Overall, the app is extremely useful, but it is lacking in one area: Compound cam type. Seeing as how the cam shape makes the difference between one spine of arrow and another, I'm disappointed to not see a feature like that implemented. Seeing as I'm a recurve shooter though, I'm otherwise happy with how the app performs for my needs!

Thanks for your positive review and your comment. As you pointed out correctly, the cam shape can and does make a difference. But instead of using some descriptive term on cam shape, like round, soft or hard, which still doesn't exactly factor in what the cam does to the spine, we chose to go with the ATA speed rating of the bow instead.

If you want pretty arrow pictures this is the app... But only if you buy the upgrade to unlock all the arrows The previous version was much better in offering a readable table of arrow spines... But why have it all on a single swipe table when you can scroll down for hours The one star is for the drawlength and draw weight selection bar which is usable

Thanks for your review. We've worked hard on the drawlength and drawweight selection bars so we're happy you like them.

Good but some flaws. I get some "invalid" spine for anything above 69.4 lbs. This App should be able to handle not so uncommon bows such as the Phase4 at 75lbs.
