Track the days that matter. Since, until, or both. ATO quietly tracks the days that matter to you — whether counting forward from a meaningful moment or counting down to something you're looking forward to. — WHEN DID I LAST…? — "3 days since my last coffee." "12 days since I changed the sheets." Log it with one tap each time and the count starts over — with your average gap and longest streak. — THREE WAYS TO TRACK — • Since: How many days since you started a new job, quit smoking, or met someone special • Until: Count down to a wedding, graduation, or vacation • Both: Track in both directions at once — see how far you've come and how far you have to go — MILESTONES, AUTOMATICALLY — ATO generates milestones for you: 100 days, 1 year, 1000 days, 10 years, and more. Each milestone is a quiet celebration of time passing. You can also add your own custom milestones. — MEMORIES ALONG THE WAY — Attach photos and notes to milestones. Look back and remember what that day felt like. — GLANCEABLE WIDGET — iOS home screen widget shows your next milestone at a glance — with a progress ring so you can see how close you are. — SHARE YOUR MOMENTS — Generate beautiful share cards with your milestone progress. Magazine-style design, ready for social media. — STATISTICS — See your longest-tracked event, upcoming milestones across all events, and monthly milestone celebrations. — DESIGNED TO BE CALM — No clutter, no gamification. ATO uses a soft, editorial design with muted tones and gentle shapes. It's a quiet companion, not a noisy app. — YOUR DATA STAYS YOURS — • 100% local-first: all data stored on your device • No account required, no sign-up • No analytics or tracking • Optional iCloud backup (one-time purchase) to safeguard your data — NOTIFICATIONS, NOT NOISE — Only major milestones trigger notifications (100 days, 1 year, 1000 days...). No daily spam. — ATO PRO (ONE-TIME PURCHASE) — • Unlimited events • Every widget, including Lock Screen and Photo widgets • Your count on the Lock Screen and Dynamic Island • Exact times, plus years/months/days, weeks or hours • App icons and share card designs • Lock the app with Face ID • Import birthdays from Contacts • iCloud backup ATO — because every day counts.
