Learning and careers decision
I Can Tell Time
A single developer can replicate the core lessons, local progress, and subscription flow, but reproducing the product’s decade of polish, App Store traction, COPPA-validated compliance and school licensing is costly, so rebuilding a useful subset is realistic while matching full product value is not.

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
- Present a short lesson (multiple-choice, drag-the-hand, listening), record completion and award stars/streaks, unlock next lesson or premium units via subscription, allow free-play clock with spoken feedback.
What it still won’t have
- Polished art, animation and UX refinement (Dino animations, celebrations)
- App Store reputation, reviews, and 100k+ existing user base
- Ten years of accumulated product polish and iterative improvements
- Existing school licensing, volume deployment relationships and support workflows
- Documented COPPA compliance and any legal/privacy QA the vendor already completed
What remains hard
- Brand trust
100k+ downloads
- Brand trust
4.6 ★ App Store rating
- Brand trust
10 years of updates
- Compliance and regulation

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build an iOS/iPadOS SwiftUI app (Swift 5, Xcode) implementing a kids clock-learning app: include SwiftUI lesson UI, three question types (multiple-choice, drag-to-set-hand, listening), free-play clock with AVSpeechSynthesizer narration, on-device Core Data progress (stars, streaks, unit completion), StoreKit subscription to unlock premium units, and CSV export/report for teachers; explicitly out of scope: polished character art/animations, App Store submission & reviews, and enterprise school licensing sales; include error handling, localization-ready strings, and unit/UI tests.
How we checked
How the score was reached
- Partly verdict base52
- 3/3 assessment runs agreed+4
- Hard moats found in the evidence-3
- Evidence score53
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.
