Time blindness is real: you start something and, before you know it, far more time has passed than you thought. A shower, getting ready, a study block, focused work — the minutes quietly slip away. RosaKnock is the gentle tap that keeps you aware of time. Rosa "knocks" on your Apple Watch or iPhone at the interval you choose, so the time comes to you: no glancing, no alarms, no breaking your flow. Run a session wherever you are. Start it on your Apple Watch for a tap on the wrist, or run it right on your iPhone — no Watch needed. iPhone sessions keep going in the background, so the timer carries on while your phone is locked or in your pocket. The activities are yours to shape. Set one up with a name, an icon, a color, a length, and how often you'd like a knock — whether it's a morning routine, a bath, a study session, or anything you like. Keep the knock silent as a haptic, or add a sound. It's your rhythm. No loud alarms. Just a gentle nudge that keeps time from disappearing — so you stay present and finish on time. FEATURES • Gentle knocks on Apple Watch or iPhone at your chosen interval • Run sessions on your iPhone alone — no Apple Watch required • Sessions keep running in the background • Create your own activities — name, icon, color, duration, and knock interval • Silent by default, with an optional knock sound per activity • Session history and insights • Apple Watch complications and Control Center support • Beautiful, calm, water-inspired interface • Available in your language Perfect for: • ADHD and time blindness • Focused work and study blocks • Morning routines and getting ready on time • Shorter, more mindful showers • Calm, distraction-free days Stay aware. Finish on time.
