What is your favorite ballistics calculators?

I'm looking for a calculator that is very specific where you can add in your barrel length, caliber, bullet weight, shape, primer type, amount of primer, sight height, and of course the range that your shooting across to find out what amount of drop would be at that range. I'm not a math genius so i think it would be hard to learn a formula to something like that. The reason i said barrel length is because i don't have a chronograph to check what the velocity would be with that round especially when switching in between barrels. If there's one that i could download to my pc, view on the internet, or for ipod touch/iphone. I could make a chart if it's for pc or on the internet and print out basics and all.

How to block my school from reading my messages?

So my school has free Wi-Fi, but it downloads something to my iPhone called a 'provisioning profile.' It lets you use your phone normally, but last week my friend got called to the office because he was iMessaging another student about a test. (No cheating.) Apparently the school can track EVERYTHING you do on your phone with a provisioning profile. I would use LTE, but I get no service in school, and at times I need to text my parents in class or lunch. So my question is, how can I stop my school from reading my messages, and does the provisioning profile work outside my school's Wi-Fi, or is it only when I'm connected to it?
