You need to achieve more advanced level in the vaping electronic cigarette.
and need to build your great and the own coil.

Some questions are still there:
- which wire type to take and what AWG?
- how many rounds do I need to make for a certain resistance/Ohm?
- what if I need to switch from AWG to metric or back?

You can get these answers and more with the help of this small app!

Just select different type of wire and simulate your scenario - answer will be promptly shown. All you need to do after this - just finish the coil assembling!

After you are happy with your new coil, you can always try some other wire, resistance etc

Also, watch for new features coming shortly!

This application takes calculation/mathematic driven approach - please make sure that no shortcuts occurred during the assembling,
Using of Ohm meter device is up to you.

Vaping, smoking etc is just up to you.

Could be 5 stars but


This app has potential but, there's no instructions on how to use it. Or limited instructions. They say this is for the beginner, people who what more info about vaping but, the instructions are very limited. I bet there are many people out there who don't know the first thing about electricity, amperage or resistance. Maybe they shouldn't be building coils but, you know they will. Anyway, you just fill in the blanks and you have your resistance and how much wire to cut for your coil. That way you can see different options for wire type like kanthol a or a1 or many others, and wire size (awg) so you know what to use for a certain coil resistance and how much wire to cut. I'm just not sure what to put in a couple of the fields. A little more description would be great. I would rate it at 5 if I knew what they wanted in a couple of the fields. Please explain.



Very inaccurate. Used for many builds and calculations are way off. It's a nice app and easy to use but if it's that far off on accuracy I'll just stick to the ermeso coil toy. At least I know it's right on the money every time without fail. Maybe this app will improve to make it worth using soon. Thanks.

Want a refund


Trying to find a coil calc that I can use at any time. This isn't it. Seems more like a guessing game than any kind of info/help. There's no instructions or guide. You go in just automatically know what you are supposed to adjust to get what you want.
