# Mechanical Formula vs Nautlius

The clearest difference is in-app purchases: Nautlius at none against Mechanical Formula's 1. Nautlius also leads on rating (5.0 vs 4.7). Mechanical Formula's advantage is ratings volume (34 vs 2) and iOS requirement (13.0 vs 18.0). On price, ads and device support there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase. Nautlius asks for nothing beyond the download.
