About

Days Since

Features
Read full description

Days Since answers one question: how long has it been since you last did this? Changed the furnace filter. Watered the plants. Called your parents. Replaced your toothbrush. Had the oil changed. These are the things that matter but never fit on a calendar, because they don't happen on a schedule โ€” they happen when they happen. Add a tracker. Tap once when you do the thing. That's the whole app. ONE TAP, FROM ANYWHERE Log a completion from the list, the detail screen, a Home Screen widget, your Apple Watch, or by asking Siri. It takes a second, so you'll actually do it.

Verdict

The call
