Its not the best, could be better

Ive read and seen a lot of survival guides and this one has a few useless chapters that are just too broad and or can be overlooked because they dont offer too much usefulness. It also lacks diagrams in certain chapters. I dont think the app is worth $1.99, maybe 99 cents. I could be picky but I think your better off getting the SAS Survival Guide, but thats overpriced.
