# IoTronics vs All in One Formula

The clearest difference is in-app purchases: IoTronics at none against All in One Formula's 1. IoTronics also leads on iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

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