About
When did you last change the bedsheets? Descale the coffee machine? Water the plants, replace the toothbrush, give the dog its flea treatment?
Rewen remembers for you. Add the things you keep forgetting, and it shows how long it has been since you last did each one — "6 days ago", "3 months ago". When you do it again, tap Done. That's the whole app.
CALM BY DESIGN
No "overdue", no streaks, no scores, no guilt. Rewen states how long it has been, and once it knows you, how often you usually do something. Doing things early or late is normal; the app never judges.
IT LEARNS YOUR RHYTHM
After a few records, Rewen works out your natural rhythm — "usually every ~9 days" — without any setup. Or set a rhythm yourself: every 7, 14, 30, 60 days, or your own number.
REMINDERS THAT DON'T NAG
Turn on a reminder for any item and get one calm notification when its rhythm has passed — once, not every day. Mark it Done or choose Remind tomorrow right from the notification.
EVERYTHING STAYS ON YOUR PHONE
No account, no cloud, no analytics, no third-party code. Rewen never connects to the internet. Your data is yours: it's in your normal iPhone backup, and you can export it as a file any time.
FREE, WITHOUT LIMITS
Track as many things as you like.
ON YOUR HOME SCREEN
Add the Rewen widget and see what needs you without opening the app. Tap Done right there.
Also: backdate things you forgot to record, fix mistakes with Undo, keep a simple history per item, full support for large text, VoiceOver and Dark Mode.
Rewen is for anyone who keeps asking "when did I last…?" — and would rather have a quiet answer than another to-do list.
