I am still a newbie using the app. I ran into a conundrum at the range last week. Quantum would not update in the HUD no matter what range I inputted. I defaulted to iStrelok to make it though the day. This morning, I was checking the settings. I have it installed on 2 iPhones and my iPad. I synced my profiles to the cloud--everything looked the same but the iPhone that I used at the range still did not calculate. (Elite version if that matters). I deleted the app and reinstalled. Interestingly, I did not have to login again--it connected automagically and pulled my profile in (including one that I thought I had deleted???). It is now working. I'm bringing all three to the range today, just in case.

Each time I go, I experiment with one feature. I don't want to change too many things at once.
I am not quite ready for the expense of a Kestrel. Naive question--why would one need a solver in both the Kestrel and the app?
I have a Tempest WEATHERmeter for Shooting bluetooth device for local weather data. I enter the data manually but would love to see it integrated with Quantum if possible. It pretty easy to use. I compared the readings with my Davis station at home and they matched.
Happy Father's Day to all the dads out there....
