# BLE Controller vs ESP

The clearest difference is in-app purchases: BLE Controller at none against ESP's 1. BLE Controller also leads on device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price and ads there is nothing between them.

Both are free to download. ESP sells 1 one-off in-app purchase. BLE Controller asks for nothing beyond the download.
