I'm not much for apps (barely know how to use my phone) but my buddy installed this app called Time2Hunt on my phone. Kind of like Jeff Murrays moon guide, tells sunrise, fall, overhead, underfoot, temp, pressure, what days will be best and what times of the day will be best for your area. Don't know if its accurate but I'm giving it a try. Figured I'd let people know and see if anyone else has feedback on it?
