As an outfitter and professional hunting guide who operates year round, I really hoped that this solunar stuff would be a serious tool. I spend roughy 240 days a year in the field and Im in the ranch about 320 days a year. So, my opportunity to test out this app is better than most hunters. Unfortunately, at best, it may give you a SLIGHT indication of when youll see more activity; but I hate to even go that far. Ive had top rated days produce virtually zero game movement and low rated days where game was everywhere. This is not to say that some good days were as advertised and so were bad days. The point is, I cant place ANY trust in these charts when planning or anticipating a hunt. Weather forecasts and traditional moon phase analysis is 1000 times more accurate and dependable.
The science behind it, I believe, is sound; but I think its such a MINOR influence, compared to so many other factors, as to be virtually useless for hunting. Ive had better luck with it for fishing - the sun and moon have a much bigger effect on bodies of water so it only makes sense that it would effect fish heavily. However, its sure been wrong plenty of times - right along with other solunar charts Ive tested.
Bottom line: I would NOT recommend this app for hunting but its OK for fishing. Its only $5 so its not going to break the bank but dont buy it expecting to seriously up your game - its nothing but a toy wrapped in shiny paper.
