Needs work
The unit seems to be working well. I have only had it for a few days but it seems very consistent. My complaint is with the app. The app is too basic to be of use. It allows you to store records by date and description. It also can link to your gps to record where you ran the test (although I can’t think why anyone would do that). No sort option. There is no information about the app so you have to figure it out. Poor translation into English maybe the issue. The app button doesn’t say SAVE but is labeled SURE. (I am not joking).
