# Arduino BT Controller vs BLE Controller

The clearest difference is review sentiment: BLE Controller at 100% against Arduino BT Controller's 50%. BLE Controller also leads on rating (4.7 vs 2.0) and in-app purchases (none vs 1). Arduino BT Controller's advantage is update cadence (every 8 days vs every 2 weeks). On price there is nothing between them.

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