# Sort It 3D vs SUDU

The clearest difference is rating: SUDU at 5.0 against Sort It 3D's 4.6. SUDU also leads on update cadence (every 4 days vs fortnightly). Sort It 3D's advantage is ratings volume (394K vs 3) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
