Verdict

The call

The clearest difference is rating: nRF Connect for Mobile at 4.5 against Fish Helper Pro's 1.0. nRF Connect for Mobile also leads on update cadence (every 5 weeks vs every 37 months) and ratings volume (479 vs 1). Fish Helper Pro's advantage is review sentiment (100% vs 71%) and iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

nRF Connect for Mobile holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: nRF Connect for Mobile has 479 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 71% of nRF Connect for Mobile's written reviews are positive against 100% of Fish Helper Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

nRF Connect for Mobile ships an update every 5 weeks, Fish Helper Pro every 37 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.

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.
