# RP Hypertrophy vs Built With Science+

The clearest difference is rating: Built With Science+ at 4.8 against RP Hypertrophy's 4.4. Built With Science+ also leads on ratings volume (5.1K vs 291) and device support (3 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. RP Hypertrophy sells 5 in-app purchases, starting at $34.99 per month and Built With Science+ sells 4 in-app purchases, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

Built With Science+ holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Built With Science+ has 5.1K ratings behind it against 291, so its average is the more settled of the two.
