# Flexer vs Built Workout

The clearest difference is ratings volume: Built Workout at 357 against Flexer's 28. Flexer's advantage is review sentiment (95% vs 84%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Flexer sells 11 in-app purchases, starting at $4.99 per 7 days and Built Workout sells 2 in-app purchases, starting at $7.99 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 — 4.7 for Flexer against 4.8 for Built Workout. That said, the two scores are not equally well evidenced: Built Workout has 357 ratings behind it against 28, so its average is the more settled of the two.
