Chainkeep is a habit tracker built on two ideas: checking off a habit should take one tap, and your streak should be right. Most habit apps break a "three times a week" habit on the first day you rest. Chainkeep counts it the way you planned it: a week kept is a week kept. Daily habits, specific days, every few days, times per week or per month, and habits you are quitting are all tracked honestly. ONE TAP A DAY • Everything due today on one screen, ticked off in a single tap • Skip a day without breaking anything, or pause a habit for a holiday • Split your day into parts, like morning and evening • Quit habits count your days clean • Hold the app icon to add a habit straight away STREAKS THAT FIT YOUR SCHEDULE • Weekly and monthly targets keep their own streaks • A grace day for the odd miss, if you want one • Habit strength shows how established a habit is, even after a slip • Set a finish line, like 30 or 66 days, and watch it come closer EVERY STAT, FREE • Six months of calendar for every habit • Completion over the last 30 days and the last six months • The days of the week you actually do it, and the time you usually do • Longest runs, totals, and a month in review you can share REMINDERS THAT LEARN • A reminder at the time you choose • Smart nudges learn when you usually do a habit and remind you then YOUR LOOK • 24 colour themes to choose from • Light and dark themes, with a pure black option PRIVATE BY DESIGN • No account, no ads, no tracking • Your habits stay on your own devices • Export and import your data whenever you like CHAINKEEP PRO One payment, yours for good. No subscription. • Unlimited habits (free keeps six) • As many reminders as each habit needs • Archive habits you have finished • Sync between your iPhone and iPad through your own private iCloud Your stats stay free, always.

Verdict
The clearest difference is rating: Chainkeep at 3.0 against OnSolve's 1.9. Chainkeep also leads on update cadence (weekly vs monthly). OnSolve's advantage is in-app purchases (none vs 1) and ratings volume (32 vs 2). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Chainkeep sells 1 one-off in-app purchase. OnSolve asks for nothing beyond the download.
Chainkeep holds the better App Store score, 3.0 against 1.9. That said, the two scores are not equally well evidenced: OnSolve has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 14% of OnSolve's written reviews are positive against 0% of Chainkeep's, so the app with the better star average is not the one people write more warmly about.
OnSolve ships an update monthly, Chainkeep weekly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
