# GymBook ・ Strength Training vs IronStack

The clearest difference is ratings volume: GymBook ・ Strength Training at 2.4K against IronStack's 7. IronStack's advantage is update cadence (every 3 days vs weekly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. GymBook ・ Strength Training sells 13 in-app purchases, starting at $1.99 per month and IronStack sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for GymBook ・ Strength Training against 4.9 for IronStack. That said, the two scores are not equally well evidenced: GymBook ・ Strength Training has 2.4K ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 95% of GymBook ・ Strength Training's written reviews are positive against 100% of IronStack's.

GymBook ・ Strength Training ships an update weekly, IronStack every 3 days. The most recent releases landed on September 25, 2026 and September 11, 2026 respectively.
