Contraceptive Ring Reminder +
A single skilled developer can build a minimal ring‑reminder app and widget, but reproducing the full App Store product (polish, Store presence, active user base, and paid subscription flows with reliability) is multi‑week and nontrivial; a narrow replacement (local reminders + calendar) is realistic.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User sets ring-in duration → app schedules local reminders → user marks insert/remove in calendar → app shows cycle overview and countdown → optional iCloud backup of user data
What it still won’t have
- App Store listing history, ratings and reviews
- Established user base and brand trust
- Polished design and bug‑fix release cadence shown in version history
- Developer support channel (support@cauim.co) and active updates
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build an iOS app (Swift + SwiftUI) that schedules local reminders for contraceptive ring insert/remove events, includes a calendar view with per-day notes and CRUD for events, a small widget showing next action/countdown, local data persisted in Core Data with optional iCloud sync, and StoreKit-based subscription to remove ads and unlock advanced notification settings. Out of scope: server backend (keep data iCloud-only), analytics and ads mediation. Deliver: unit tests for scheduling and data model, error handling for iCloud sync failures, and CI job to build app and widget.
How we checked
How the score was reached
- Partly verdict base52
- 3/3 assessment runs agreed+4
- Evidence score56
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
