Apple Watch Wooden Fish FAQ

Echo is the first Apple Watch app that turns your wrist into a cyber wooden fish. Using the built-in accelerometer at a high sampling rate, it detects wrist-tapping gestures with high precision and delivers real haptic feedback through the Taptic Engine — no screen tapping required. It also features an exercise mode for earning merit with every step via HealthKit integration, and auto-logs mindful minutes to Apple Health. It is designed to act as a tactile anchor, helping you find calm through simple wrist gestures.

Echo reads the Apple Watch accelerometer at a high sampling rate to detect wrist-tapping gestures. Its custom anti-false-trigger algorithm distinguishes intentional tapping gestures from normal arm movements, walking, or running with high accuracy. Each detected gesture triggers a realistic haptic response through the Taptic Engine and an optional sound effect. This physical, tactile experience is designed to keep you highly engaged in mindfulness compared to standard visual apps.

Yes. Echo runs natively on Apple Watch as an independent watchOS application. Using WKExtendedRuntimeSession, it continues operating even when the screen is off — a critical feature that allows you to meditate or count merit in places like open offices, public transit, or shared environments. All features — motion detection, haptic feedback, and merit counting — function independently without your iPhone.

Echo runs on Apple Watch Series 6 and later (including Apple Watch SE 2nd generation) with watchOS 10.0 or newer. It is a native, independent watchOS app and works on the wrist without your iPhone nearby. It is not available on iPhone or iPad.

Yes. Silent Mode uses only the Taptic Engine for vibration with zero audio output, so you can knock and earn merit discreetly in open offices, meetings, or while commuting. Combined with screen-off operation via WKExtendedRuntimeSession, Echo keeps working quietly even when the display is off.

Exercise mode connects to Apple HealthKit to read your daily step count. Every step is converted into merit points — transforming your walk into an active meditation practice. The app displays exercise duration, step count, and merit earned in real-time. This design makes it incredibly easy to integrate mindfulness into your existing daily walks, commute, or exercise routines rather than demanding a dedicated block of free time.

The activity heatmap is a calendar grid in Settings that lights up each day you practice with Echo — a contribution graph for mindfulness, built entirely on your Watch. A consecutive-day streak counter rewards showing up daily, so you can watch your consistency grow week by week. All activity history is stored locally and never uploaded anywhere.

Echo is a paid app on the App Store with no subscriptions and no in-app purchases. A single purchase unlocks all features permanently: 5 premium wooden fish styles, 6 high-fidelity sound effects, exercise merit mode, and HealthKit mindfulness integration. You buy it once, own it forever, and can focus on your mindfulness practice without any hidden costs or ads.

No. All motion and health data is processed locally on your Apple Watch in real-time. There are no user accounts, no cloud storage, and no data uploads of any kind. HealthKit data (step count and mindful minutes) stays encrypted on your device and is never shared with third parties. This privacy-by-design architecture complies fully with security and privacy best practices.
