# Built With Science+ vs Recomp AI

The clearest difference is ratings volume: Built With Science+ at 5.3K against Recomp AI's 2. Built With Science+ also leads on update cadence (fortnightly vs every 5 weeks) and device support (3 vs 1). Recomp AI's advantage is review sentiment (100% vs 80%).

Both are free to download. Built With Science+ sells 4 in-app purchases, starting at $29.99 per month and Recomp AI sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
