Mobile device Applications (apps) Android, Blackberry, IOS (apple) - Hunting ish

A small collection of applications I currently use while out in the 'field' are as follows. 

My current device is an Samsung Galaxy Note 4 running Android 5.x.x - I carry a spare fully charged battery and a solar battery reserve charger for any electronics that might need 'topping up' - couple 128GB Micro SDXC cards too for footage. They are in the wallet.

I also use the "state" applications for hunting regs so I can easily switch over to view what, if any regulations are at a specific area or species, etc. Or If I think what I am doing requires me to have a hunting license and I need to purchase one on the fly. 


Had been looking for an 'Edible Plants' app if anyone has any suggestions. Any other worth while applications I should have in the arsenal?
