reveille
A capable developer can build a useful subset (timed alarms, math/barcode/step missions and subscriptions) in a few weeks using iOS APIs; reproducing the app's advanced pose-detection, on-device ML and polished anti-cheat/analytics would be substantially harder and is not covered by available prior art.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All reveille alternatives, with the arithmetic →
What a replacement has to do
- User schedules alarms -> system fires local alarm notification -> app presents missions (math, barcode scan, step count) -> user completes missions -> app records completion and optionally re-checks
What it still won’t have
- Real-time camera-based push-up / pose-detection skeleton overlay (ML model + on-device inference)
- Advanced anti-cheat checks that re-verify physical state after mission completion with remote analytics
- Polished animations, localized content in 6 languages, and continued App Store polish and 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 a minimal iOS alarm app in Swift and SwiftUI with local-only alarms (UNUserNotificationCenter), mission screens (math and timed puzzles), barcode-scan mission (AVFoundation), step-count mission (HealthKit/CoreMotion), subscription handling (StoreKit), and local persistence (Core Data). Out of scope: on-device ML pose detection, server-side analytics, multi-user sync. Include background-safe alarm scheduling, reliable re-check logic after mission completion, error handling for permissions, unit tests for mission logic, and integration tests for alarm scheduling.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 3 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
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.
