Lose track of time in the shower? Rosa Knock sends gentle haptic "knocks" to your wrist at intervals you choose. No sound, no stress — just a friendly tap to keep you on track.
When you're focused on something — showering, meditating, or just lost in thought — time slips away. Rosa Knock keeps you grounded without being intrusive.
What feels like 5 minutes is actually 20. Rosa Knock gently reminds you so you stay on schedule.
Meditate or stretch without watching a clock. A subtle knock tells you when time's up.
Work in short bursts with periodic check-ins. Stay in flow without losing track.
Create and customize your activities on your iPhone, then run them directly on your Apple Watch — no phone needed during your session.
Choose the timing style that works best for your activity.
Pick an activity and start — Rosa takes care of the rest. The watch app is designed to be glanceable and distraction-free.
Works even when your screen is off. Haptics continue in the background.
Rosa Knock runs entirely on your devices. No accounts. No backend. No data leaves your device.
We don't track how you use the app. We don't store anything. It's just you and your watch.
