Army Survival for iPad $2
It’s the classic Army Field Manual, but no sergeant makes you do pushups. Skim by chapter, bookmark essential skills to reference later, and follow step-by-step instructions with how-to illustrations on everything from shelter building to starting a fire with a binocular lens.
Need to set a fractured leg? Skip the trial-and-error and learn how the pros do a field fix with saplings. Gripe: The search function is fine for broad categories (frostbite), but slow when you’re looking for more obscure details.
