After making the Magic Caliper iOS App in early 2020 I received a number of requests to make an Android version. I’m happy to report that version will release very soon. When it’s available, you can view the Android app on the Play store here. The Android app currently does not have the logging capability of the iOS App. If that’s something you’d be interested in seeing in the Android App as well, please let me know by contacting me at the email address below.
Note: Magic Tech, the makers of MAG-ic Probe are no longer making the Bluetooth Low Energy (BLE) version. The new version works only with WiFi. If you own a version of the probe purchased after April 2021, it is likely the WiFi version. The two probes look nearly identical, but the WiFi version has a small push button switch located near the USB connector, the BLE version does not have this switch.

You can see some screenshots (in regular and dark theme) below:

How to start using the app:
- Install the App on a compatible device. Get your MAG-ic probe ready to begin calibration with one of the magnets that comes with the unit.
- For best results, leave the MAG-ic probe unpowered until you start the app. The reason for this is that the MAG-ic probe will only connect to the phone within 10 seconds of being powered on. Open the app and it will automatically start looking for the MAG-ic Probe.
- Power on the MAG-ic probe. The app will discover the device and connect.
- Next, you will be prompted to begin calibration. When prompted, attach your choice of the two magnets.
- The calibration process will continue. Leave the magnet attached and held away from any interfering magnetic fields. When prompted to do so, remove the magnet.
- The final calibration step will finish with no magnet. Again ensure that the MAG-ic probe is held away from any interfering magnetic fields and at least 12’/30cm from the magnets.
- Once calibration is complete, the screen will automatically go into measurement mode. The app supports both portrait and landscape modes. As well, the screen will be prevented from going into power-saving mode while measuring. Loss of signal, or powering off the MAG-ic probe will cause the application to provide a Time-out warning. The app will go back to searching for the MAG-ic probe and the calibration steps will need to be repeated when the device is found again.
Help with the app:
- The app communicates to the probe when the app is active on the screen. You can switch applications and return but doing so during connecting and calibration is not advised.
- The app is designed to reset to the start should the MAG-ic probe signal be lost. However, should the app get stuck waiting for a response from the probe, you can exit and restart the App. You will likely need to remove and re-apply power to the MAG-ic probe in this case. The MAG-ic probe firmware requires that it go through a calibration sequence every time it is powered on.
This app requires Android version 4.4 “KitKat”, if you purchased or updated your device in October 2013 or later, this app should be compatible.
Android requires that Apps that use Bluetooth Low Energy (BLE) be granted location services. The first time you use the App it will request access location services. The App does not record or communicate your location in any way.
