You are a senior product engineer. Turn the product idea below into a locally runnable MVP.

## Idea

To-do calendar scheduler
Turns Apple Reminders into calendar blocks automatically, reducing manual time planning.

## Product concept

A freelancer opens their Mac in the morning and sees client replies, invoicing, and revisions piled up in Reminders, with no clear sense of what to do first. The product reads Apple Reminders and Calendar, then turns tasks into calendar blocks based on deadlines, estimated duration, and free time; the user only needs to drag them into place and confirm. The focus is on what can be finished today, rather than building another to-do system.

## Why now (backed by facts)

PopTask reached No. 1 on Product Hunt on the day it launched with the idea of turning to-dos into scheduled tasks. This looks more like evidence of Apple users' frustration with the split between Reminders and Calendar: writing down the task is easy, while rearranging the day is the real burden.

## Direction (model inference, not independently verified)

Target user: Freelancers and small-team leads who mainly work on Mac and iPhone and manage their own delivery schedules.

Minimal entry point: Start with a Mac menu bar app that connects only to Apple Reminders and Calendar. Users enter an estimated duration for each task, and the app creates time blocks for today and writes them back to the calendar. It does not cover team collaboration, cross-platform sync, or long-term AI planning. It focuses on making today and tomorrow easy to schedule.

The strongest case against: The strongest case against this is that Product Hunt attention may only show that productivity-tool enthusiasts like the concept, not that small teams will change their existing calendar habits. The real challenge is whether users will keep maintaining task durations. If they do not want to enter them, automatic scheduling will quickly become another table that needs upkeep.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Build an interactive landing page around searches such as “Apple Reminders to calendar” and “Mac to-do automatic time blocking.” Publish in the Setapp user community, Mac Power Users, and freelancer productivity blogs. The tool also generates a “today’s schedule” image that users can easily share in workflow posts.

## Competitors & gaps (model inference)

- Apple Reminders: It records tasks but does not automatically turn them into calendar blocks based on free time.
- Motion: Its scheduling logic depends on a cloud account and taking over the full calendar, so it does not suit people who want to keep their data in Apple’s local apps.
- Reclaim.ai: It is designed around team calendars and cloud sync, making it a poor fit for local workflows that use only Apple Reminders and a personal calendar.

## How it makes money (model inference)

Users pay after sustained use to unlock automatic write-back to Apple Calendar, saved scheduling rules, and multi-day rolling schedules. A one-time purchase could also suit Mac users who do not want to give a cloud scheduling service access to their calendars.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
