# Caliber vs StronkBar

The clearest difference is ratings volume: Caliber at 6.2K against StronkBar's 2. Caliber also leads on chart position (#148 vs unranked) and iOS requirement (15.1 vs 18.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Caliber sells 8 in-app purchases, starting at $3.00 per month and StronkBar sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

StronkBar holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Caliber has 6.2K ratings behind it against 2, so its average is the more settled of the two.

Caliber ships an update fortnightly, StronkBar every 3 weeks. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
