Porting programs

[Mc2Stroke]

I have seen a few porting programs/ software, most are pretty expensive, more than the average person would want to spend but there are a few affordable options like “Porting Calculator v4.2” I also saw a mobile app called “2 Stroke Porting” I downloaded it on iPhone App Store, I wasn’t able to find it when I looked again a few days ago but I believe I saw it on google play store for Android.
Has anyone heard of either of these? Or used them? I will try and take some screenshots of the porting calculator I downloaded on my phone.
Is there any other affordable or free porting tools people are using?

Free Porting Programs for everyone!

Heres a couple of porting programs i thought might be beneficial to anyone interested. The links are user guides for the porting calculator and port map analyzer. The exhaust calc should be pretty self-explanatory if you figure out the other 2, lol. Enjoy...
