# Ballbank vs Clinometer+

The clearest difference is in-app purchases: Ballbank at none against Clinometer+'s 1. Ballbank also leads on review sentiment (67% vs 48%) and iOS requirement (12.0 vs 17.6). Clinometer+'s advantage is update cadence (every 2 months vs every 8 months) and ratings volume (1K vs 44). On price, rating, ads and device support there is nothing between them.

Both are free to download. Clinometer+ sells 1 one-off in-app purchase. Ballbank asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for Ballbank against 4.5 for Clinometer+. That said, the two scores are not equally well evidenced: Clinometer+ has 1K ratings behind it against 44, so its average is the more settled of the two. Written reviews are what separate them: 67% of Ballbank's written reviews are positive against 48% of Clinometer+'s.

Ballbank ships an update every 8 months, Clinometer+ every 2 months. Both last shipped on October 24, 2026.
