Important notice:

The Steam Engine web site now supports the "add to home screen" function in Android and iOS. Read more about how to activate this feature here:

This new functionality makes this Android app nearly obsolete. You're still free to purchase it if you want to support Steam Engine financially, or if you want an ad free version with somewhat limited functionality, but you should know that the development of this Android app version of Steam Engine will be abandoned, after which no further updates will be released.


Welcome to Steam Engine Pro, a suite of calculators for your vaping endeavors: Building coils, checking battery drain, mixing e-juice, and more.

The Ohm's law calculator is a simple Ohm's law calculator with Joule heating.
The coil wrapping calculator is specialized for winding coils for rebuildable atomizers (RBA).
The battery drain calculator shows you the current and power drain on the battery in your e-cigarette.
The mod range calculator tells you the optimal resistance range for your regulated mod.
The DIY e-liquid calculator lets you select nic strength and VG/PG ratio for the nicotine base liquid and your desired outcome.

Supports offline use. No ads.
