What is Reddit's opinion of Vape Tool Pro?

From 3.5 billion Reddit comments

Fantastic app and it's plug and play for ohms law https://play.google.com/store/apps/details?id=com.stasbar.vapetoolpro (check the voltage of your battery quick Google search will do that much for you and you're off to the races if you know the rest)

It's call vape tool pro:

It's amazing. It's got coil calculator, juice mixer, ohms law, sweet spot calculator, battery database, battery life calculator and more.

Its an app for your phone, its called Vape Tool Pro. It has a coil calc, ejuice blender buncha stuff on ohm's law, converters and battery life thing built into it. I mainly just use the coil calc and ejuice blender parts. But its nice, can you can save your recipes for coils and juice, and then you can rate the juice recipes accordingly and put notes on them, so like v1.0 - needs "such and such added for v1.1"

And when you input your flavors, it has how much you paid for such and such ml and calculates the cost per 10 ml. then when you mix up a recipe it'll give you the total cost that your bottle of whatever size you choose will cost.

Its pretty slick. and simple. I think I got it a week ago for 3.49. Not bad at all. worth it imo.

Edit:

I tried to use one of the free juice calcs from the main reddit diy page, but it seemed overly complicated to add flavors and everything to your recipe. that one is super simple.

Sad to say, but someone's already beat you to the punch. And it is an amazing piece of software to boot. https://play.google.com/store/apps/details?id=com.stasbar.vapetoolpro

From the phrasing of your question, I am assuming you mean wraps in reference to coils, due to your secondary question concerning resistance. With that said, as a general rule of thumb, yes, more wraps would produce bigger clouds due to the amount of surface area being provided to heat the juice (more surface, more vape), but only if certain other conditions are met such as the amount of power applied, amount of air supplied, and whether the coils itself can handle such power without burning the juice in the process (ramp up time, as well).

One thing I personally do to help maximize what a coil can produce is using heat flux. Heat flux is basically the heat capacities of the coils in question at a given wattage, usually measure in mW/mm². A good ball park figure would be around 200 mW/mm²...not to hot, not to cold...just a good solid performer. Now to get that heat flux, you either have to build a coil to sustain that a certain wattage OR set the wattage as to not exceed the heat flux for the coil in question. To determine either you would probably need to use the Coil Wrapping or Wire Wizard tabs on Steam-Engine.org...or what I have been using lately which is an app on my phone called Vape Tool Pro(Google store link), which has a sweet spot setting that lets you set the desired heat flux and wattage and it will tell you the resistance needed with the type of build in question...

For example...I have a little DNA40 E-Square that I keep paired with a color matched Goblin Mini. To get the most out of those 40W, I'm looking to build a coil setup that has a heat flux of ~5 mW/mm² per watt, 2.5mm in diameter, in a gauge that will allow me to get as many wraps as I can fit without it touching the chimney sides. After fiddling with the settings, that comes out to about 7 wraps of 26g @ .44Ω which gives me a heat flux of 204 mW/mm² @ 40W...

One other item to factor in. More coils isn't the only way to achieve area. Tightly twisting wires of a smaller gauge will provide more surface area than a single wire of the same resistance. So, 2 tightly twisted 28g wires will come out approximately the same resistance as a single 26g wire, but because of the ribs/ridges in the wire due to the twisting, will provided more surface area and performance (vapor production and flavor) than the single wire....plus juice wicks to the coil better.

Called " Vape Tool Pro" there is a free version but it doesn't have as many options.

This is really great too.https://play.google.com/store/apps/details?id=com.stasbar.vapetoolpro&hl=en_US

No worries!

You can use a single coil on a dual coil RDA. See this post for the Drop RDA. With that, it is good to use a coil calculating tool to help in setting up everything safely. I use Android with the Vape Tool Pro app. It is quite handy. There is also Steam Engine.

More specific to your needs/wants: My preferred dual coil build is a 2 x 28g N80 core & 36g N80 wrap. 3.0mm ID 5/6 wraps. Should come out around 0.22ohms with a working range of 50-75W. (it can go much higher on wattage, but starts to creep beyond the 20A max I prefer. I'd likely settle around 60W, but that is subject to change as I vape :) )

So many factors go in to what is "good", but as droll as it sounds, safety is number one!

May not have looked to hard. VTP has been my go-to for quite some time. https://play.google.com/store/apps/details?id=com.stasbar.vapetoolpro

What app are you using? Is it Stanislaw Baranski's https://play.google.com/store/apps/details?id=com.stasbar.vapetoolpro

Really neat app called vape tool pro Does all the math for you, for example I plugged your coil in and it should be run somewhere between 20-40 watts. They also have a free version but I believe it has ads and only basic coil designs.
