Works on Nexus 6 Feature request, to add acoustic report info would be cool, to capture dB info. I shoot suppressed, and acoustic info would also be helpful when working up subsonic loads. Even with supersonic loads, the report dB would be cool as well.

How about BlueTooth module? Any chance of releasing an add-on BT module (like what Competition Electronics is about to release for the ProChrono) that would connect to this app? Or opening the API in the app to allow users to build their own (several have been made for the ProChrono, using a plug-in adapter that goes from the 3.5mm serial port to BT). I would think that with working USB on the Caldwell unit, connecting a BT module should be fairly simple. Also Drive or Dropbox backup and Excel exports are much needed.

Was working but not now When I bought the chrono I tested it at home (with airsoft) to check it connected to my phone and all was well but today I took it to the range for some reload data and it just wouldn't show any figures on the app, it kept saying synced but just couldn't get it to work no matter how many different ways of connecting it up, the chrono showed the figures on its screen so Now i'm wondering if it's because my phone updated to android version 5 the other day (Galaxy S5) and maybe the app is no longer compatible

Have only tried with airsoft to test so far. The app is a great way to record my shooting data, I'm looking forward to getting to the range to test my handloads. My only criticism is that the app didn't come with very clear instructions other than connecting the phone. I also noticed a feature to record target data and haven't figured out how to add that just yet.
