When? — Last Done Tracker

When did you last change the water filter? Water the plants? Rotate the car tyres? When? answers that. Most apps nag you every single day. When? does the opposite: it remembers the last time you did something and stays quiet until it is actually due again. HOW IT WORKS • Add the things you repeat — bedsheets, air filter, plant watering, car service, anything. • Tap "Done Now" when you do it. That is the whole interaction. • Give it an interval, and When? reminds you the moment it comes due. WHAT YOU GET • A clear list, sorted by what is most overdue • Ready-made templates for home, health, garage, tech, pets and garden • Reminders that arrive exactly when an item is due • Categories, search and simple statistics • Backup and restore your list as a file • English and Turkish • Works completely offline — your list stays on your device FREE AND PRO The free plan tracks 3 items, for as long as you like — no time limit, no account, no ads. When? Pro removes the limit with a single one-time payment. It is not a subscription: nothing renews and you are never charged again.
