Review on 🚗 Cutting-Edge Wireless Bluetooth Car Battery Tester for Android & iOS - Analyze, Diagnose, and Optimize Automotive Battery Performance of Regular Flooded Batteries, Auto Cranking and Charging Systems, Covering All 12V Vehicles & Boats by Kevin Mckechnie

Update 04/08/2021: Various Autool products seem to be merged into reviews. My rating is for the BT Box, not the 360. My original rating hasn't changed, still 3.5 stars. This rating has more than 3.5 stars, but the device works depending on the operating system installed on your phones. Bought in August 2019 thanks to Scotty Kilmer and when it works with the right phone it works fine. This device does not work with Galaxy S7, but works with iPhone 6, Galaxy S9 and Galaxy S20. I think it's because Android 8 is on S7. I admit that some probably don't pair properly. If you are not pairing in the app by tapping the AUTOOL or BTBOX icon on the home screen depending on the phone while the device is connected to the battery, you should see BTBOX on the screen among the available devices. The Galaxy S7 will be paired and then unpaired when you start testing. I emailed the developer about this, he needs to update the app to make it work with Android 8.
