Verdict
The clearest difference is monetization model: GymBook ・ Strength Training at free with in-app purchases against Thrive by Katie's subscription. GymBook ・ Strength Training also leads on ratings volume (2.4K vs 427). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. GymBook ・ Strength Training sells 13 in-app purchases, starting at $1.99 per month and Thrive by Katie sells 6 in-app purchases, starting at $12.99 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 Thrive by Katie. That said, the two scores are not equally well evidenced: GymBook ・ Strength Training has 2.4K ratings behind it against 427, 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 Thrive by Katie's.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
