I've been using this app for years. But do yourself a favor, write down all of the pertinent info on each of your rifles. I had a phone that simple died a few years back. I mean absolutely nothing...the parrot was dead, deceased, no more! Had to get a new phone and install everything. Fortunately I had some (but not all) of my photos and such in the cloud and was able to retrieve them. The next day I picked up a new phone, added the App, and pulled out my handy notebook full of my DOPE. Velocity, bullet data, scope height, etc. I grabbed my favorite rifle and was up and running in no time. Later that evening I entered all of the data for my other rifles in just a few minutes. No having to check velocities, measure scope heights, all of that nonsense. Had it all at my fingertips. Technology will fail you sooner or later. But the written word is there forever. Well, unless you lose it.
