Captime
A single competent iOS developer can reproduce the core timer, voice controls and video overlay in a few weeks; no durable moats block a rebuild and an open-source HIIT timer exists as 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 Captime alternatives, with the arithmetic →
What a replacement has to do
- Create and run interval workouts (AMRAP, EMOM, Tabata, Intervals) with large readable timer, optional video overlay, voice-start, and automatic audio ducking.
What it still won’t have
- App Store distribution, reviews and discoverability
- Polish, localization and multi-device UI refinements present in the shipped app
- Ongoing crash-reporting/analytics pipeline unless added
- Developer support and bugfix cadence from the vendor
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 implements a HIIT/WOD timer. Core features in scope: precise timer engine (AMRAP, EMOM, Tabata, custom intervals); fullscreen large-digit timer UI; voice 'START' command via Speech framework; audio ducking during beeps; simple video recording mode that overlays the running timer on camera capture; App Store-compatible in-app subscription flow and local persistence of workouts. Out of scope: backend server, user accounts, analytics dashboards, social sharing. Deliverables must include error handling, unit tests for timer logic, and CI build configuration to produce an App Store archive.

- Evidence score65
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.
