APP and Device will not work if you are enrolled in the Apple Beta Program

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

OneOf Accumotion

The whole system, microphone and tablet seem to work fine but the
Setting 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.

No istruction

No way to find out how to ise this app

Crappy app demo mode

Fake app demo mode, doesn’t work, looks like you have to buy hardware for this to work. So it fakes it. So lame.

Help

Doesn’t work for me, no videos on YouTube to help explain 😒

Garbage!!!!!

Completely junk!! $600?!?!? MF!!!

Response from developer

These are professional tools, mostly dedicated to the Swiss watchmaking industry. Please remain polite.

What a rip-off!

Just buy a real timegrapher for a small fraction of the money.

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.

Played with this and it seems to work!!

I know it says you need a special type of device, but I plugged in my headphones and used the mic and placed it behind my watch.... I Had a pretty good idea if I’m tracking it every day how fast or slow my watch runs. This app pretty much Verified the exact deviation that I was calculating myself simply by tracking it on a day today basis. I was also amazed by the magnetism detection... at first I thought “no way” but then I held one of my headphones up to the back is my phone (magnet from the speaker in it should detect a difference) and the thing went nuts! I don’t know how useful it is for long term tracking or actual data collection, but it seems pretty accurate to me. Better than paying for another app! Give it a try!! It’s free!

$600?!???

Don't even think about DLing this app unless you have $600 for the sensor it NEEDS, to make it work. Yes that's right, $6-HUNDRED--DOLLARS!!!!!!!! Ho-LEE-$&#%. Where's the minus stars rating tab?!?
