# ZenConfig vs BLE Controller

The clearest difference is update cadence: BLE Controller at every 2 weeks against ZenConfig's every 11 months. BLE Controller also leads on ratings volume (26 vs 2) and iOS requirement (12.0 vs 16.4). ZenConfig's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ZenConfig holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: BLE Controller has 26 ratings behind it against 2, so its average is the more settled of the two.

ZenConfig ships an update every 11 months, BLE Controller every 2 weeks. Both last shipped on October 24, 2026.
