# OnSolve vs Chainkeep

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.

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.
