Very poor

I used the old program when it was built by tap logic and was very happy with it. This program crap, half the time when I want to use it it will not sync with the cloud so my fields are not shown. I have sampled fields in the past only to have it lose my data. I received an email from the lab showing my data was completed and two days later it’s still not in there program to review the maps. If you can find another program to use I would do that, it will save you a lot of headaches

Doesn’t work.

Wasted my time driving a field. Went to submit my boundary and it failed. Something about a “parent” something or other.

This app is terrible.

I wish I could just use the old app. This new app doesn’t work at all.
