Turn today’s moments into a message for your future. TimeMessage lets you create a private time capsule containing everything that makes a memory feel real: • photos from the camera or your library • videos recorded now or selected from Photos • voice messages recorded inside the app • text notes and web links • documents and other files Choose an opening date, then seal the capsule. Until that day, TimeMessage keeps its contents locked. The first opening requires an internet connection: the app compares multiple trusted HTTPS time sources and never relies on the iPhone clock to grant early access. After a successful opening, the contents remain available offline. YOUR MEMORIES STAY YOURS Capsules are stored locally on the device. There is no TimeMessage account, proprietary server or app-level synchronization. Normal encrypted iPhone and iCloud backups are not disabled. SHARE A COMPLETE CAPSULE Export a self-contained .tmcapsule file through the iOS share sheet. A recipient with TimeMessage can import it into their local archive and must respect the same opening date. SIMPLE, PERMANENT UPGRADE The free version stores one capsule at a time, whether created or received. A single non-consumable purchase unlocks unlimited capsules forever. No subscription. Purchases can be restored through the App Store. Version 2.0 is a complete native SwiftUI rewrite. Existing TimeMessage 1.x archives are migrated automatically and previous users retain full access.

Verdict
The clearest difference is ads: Time Messages at none against GPS時速表's shown. GPS時速表's advantage is update cadence (every 6 days vs every 4 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
