Verdict
The clearest difference is ratings volume: Gym Rank at 171 against StrengthIn's 1. Gym Rank also leads on update cadence (every 9 days vs every 3 weeks) and iOS requirement (15.0 vs 17.6). StrengthIn'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. StrengthIn sells 3 one-off in-app purchases and Gym Rank sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
StrengthIn holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Gym Rank has 171 ratings behind it against 1, so its average is the more settled of the two.
StrengthIn ships an update every 3 weeks, Gym Rank every 9 days. The most recent releases landed on September 23, 2026 and October 16, 2026 respectively.
