Verdict
The clearest difference is ratings volume: ST Coach at 52 against Master Training's 1. ST Coach also leads on iOS requirement (11.0 vs 16.4). Master Training's advantage is review sentiment (88% vs 73%) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for ST Coach against 5.0 for Master Training. That said, the two scores are not equally well evidenced: ST Coach has 52 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 73% of ST Coach's written reviews are positive against 88% of Master Training's.
ST Coach ships an update every 2 months, Master Training every 3 weeks. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
