VibeCraft Timer vs LockIN

Haptic Countdown Timer for Apple Watch Silent. Discreet. Customizable. VibeCraft Timer is a standalone Apple Watch app that replaces loud alarms with gentle haptic vibrations. Set a countdown timer, choose your vibration intensity, and feel a quiet nudge on your wrist when time is up — no sound, no screen glare, no interruptions. KEY FEATURES • Custom Haptic Intensity: Choose how strong and how often your Apple Watch vibrates at the end of the countdown. Higher intensity means more repeated vibrations for a more noticeable alert. • Standalone watchOS App: Runs entirely on Apple Watch — no iPhone required during use. • 3-Second Test Mode: Preview your selected vibration pattern instantly before setting your timer. • Slide-to-Control UI: Use intuitive swipe gestures to cancel a running timer. • Adjust on the Fly: Change vibration intensity even while the countdown is active. • No Data Collected: 100% private — zero data tracked or stored. HOW IT WORKS 1. Open VibeCraft Timer on your Apple Watch. 2. Tap “Set Vibration” on the home screen. 3. Choose your desired vibration intensity. 4. Start the countdown timer. 5. When time's up, your watch vibrates silently — repeated pulses based on your chosen intensity level. PERFECT FOR Meditation, breathwork, yoga, classroom exams, quiet meetings, focus sprints (Pomodoro), HIIT intervals, or any situation where a silent wrist alert is better than a beeping alarm. PRICING VibeCraft Timer is free to download and includes all core features. A one-time Premium upgrade unlocks Smooth Mode — vibration that slowly builds up to your set level instead of starting abruptly. Perfect for meditation, naps, or soft reminders where a gentle onset makes all the difference. Developed by YU CHEN YEH - Franky | Independent Developer

Premium unlocks two studio coach voices and the monthly health report. Everything needed to train — heart-rate coaching, plans, the field test, progress — is free. Heart rate requires an Apple Watch. On the Simulator or an iPhone without a paired watch, the run screen will wait for a heart-rate source. There is no account system, no sign-in, and no server. Nothing in the app is gated behind an identity, so no demo credentials are needed. HEALTHKIT HealthKit data is never uploaded to a server — LockIN has no backend and no network path for it. Heart rate, workouts, and routes are read from and written to HealthKit on the device; training data is stored locally in SwiftData. No HealthKit data is shared with third parties, sold, or used for advertising. The app's one third-party SDK is Sentry, for crash reporting, and it never receives HealthKit data: sendDefaultPii, attachScreenshot and attachViewHierarchy are disabled and tracing is zero, because a crash screenshot of the run screen would itself be heart-rate data. PERMISSIONS The Health and Apple Music screens explain why access is wanted and then always present the system permission sheet. Declining is available on Apple's own sheet; onboarding completes either way.
