# Flexibility Trainer vs Flexible Strength Academy

Flexibility Trainer and Flexible Strength Academy are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Flexibility Trainer sells 11 one-off in-app purchases and Flexible Strength Academy sells 1 in-app purchase, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 14, 2026 and September 12, 2026 respectively.
