The app is easy to use and it works

I’ve had the app for a few weeks now and every time I’m able to connect to it and make the adjustments needed. I can’t speak to the issues others have mentioned since I haven’t experienced any. Overall it works great no complaints here.

Great potential but needs work

Let me just start by saying I own the GHL doser 2.1 & it is a wonderful, accurate dosing pump.... but The mobile app is totally unreliable... more often than not it will fail to connect to my doser even though I have top-of-the-line Internet service and great Wi-Fi signal... every time I contact GHL customer service they politely explain that the GHL Connect Service is temporarily down... that’s totally understandable if it happened every once in a while… But this seems to be almost a monthly thing...
