I don't really have a issue with it mainly I (along with about every one I know that owns a 2400ABS) feel very strongly that the app for it could use some major changes. Like being able to save gun profiles to the cloud, ability to copy gun profiles to make a new gun profiles if you just wanted to say change ammo on the same rifle without having to rebuild a new profile from scratch, be able to disable the phones screen autolock from the app not have to go back through the phones settings. The app has not had one update since it came out I heard that the 2400 ABS could be part of the BDX system with a firmware update. These are just a few off the top of my head . Thanks for reaching out to him I don't mean to sound like a whiny bitch the 2400ABS has performed well for me just seem like there is room for improvement with the app.
