# BMI Formula vs VO2 STUDIO

The clearest difference is ads: VO2 STUDIO at none against BMI Formula's shown. VO2 STUDIO also leads on update cadence (every 3 months vs every 60 months) and iOS requirement (15.0 vs 18.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BMI Formula ships an update every 60 months, VO2 STUDIO every 3 months. The most recent releases landed on October 6, 2026 and October 7, 2026 respectively.
