"When did I last do that?" Bike oil changes, haircuts, salon visits, AC cleaning, doctor appointments, pet care — things you do again and again, but once enough time passes, you can't remember when you last did them. When Again? clears up that little everyday question with a single tap. Just log the date. The app automatically counts the days since you last did it, learns your average interval from your own records, and gives you a heads-up when it's about time. ■ Who it's for ・People who forget when their bike or car was last serviced ・Anyone managing regular salon, hair, or nail appointments ・People tracking doctor visits, medication, or health habits ・Anyone who wants to stop thinking "wow, it's already been a while" ・People who want to start right away — no account needed ■ Key features ◎ See the days at a glance Your items line up on the home screen, each with a badge showing how many days since you last did it. What needs doing now is obvious. ◎ "About time" reminders, automatically The app learns your average interval from your records, gathers the items coming due at the top of the home screen, and reminds you with notifications too. ◎ Track anything Use the preset categories or add your own with custom icons and colors. From bike maintenance to beauty to health — manage it all in one app. ◎ Photos, tags, amounts, and notes It's more than a date log. Add up to 5 photos, tags, the amount you spent, and notes to each record — so you can look back on what state it was in last time and how much it cost. ◎ Detailed history and stats The detail screen shows stats like "since last time," "average interval," and totals, plus a month-by-month timeline. ◎ Search Search across notes, tags, and item names to find past records instantly. ◎ Easy backup Save and restore all your records to a file (photos included). CSV export is also supported. ◎ Dark mode Choose system, light, or dark. ■ Privacy first All your records are stored only on your device. No account, no login. We never send your records to a server — so you can start with peace of mind. ■ Pricing The core features are free. Some premium features are available via a one-time in-app purchase. Leave your everyday "when was that again?" to When Again?
