Verdict
The clearest difference is in-app purchases: nRF Connect for Mobile at none against Lecture AI's 2. nRF Connect for Mobile also leads on iOS requirement (17.0 vs 26.5). Lecture AI's advantage is update cadence (daily vs every 5 weeks). On price, ads and device support there is nothing between them.

Bugs and requests
nRF Connect for Mobile
Reported bugs
4 issues- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.
