Perfect for sub 12ft/lbs air rifles
This app works and is pretty simple to see where the pellets supposed to land and at what range. Nothing too technical and also user friendly (unlike some more “too technical” apps). The rest comes with practice on the range and a well zeroed scope. I would give 5* if you could drag across the trajectory line in 1/2 mills but you do get the general shot trajectory mill by mill, little bit of guesstimation needed and practice to be acurate. Hell every rifles different :)
