So the zealautowerks compression calculator was a bitch to use on the Iphone browser and there was no native app available, unlike the one for Android made by Peter Lintszer.

I've created it over a weekend and it currently has feature parity with the online calculator. Over the coming week, I'll be adding in data for all the off-the-shelf piston and rod options for B,D,F,H and K series engines.

Have at it. It's completely free with a single ad on the bottom. Click on the ad once in a while if you want to thank me.

Share/rate it if you like it. Any suggestions/fixes welcomed. Cheers.
