# Caffeine App vs Tazza

The clearest difference is rating: Tazza at 5.0 against Caffeine App's 4.6. Caffeine App's advantage is ratings volume (341 vs 2) and iOS requirement (18.0 vs 26.2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Caffeine App sells 1 one-off in-app purchase and Tazza sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
