Solenoid Comparison App

This is an Android app that compares the force, resistance, and power of two solenoid coils.

You can use this, for example, to determine how much additional force you can get by removing wraps, and how much extra power that will cost. Or to investigate possible solenoid substitutions in your coin op machine.

The app is digitally signed, but not available on Google Play, so you'll need to allow installation from unknown sources to try it. To do that:

Android 5: Settings->General->Security->Unknown Sources

Android 6: Settings->Personal->Security->Unknown Sources (Security might also be labelled "Fingerprint & Password")

You can then visit this page on your device and press the link below. Once it downloads, tap the "download complete" notification and select Install.
