Stop managing to-dos. Just remember when you last did it. "When did I last wash the sheets?" "When did I change the water filter?" "When did I last call my parents?" Some things you can never remember. When'd I records just the date you did them. No goals, no nagging notifications, no checklists. Tap once and it's logged as today. ■ See how long it's been Every item shows the days since you last did it. The longer it's been, the more it stands out. ■ A timeline where distance means time The space between dots is the actual gap between dates. Busy stretches look dense. The months you skipped show up as empty space. ■ Photos and notes Attach up to 10 photos and a short note to any record. ■ Widgets and Lock Screen Check what's overdue from your Home Screen, and log without opening the app. You can even record straight from the Lock Screen. (iOS 16.4+) ■ An optional evening nudge Once a day, if you want it. Off by default. ■ Entirely on your device No account, no server, no ads. Your records stay on your phone. Export and import backup files yourself, and an automatic iCloud copy brings everything back if you switch phones or reinstall. ■ Buy once One purchase unlocks everything. No in-app purchases, no subscriptions, no ads.

Etch is a quiet habit tracker. One tap marks the day. Over time, the marks become your rhythm. CHECK IN WITH ONE TAP Every habit is a circle. Tap it and it turns white. Missed a day? Step back and fill it in. SEE YOUR RHYTHM The Log shows the last 7 days or the last 26 weeks as a grid of dots, so streaks and gaps are easy to spot. Open any habit for its streak, best run, total, and a month-by-month calendar. SET YOUR OWN PACE Pick the weekdays each habit is due. Days off show as gray dots and never break a streak, and checking in on a rest day still counts. FITS YOUR DAY Up late? Set your day to end as late as 5 a.m., so a check-in after midnight still counts for the day before. WIDGETS Check in straight from your Home Screen, and see recent days at a glance, in three sizes. PRIVATE BY DESIGN • No account, no ads, no tracking • Your habits sync through your own private iCloud • The developer never sees your data Free and open source: github.com/nvlznn/etch

Verdict
The clearest difference is price: Etch at Free against When'd I's $3.99. When'd I's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On ads and in-app purchases there is nothing between them.
