Coil Building App?

[Smthng2Do]

I'm wondering if anyone has seen an app released for coil building gor the iphone? I've seen ohms charts & such. I want something I can input my wire size & desired ohms so it will tell me "Diameter & number of wraps" NOT length of wire. Someone must have made one?? I primarily build microcoils using cotton. I have only doing single coil builds. I like 1.0-1.4 ohms. Don't like it so hot it's fresh out of the oven. Just warm. Vapor & clouds are nice, but I'm into the flavor. Recently got a kraken I want to build dual micros with cotton. Now, it's my understanding that dual builds cut the ohms in half... So, 28g kanthal.. I want my completed micro dual build to be 1.0-1.2/1.3/1.4 ohms. Anyone tell me the diameter & number of wraps to accomplish this?

There is this app, but just downloaded and still figuring out how to use it. A few beers in doesn't help either.

Saw that & appeared it still relates to the length of wire you cut, right behind ya on the suds!

Rest of the apps I have seem are like you mentioned were length of wire. If you download "numbers" there was a kanthal coil calc posted somewhere too.
