Trajectory tool

[Mosin Marine]

I have a much older friend who is not very phone savvy.    Is there any trajectory tool that is made for a PC that is similar to ChairGun?

You ARE aware that ChairGun has a MS Windows version and a MAC version, right??
The phone/tablet versions are derived from the PC version.

The Windows version can also run on Linux with Wine.

I had no clue they did, thank you!
