The whole system, microphone and tablet seem to work fine but theSetting and instructions are worthless. It is a very difficult system to Set up. Very poor instructions and their web compatibility with the microphone stated it would work with an iMac M1 chip when it did not. Had to call the manufacture to find out they made a mistake. This device is NOT user friendly at all.
You need the sensor

I've read you can use your headphone/mic from your phone. Sadly, this is not the case. You can buy their sensor, but it's still cheaper to buy a real timegrapher.

I have had this device for ten months. It worked well with my iPhone until I upgraded to iOS 18. The device no longer functions with my iPhone. I have to connect it to my iPad which is running iOS 17.7. Either don’t buy the device or don’t upgrade your operating system. I contacted the developer and they suggested I cal Tim Cook! Worthless
Issues iOS 18
