Coil Calculator

There should be options to switch each category from metric to awg Plus you should add fraction of an inch to the diameter selection other than that its ok and pretty accurate        Ok

Not a bad app but needs nickel wire for the DNA 40s        Needs nickel wire

Very vague Just calculates resistance Doesnt tell you how many cool wraps If you have an ohm meter Youre better off This app is junk     Crap

Bad interface design Not localized well Accurate within the tolerance of the values           Bad Effort

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

A little confusing as to what all of the numbers are actually changing with your build Also try adding aftermarket wire royal gplat arsenal hotwires etc           Cool but confusing

Just downloaded this apponly played with it for a few minutes and already see things that need improved Such as the second wrap count maxes out at 9 while the first goes all the way to 20 Also the lead length could be a little more straight forward Still not sure how to use that feature Maybe when improvements are made this app will get 5 stars iPhone users are looking for something like vapers toolbox        Needs improvement

Definitely not user friendly and very little instruction Having a hard time figuring out how to just say I have a particular gauge wire how many wraps of it do I need and around what size diameter I should be making the coils Not sure what the second column numbers are either Not labelled or explained very will Maybe be able to figure it out with some time but right off the bat not very useful     Very confusing app

Not good at all Confusing interface and not worth the 99 centsWish i could return it     Confusing and Garbage

Not enough explanation Better apps out there        Confusing

Switching between decimal and millimeter was helpful for me Its definitely worth 099 Biggest challenge I had was understanding the input boxes after the comma are decimal places We yanks use periods Im happy with it and thank the developer for taking the time to create the app Its definitely easier than looking up wire resistance and doing the calculations by hand              It Works and is Useful

Looks great but need an info page and when switching from AWG to metric the coil name and category changes example I select Kantal 20 AWG then switch to metric and switch back to AWG the category changes           Little imprecision

App might be worth something if the layout was more descriptive about the information they require for calculationsso I cant say if this is a good app or a bad appI only wasted 99 on it        Hard to Understand

I love the idea and hope for a similar app to the Vapers toolbox in google play                 Needs better instruction

Add ribbon wire Add twisted coil provide suggestions for desired ohms Add pics maybe tutorials than charge 5 for it           Great idea but

There are not enough labels in the app And the directions need to be improved This could be a really useful app for the beginner and for the shop owner as a reference guide The lay out instructions and labels just need to be improved        Good concept execution needs help

Would like to see diameters in decimals and would be nice to have labels on the values to describe what your inputing so the app will function properly     Needs work

This could be an awesome app but it is too confusing and has no kind of instructions or documentation     Needs instructions

Ok app it needs common drill bit sizes instead of AWG for interior size           An ok app needs more options and a facelift

Please allow for awgmetric selection and inchmetric wrap diameter selection for folks that use awg wire and metric wraps Thanks           Almost there

Great app I will use it often i would give it more stars if the interface was easier to understand once i figured out the logic it made sense Thank you           Helpfull app

This app has potential but theres 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 dont know the first thing about electricity amperage or resistance Maybe they shouldnt 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 Im 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           Could be 5 stars but
