Thanks for the new heading. Hope others respond, need all the help I can get using my smartphone.
Found the app "Tool Box (free)" from Google Play for my work.
Has 19 utilities in one place.
- Compass, Leveler, length measuring tool, Protractor, Vibrometer, Magnetic Field Detector,
Altimeter, Flashlight, Unit Converter, magnifer, Calculator, Abacus, counter, Score Board,
Roulette, Barcode Reader, stopwatch, timer and Metronome.
I use the magnifier alot; if I need to zoom in on a motor faceplate and will allow you to take
a picture if you want.
For Android 2.2 and up, and uses 3.0 mb of space.
As stated, it's free and can be downloaded from Google Play.
