Vape Helper

Simple app to calculate volt, ohm, watt and current for electronic cigarette mod setups.

Select the fixed value on one slider (this will typically be the resistance of your coil), lock it and slide one of the other ones to adjust the value (probably power) to your liking and read the resulting setting (most likely volt for v/v devices).

The app also tells you the current draw under those conditions. This is helpful safety information for sub-ohm / mechanical mod setups.
