data.
Why now
On July 17, 2026, a 7.3-magnitude earthquake struck offshore from Chiapas, Mexico. Shaking extended from Mexico City to El Salvador, and coastal tsunami risk had to be assessed for a time. Searches for "mexico earthquake" in the United States reached about 100000+ over the past 168 hours, up about 900%, and remained active as of July 18, 2026, 00:33 UTC. This indicates that many families are currently seeking post-earthquake information, making this a timely moment to consolidate scattered safety messages into a clear roll-call and meeting process.
Strongest counterargument
The strongest case against this is that post-earthquake location, road, and communications data are often incomplete. If the app gives a seemingly certain but outdated meeting recommendation, it could be more dangerous than a simple plan agreed by the family in advance.
Signal, observation time, and sources

04All-Group Theme Park PlannerOtherThis mobile app for families and groups of friends turns each person’s height, thrill tolerance, and mobility constraints into a map of what the group can do that day. Before entering the park, the first screen sorts rides into "everyone rides together," "needs a rotation," and "not recommended," and shows who is constrained. Opening a roller coaster directly assigns who rides first, who watches the children, where to meet, and what those waiting can do nearby. If a ride closes or someone no longer wants to queue, it rearranges the remaining order around the group’s must-do rides. Standard park maps list individual height requirements and wait times; this handles the recurring group-splitting, rotation, and fairness problems that arise when people visit together.View detailsHide details
Helps groups plan shared rides, rotations, and lower-wait park itineraries from each person’s height, thrill tolerance, and must-do rides.

Standard park maps list individual height requirements and wait times; this handles the recurring group-splitting, rotation, and fairness problems that arise when people visit together.
Who it is for
Families and groups with children, older adults, or people who do not want high-thrill rides. They use it before entry to assign must-do rides, then reopen it for closures, people leaving queues, or Rider Swap needs.
Smallest useful version
Launch with Cedar Point only. Use the official park guide to capture height, companion, and mobility constraints, then let users select members and must-do rides to generate the three groups and a static order. Handle disruptions through manual ride closures and one-click replanning, without relying on an unconfirmed real-time API.
Why now
On July 16, 2026, Cedar Point announced it would close early at 19:00 that evening because of air-quality issues caused by Canadian wildfires. During the same period, Google Trending Now recorded approximately 10000+ searches for "cedar point" over the past 168 hours, up 100%, but interest had fallen by the observation time of July 18, 2026, 00:33 UTC; the trend ended on July 17 at 18:10 UTC. The concentrated search occurred as visitors' plans were disrupted, making "quickly reorder the day’s plan around the whole group’s constraints" a use case users can understand without education.
Strongest counterargument
The strongest case against this is that if ride closures and wait times rely on manual user updates, dynamic replanning will likely lag behind the official app, making the core experience hard to trust.

05Moving Trial BudgetOtherMoving Trial Budget is a web app for people preparing to move that uses real spending records to simulate one month of life in another city. Users import bills from the past month and select a target ZIP code. Instead of showing an average index on the first screen, it shows the monthly difference after recalculating line items for housing, commuting, food, insurance, and more. When an exact equivalent merchant or service cannot be found, it lists alternatives and makes clear which differences come from price, distance, or unavoidable lifestyle changes. Users can also switch homes or commuting modes to see which adjustment most reduces the budget gap. Standard city comparisons put everyone into the same consumption basket; this replays a month the user has actually lived.View detailsHide details

Who it is for
People comparing job offers, rental locations, or cross-city moves. They open it after getting a target address, rent, or commute location and want to know how much their own lifestyle would cost there.
Smallest useful version
Start with bill CSV uploads, categorize housing, food, and commuting items, and recalculate them for the target location. Use the Numbeo Cost of Living API for local prices and the Google Maps Platform Routes API for commuting distance and time; ask users to confirm unmatched substitutes.
Why now
Google Trending Now recorded approximately 200+ searches for "cost of living" in the United States, with 100% growth; the spike ended on July 17, 2026, at 11:20 UTC, and had receded by the observation on July 18, 2026, at 00:33 UTC. Concentrated searches over a short period suggest that movers still actively seek cost-of-living answers at specific decision points. Bringing personal bills into a target location can answer this question more directly than a city-average index.
Strongest counterargument
The strongest case against this is that it is difficult to find strict equivalents for bill items, merchants, and insurance plans in another city. Without transparent reasoning behind substitute matches, the result may look precise but not credible.

06Difficult Stage Failure ReplayGamesMobile-game players can give a phone app a recording of a difficult stage and a screenshot of their team to pinpoint where the attempt actually began to fall apart. After a loss, they import the video and see a battle timeline instead of a generic character ranking, marked with the first irreversible mistake, the mechanic it triggered, and an alternative action that was possible at that moment. Using the player’s existing characters, the app assigns just one key change for the next attempt, such as changing entry order, saving a skill, or replacing one position. After another recording, it aligns the two runs at the same mechanic checkpoints so players can see whether the change actually extended the effective damage phase. It turns guides from copying a recommended team into iterative corrections based on the player’s own play.View detailsHide details

Who it is for
Mobile-game players repeatedly attempting Super Ultimate, Blast Ultimate, and similar difficult stages, but only able to conclude that damage was too low or the route was wrong. They open it just after failing, when they are adjusting their team and about to start another run.
Smallest useful version
Start with Higuruma Hiromi Super Ultimate in Monster Strike. After players upload a recording and team screenshot, use FFmpeg frame extraction and OpenCV matching for fixed UI and mechanic prompts; manually curated stage rules then identify the earliest fatal checkpoint and output one change for the next run. Do not promise cross-game recognition or real-time overlays yet.
Why now
Monster Strike opened the Higuruma Hiromi Super Ultimate stage on July 16, 2026, and the event runs through August 2. In Google’s 168-hour Trending Now window in Japan, related guide terms recorded about "20,000+" searches and roughly 1,000% growth, and remained active as of July 18, 2026, 00:33 UTC. Many players are encountering the same new mechanics at once, so a single change for the next attempt based on a specific failed run fits their immediate review needs better than another generic team-ranking list.
Strongest counterargument
The strongest case against this is that mobile-game recordings may not include RNG, hidden states, or complete damage calculations, while stage rules can change with updates. If it identifies the first fatal checkpoint incorrectly, players will quickly lose trust.
コラボイベント第3弾が7/14より開催! — Supports that the third Jujutsu Kaisen collaboration began on July 14, and that the Higuruma Hiromi Super Ultimate stage opened on July 16 and runs through August 2.
Connects calendars and to-do lists, then shows only the current next step on the lock screen, with buttons to start, postpone, or switch tasks.People who often pick up their phone to check their schedule connect their calendar and to-do list. The lock screen then keeps only the most suitable next step and the time it needs. Starting, postponing, or getting stuck immediately advances, reschedules, or switches to an unblocked task.
Thunderstorm Departure Clock
Climate
Helps people heading out find the latest time to leave before a thunderstorm and where to take shelter.When commuting or taking children out, users enter their current location, destination, and travel mode. The page directly shows how long they can still leave safely before a thunderstorm. Once the window closes, it instead lists shelter buildings within walking distance and route segments that would still leave them exposed outdoors.
Prescription Out-of-Pocket Route
Health
Compares the current out-of-pocket cost, refill cost, and required steps across prescription purchase channels based on a patient’s prescription and insurance details.People on long-term medications enter a drug name, dosage, ZIP code, and insurance details to compare out-of-pocket costs for a course of treatment across insurance, cash prices, coupons, or direct-purchase options. Each route also shows refill costs, pickup requirements, and the steps required before switching channels.
Helps teachers replay whiteboard strokes, see the exact moment students first lose the thread, and add targeted explanations.Teachers preserve the order in which each whiteboard stroke appears. In the replay, students mark the first board state they can no longer follow. After class, the whiteboard groups confusion points by moment, and teachers can branch from that state into an explanation, add drawings, and send it to students.
Lets family members remotely take over complex portal tasks while sensitive login and confirmation steps remain on the person’s device.When helping parents remotely with insurance, bills, or public services, the extension splits the flow into pages a family member can take over and pages the person must complete themselves. Sensitive logins, verification codes, and signatures stay on the original device, while both people can always see the task status and the remaining steps for the person.
Filters candidate products based on real complaints that match a shopper’s non-negotiable issues.Shoppers open candidate product pages and first write down issues they cannot accept, such as noise or after-sales terms. The extension finds real complaints in discussions and reviews that are serious enough to rule out an option, and notes the context, purchased version, and whether the issue was later resolved.
Secondhand Jewelry Inspection
Shopping
Helps secondhand buyers photograph jewelry details and enter the asking price to get inspection gaps, a purchase band, and a risk-capped maximum price on a mobile web page.At a flea market, photograph the ring face, hallmarks, and setting, then enter the asking price. The page uses the available evidence to place it in one of three bands: buy, gather more evidence, or send for inspection. With each additional photo, the maximum bid and next inspection step update based on the remaining uncertainty.
Helps patients with long-term follow-up photograph lab reports from different hospitals, standardize units, and distinguish real trends from changes in testing conventions.Patients who need long-term follow-up photograph lab reports from different hospitals. The app standardizes units for the same test while retaining the original values and reports. It distinguishes value trends from changes in reference ranges and testing methods, then adds persistently abnormal results to a question list for the next appointment.
Outage Scope Diagnosis
Technology
Helps users diagnose the scope of an outage through parallel cellular and local network tests, then tells them whether to troubleshoot, switch networks, or wait.When home internet goes down, users test their router, local connection, ISP line, and specified websites through both cellular data and the affected Wi-Fi. The page first identifies whether the issue is on one device, the home network, a regional service, or a single app, then leaves only the relevant next step.
Helps family members connect an open e-reader and create a simple reading interface around an older person’s vision and mobility limits.After connecting an open e-reader for an older family member, family members can configure fonts, page-turning methods, accidental-touch limits, and the book library, then simulate startup, finding a book, and resuming reading. The device keeps only essential entry points and syncs page numbers, the number of times the reader gets stuck, and markers for when help is needed.
