Android installer package for ElectroCalc, version 2.7, at 13.4 MB. ElectroCalc is an electronics calculator app, useful at the bench for quick work such as resistor colour codes, Ohm's law, voltage dividers and similar circuit calculations during repair. The .apk format installs directly on an Android phone or tablet once installation from unknown sources is allowed. Since it is a standalone package, scan it before installing and prefer an official store version where possible, as older APKs may not run on recent Android versions.
