# Atomic Mail vs Tupo

The clearest difference is rating: Tupo at 5.0 against Atomic Mail's 4.5. Tupo also leads on monetization model (free vs freemium) and update cadence (every 5 days vs every 2 weeks). Atomic Mail's advantage is ratings volume (288 vs 3). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Atomic Mail sells 3 in-app purchases, starting at $5.99 per month and Tupo sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
