What if you are a country bumpkin with no iPhone or Android phone....... cause the cell service sucks? Is their a downloadable version for a Mac desktop? May be on there and I missed it. Power has been flickering and I keep losing the internet so gave up tying to surf around the site.

Then you don't use a ballistic program. You use ballistic tables.

For the phone challenged, JBM Ballistics is web based and is probably the best out there.

If you look at the downloads page on JBM, Ballistic XLR is a free spreadsheet based app that works well.

Ackely Improved User was pumping Advanced Ballistics; he said for $20 how can you go wrong. Good point, so I followed his advice. While the wind feature is overly complex, in short I love this thing, proving sometimes you just got to listen others.

I use the JBM app on my laptop; very good as well.
