Since · Until · Last time

Track your marks in time

The day you met, the day you quit smoking, the day the trip begins. ATO counts the days since and the days until, and lets you know when a milestone arrives.

Day 1
Since that day, until the next
Count up, count down, or both at once. One event shows how far you've come and how far there is to go.
100 days
Milestones, set out for you
100 days, 1 year, 1,000 days, 10 years. Create an event and the milestones line up on their own, with a notification on the big ones. Add photos and notes to remember each one.
1 year
When did I last…?
Washed the sheets, called home. Tap “Did it again” each time and the count starts over, with your average gap and longest stretch alongside.
1,000 days
Count it your way
Show days, weeks and days, years-months-days, or hours. Count from an exact time (Pro). Sort events by category and color.
5 years
A milestone on one card
Make a magazine-style share card, save it to Photos or send it straight to friends. Several designs to choose from.
10 years
Everything at a glance
