Yes it works without service. We both use Bullet Flight on iPhones. I can get 3+ days on airplane mode.
Another very good ballistic program is Exbal. We used to run it on Dell Axims (terrible battery life!!!) I also have the Nightforce version of Exbal loaded on a Trimble Recon. Absolutely bulletproof combo. If I were going to Alaska for any length of time, that would go with me for sure! I still bring it for a backup in the truck if the phone goes on vacation
The military version of BulletFlight allows us to use Coriolis and spin drift calcs for the really long shots. Don't need them (for the 338s) under 1200 or so.
We have had no problems with these, but I still recommend building drop charts for various conditions and stashing them throughout your gear...
Also take a look at an ap called Shooter...you can use spin drift and coroiolis calculations. Also hooks up to nearest weather station to make adjustments to drops based on temp, altitude and humidity. Its the only one that I have tested so for all I know all of the recommended aps above might do the same as Shooter but its a very nice setup and works great for my uses.
That will work very well for you. I have my iPhone4 in an Otter box and haven't been able to kill it now for 2 years. I hear the Lifeproof cases are better. Another feature of BF is an option called "calculate simple". You input your atmospherics in the main screen, then click on calc simple. It allows you to scroll distance, wind speed, and wind direction...no typing in numbers! Handy for fat or cold fingers Not sure if Level 1 has it, but the M version does.Awesome thanks for the detailed response sam. Im one of those lightweight weirdos so i plan on using a ballistic app on my iPhone that has a life proof case for all my sheep and mountain hunts so I'm not adding anymore gear. But I'm just getting my longer range setup going in the next couple weeks so can't wait to go build/verify some ballistic charts
It uses 4G, so in order for it to sync with a weather station you have to have cell service. Everything else will work even without cell service.
