Verdict

The call

The clearest difference is monetization model: Coachify AI at free with in-app purchases against FST's subscription. Coachify AI also leads on rating (4.6 vs 4.1) and update cadence (every 3 days vs every 3 months). On price, ads, in-app purchases and device support 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. FST sells 2 in-app purchases, starting at $24.99 per month and Coachify AI sells 11 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Coachify AI holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Coachify AI has 2K ratings behind it against 138, so its average is the more settled of the two. Written reviews point the same way: 40% of FST's written reviews are positive against 59% of Coachify AI's.

UpkeepUpdate frequency

FST ships an update every 3 months, Coachify AI every 3 days. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
