# Atmozen vs SEMS+

The clearest difference is rating: Atmozen at 5.0 against SEMS+'s 2.4. Atmozen also leads on iOS requirement (13.0 vs 15.1). SEMS+'s advantage is update cadence (every 8 days vs every 2 months) and ratings volume (12 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
