Since & Until: Time Tracker helps you keep meaningful dates in view. Track how long it has been since you quit smoking, started a gym streak, had your last migraine, serviced your car, welcomed a baby or celebrated an anniversary. Count down to a holiday, exam, appointment or any date you want to prepare for.

Create an event, choose whether it counts since a past moment or until a future one, then let the app keep the timer current. Use the list view for detailed cards or the grid view when you want to scan several events at once. Add a home-screen widget to keep one important timer visible without opening the app.

Cards can be reordered with drag and drop in both list and grid views, so your most important timers stay where you expect them. The order is saved automatically.

Time formats are flexible. Choose the units you want to see, from years and months down to seconds. Set one global format for the app or override it on a single event when a countdown or streak needs different detail.

Reset history helps you understand progress over time. Each reset records the date, how long the streak ran before it, and the gap since the previous reset, so a setback does not erase the record.

Per-event alarms let you add reminders with a date and time, repeat them once, daily, weekly, monthly or yearly, and use any ringtone available on your device.

The event editor is designed to be quick to use. Name, date, category, alarm and appearance settings are one tap away, with Save always visible.

Personalise cards with solid colours, your own image or one of the photographic backgrounds: Drift, Aurora, Starfield, Star Trails, Summit, Canyon, Mist, Skyline, Open Water and Dewfall.

The app is free with ads. An in-app purchase removes ads. Backup and restore use a local file that you export and keep yourself.
