Time doesn't pass. It collects. Plop is a calm focus timer that turns the time you focus into water dripping into a jar. Choose a duration, then watch the water rise as you work. YOUR EFFORT SURVIVES THE BREAK Locking your phone doesn't have to break the flow. Leave Plop for another app and the jar cracks, but your effort is not erased: most of the water stays. Come back and finish the remaining time, and the spilled water returns while the crack becomes a golden mend. Mending is always available; the way back never closes. EVERY FOCUS LEAVES A MARK Every focus you finish or leave for now stays visible as its own jar. See the rhythm of your current week, browse your collection month by month, and watch all your accumulated effort live in a lifetime jar. Plop keeps continuity visible without turning it into a target. YOUR RHYTHM, YOUR WAY Pick 15, 25, or 45 minutes, or set any duration from 5 to 180 minutes. Start your week on Monday or Sunday, then adjust sound, haptics, calm mode, keep-awake, and daily reminders. Use Plop in English or Turkish. Plop also offers a full-screen experience designed for iPad. YOURS ALONE Plop works offline. There is no account, advertising, analytics, or data transfer; your focus records stay on your device. Choose a duration. Let the first drop fall.
