Fake Strelok
This is a wannabe Strelok. The true Strelok is still sanctioned. This person is just trying to throw out a poor copycat app to bait someone unknowingly into paying and stealing their data.

Nice small tool
Not QuickLOAD
This is a low effort copycat app, and is not affiliated with the official QuickLOAD ballistics tool. It doesn’t even have a real internal ballistics simulator - this app seemingly just does linear interpolation between (presumably) published datapoints.
