Number 1 accessory to improve Accuracy beyond 50 yds?

Which ballistic app are you using? Id like to calculate the hold over for 75 and 100yd. If I could hit a spoon at a 100 now that would be impressive, at least for me.
That graph is Chairgun. Its obsolete but it works great for quick calculations to get an idea of something. Like others have mentioned, Strelok Pro is my go to for real data.
