Hi All,
Long time reader here, but this is my first post.
For those currently running a ballistics app on their android phone ( free or otherwise ), I just wanted to point out that I've written one that is now available for android. Put a lot of work into this so your feedback (positive or negative) is really appreciated.
As is usual for these sorts of things, I have a free version and paid version.
There are many free options with reduced feature sets, but I'd like to think that none are as nice to use or have as many features as my free version. The main limitations are lack of spin drift, lack of Corliolis corrections, and lack of Monte Carlo (dispersion) analysis.
Every version has "nice" features for a ballistics calculator like the ability to store your rifles and loads, a built in ballistics library with a few hundred projectiles, scope overlays. Scope overlays have correct stadia marking dimensions and thicknesses, they are zoomable using pinch-to-zoom with correct support for first and 2nd focal plane scopes. The scope library is no doubt sparse at the moment but if you put in a request for a scope here I'll do my best to get it in the before your next range trip
You can also do truing of muzzle velocity, even in the free version, to get your drops dead on even at very long ranges.
I tried where possible to add little things that people might find useful. For example if you run a Monte Carlo shot dispersion analysis and your Target is set to an F-Class target, it will run through the shot dispersion and estimate an "average" F-Class score for your setup. It will show that estimate in the solution details (small font area) in the solution tab. Just don't be surprised if your score comes out to something like 188.8-3.6X, that just means for many shots it predicts you'll get within the X ring 3.6 out of 20 times.
I could write more about what it can do, but I think I won't bore you with the details. Thanks for having a look at what I have to offer. Happy shooting.
See below for some screenshots, or just install it to try it out. I'd appreciate feedback and requests if you have any.

Pick a rifle ( long click to edit/copy/delete )
Pick a load (long click to edit/copy/delete)
Here's where you set up your target conditions, like range, atmospheric conditions, etc.
Solution HUD tells you your drop in multiple units, including "clicks" for your rifle's scope. Set the click value of your scope when editing the rifle.
Drop tables
Showing predicted drops (red dots) for a 5.56 pattern rifle to the ACOG drop markers. You'll see in the next image that they match up pretty much correctly, but it's tough to see each drop marker when looking through a 4X scope out to 800 meters.
"overzoom" just means we're scaling the view up larger than the scope will allow. An IPSC target at 800 meters is hard to see otherwise through the ACOG.
Compare trajectories for different rifles/loads
Simulated a bunch of shots from that .223 to an IPSC target at 800 meters
The scope view (from the plot tab go to menu -> Scope View) shows you how to hold assuming you haven't dialed any wind/elevation into your scope.
