# Stronger vs Flexius

The clearest difference is update cadence: Stronger at every 3 days against Flexius's every 3 weeks. Stronger also leads on ratings volume (17K vs 2) and chart position (#194 vs unranked). Flexius's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stronger sells 15 in-app purchases, starting at $9.99 per month and Flexius sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Flexius holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Stronger has 17K ratings behind it against 2, so its average is the more settled of the two.

Stronger ships an update every 3 days, Flexius every 3 weeks. The most recent releases landed on October 18, 2026 and October 2, 2026 respectively.
