If you want to change a parameter after it has calculated you have to clear everything and put it all in again.

So useful take my word for it. It seems so good to me I would give 5 stars.

you should provide a number input field instead of a generic text input and tolerate floating point values using both dots and commas.

For using E-cigs, this is an Awesome app. I can figure out what volts I need to use with a certain ohm coil. This one works with ONLY 2 of the 4 numbers and calculates the other 2 for you. Easy to use, doesn't take up much storage space, and is quick to use. I recommend this one to all Vapors.
