# Satellite Transponders HD vs IoT USB

The clearest difference is in-app purchases: IoT USB at none against Satellite Transponders HD's 1. IoT USB also leads on device support (3 vs 1) and iOS requirement (9.0 vs 11.0). On price and ads there is nothing between them.

Both are free to download. Satellite Transponders HD sells 1 one-off in-app purchase. IoT USB asks for nothing beyond the download.
