When the app is working it does a decent job. However, I’ve been trying to logon for 2 days now and can’t, it keeps telling me I have the wrong phone number format and after trying several times and with my email I still can’t get on. I love my NX4G gauges but if NAVAC wants to compete with Fieldpiece they better step up their game on the apps.

Not only is this app full of bugs and glitches, it is plagued by its uselessness in its inability to stay connected to the wireless tools you’re trying to use. The interface is at, first glance, simplistic enough to figure out, but users will soon learn that it’s anything but. My combination, wireless probes and clamps once connected, there would be a tab specifically for that group of four tools, and for some reason, there would be a separate individual tab for one of my clamps or probes, but not the other one opposite of it. Should consider giving the user of the ability to move the tabs and order they want.Removing a tool to try to reconnect, it is a redundant process because it just keeps popping back up under connected devices. When I go to connect to my device and for whatever nonsensical reason, it’ll disconnect after a few seconds. So I go to try to delete it to re-add it (which I shouldn’t have to do as often as I have) even though I get a confirmation that it was deleted, it still shows back up and it’s connected. Navac, fix your freaking app. This thing has a rating of two stars for a reason. It‘s more broken than any app I’ve used so far. When we buy your products, we don’t just pay for the tool. We’re paying to use a workable app to compliment that tool and so far it is not delivered.

The app is bit unstable and only runs perfectly smooth when I’m not in a hurry. The firmware updates for tools hardly ever work and will update one probe but not the other.. But yet I love Navac tools so I’m trying to hang in here and be patient.

Paid $430 for the smart probes and this app nor the probes will display SuperHeat or Subcooling. In addition you cannot see the temp probes and the gauges at the same time. You have to select one tool at a time and then manually switch back and forth. I wouldn’t have released this product until these bugs were solved. I’m returning my probes and going somewhere else. I’d suggest the same if you like efficiency. Good Luck. Btw they don’t display together in MeasureQuick app either.
