tCheck

I would give this 0 stars if I could. For nearly $300, this thing is absolute trash compared to the original model. The idea of running an app-based spectrometer is asinine and the app will not give a proper reading, always owing to "electronic interference" even in a room where the only two electronic objects are the tCheck2 and the phone required for it to work. I am hoping I can find a used tCheck1 and eat my losses... Buyer beware.

There's no way to exit the app. It would be nice if they had some way to double tap back to exit or even just an added feature to select "exit" the app. I have to go into my app settings, then search for it and force the app to close, just to close the app. Other than that, it's great and really easy to use.

Only used to test bho concentrates, seems pretty accurate compared to the Sage machine. I've tried but cannot replicate the issue the really bad reviewer mentions. The app seems stable, no crashes so far. You can add info, extractors name, strain etc but I'd like to have it shown on the main result screen, id like to be able to select any of the history and it bring up main result page.
