# Hey Trainer vs Build

The clearest difference is update cadence: Hey Trainer at every 2 days against Build's every 9 days. Build's advantage is ratings volume (25 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Hey Trainer sells 2 in-app purchases, starting at $9.99 per month and Build 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 — 5.0 for Hey Trainer against 5.0 for Build. That said, the two scores are not equally well evidenced: Build has 25 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Hey Trainer ships an update every 2 days, Build every 9 days. Both last shipped on October 24, 2026.
