# Built With Science+ vs GYMTIME

The clearest difference is monetization model: Built With Science+ at free with in-app purchases against GYMTIME's subscription. Built With Science+ also leads on ratings volume (5.4K vs 9) and device support (3 vs 1). GYMTIME's advantage is review sentiment (100% vs 80%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Built With Science+ sells 4 in-app purchases, starting at $29.99 per month and GYMTIME sells 6 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

GYMTIME holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Built With Science+ has 5.4K ratings behind it against 9, so its average is the more settled of the two.
