# ServoControl vs TCP

The clearest difference is in-app purchases: ServoControl at none against TCP's 1. ServoControl also leads on iOS requirement (12.0 vs 26.0). On price, ads and device support there is nothing between them.

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