While the LabRadar unit itself is nice when you can get it to consistently acquire each shot, the app is just horrible. You can’t do anything without being connected to the unit. So, you’re burning battery while you’re setting up strings, etc. It also disconnects constantly. The only thing you can edit per string is it’s name. Forgot to change the bullet weight in settings? Well, you’re stuck and can’t do a simple edit. For weather conditions, you have to enter manually whereas other apps pull the data from your phone. Switching back and forth between strings fails. When I change back to a prior string on the app, the unit still records to the existing string. For the price of the unit, they really need to fire their app designer and hire someone who knows what they are doing. They need to look to their competitors for good app function. I’m honestly thinking of selling my LabRadar and going back to my ProChrono because Digital Link’s app is light years ahead of LabRadar and was I intuitive and a joy to use. Labradar’s app is just trash and turns a day at the range into a chore.
