# Open vs StrumTune

The clearest difference is in-app purchases: StrumTune at none against Open's 1. Open's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.

Both are free to download. Open sells 1 one-off in-app purchase. StrumTune asks for nothing beyond the download.
