# Caliber vs FitOne Training

The clearest difference is in-app purchases: FitOne Training at none against Caliber's 10. FitOne Training also leads on iOS requirement (13.5 vs 15.1). Caliber's advantage is update cadence (fortnightly vs every 17 months) and chart position (#164 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. Caliber sells 8 in-app purchases, starting at $3.00 per month. FitOne Training asks for nothing beyond the download.

Caliber ships an update fortnightly, FitOne Training every 17 months. The most recent releases landed on November 6, 2026 and October 27, 2026 respectively.
