# Tuta Mail vs OSO+

The clearest difference is price: Tuta Mail at Free against OSO+'s $19.99. Tuta Mail also leads on update cadence (weekly vs every 2 months) and ratings volume (3.8K vs 6). OSO+'s advantage is review sentiment (100% vs 65%) and rating (5.0 vs 4.7). On ads, in-app purchases, monetization model and device support there is nothing between them.
