Wish it had the features like the Android version

Works pretty well, but the Android version has a lot more functionality. Make the iOS version like that!

Mixed bag

Definitely a helpful tool for working with BLE Devices but I’ve been having issues lately where it’s not reading characteristic values for some reason. Please update!

The worst app i’ve ever used

This app crashed three times while i was trying to write a one-star review saying it crashes constantly. Seems to be a serious multithreading issue. I’m amazed this made it through QA.
