# Ballistic vs Buoyancy Calc

The clearest difference is rating: Buoyancy Calc at 3.1 against Ballistic's 1.2. Buoyancy Calc also leads on in-app purchases (none vs 1). Ballistic's advantage is review sentiment (49% vs 40%) and ratings volume (91 vs 25). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Ballistic sells 1 one-off in-app purchase. Buoyancy Calc asks for nothing beyond the download.

Buoyancy Calc holds the better App Store score, 3.1 against 1.2. Both are backed by a comparable volume of ratings — 91 and 25 respectively. Written reviews complicate that: 49% of Ballistic's written reviews are positive against 40% of Buoyancy Calc's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
