# 2PEAK vs Strength IO

The clearest difference is rating: Strength IO at 5.0 against 2PEAK's 3.9. Strength IO also leads on update cadence (every 6 days vs every 2 weeks). 2PEAK's advantage is ratings volume (11 vs 1) and iOS requirement (15.1 vs 26.4).

Both are free to download. 2PEAK sells 10 in-app purchases, starting at $14.99 per month and Strength IO sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Strength IO holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: 2PEAK has 11 ratings behind it against 1, so its average is the more settled of the two.
