# 30 day vs GymJam

The clearest difference is ads: GymJam at none against 30 day's shown. GymJam also leads on rating (5.0 vs 4.7). 30 day's advantage is ratings volume (154 vs 1) and iOS requirement (13.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 30 day sells 1 one-off in-app purchase and GymJam sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

GymJam holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 30 day has 154 ratings behind it against 1, so its average is the more settled of the two.

30 day ships an update every 9 days, GymJam every 11 days. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
