Ive been using this for almost 3 years. Make sure that info you are plugging in is accurate and you will be on the money. Several times things didnt jive and my bullet was not landing as predicted by the app. I rechecked my settings and realized that I made some errors in the data entry. As soon as I corrected my data input it was right on target accurate. Temps are not always correct. I always bring my portable weather station with me. Ranges can be hotter or colder, wind stronger, etc. than the nearest weather station were this app gets its info. Double check your weather readings against your hand held weather station.
