Comments on Resistor Scanner for Android

★★★★☆ Corey McCormick · Feb 15, 2026

Overall it seems to work but takes very specific lighting. Using an S22+ the flash creates glare that confuses it. A sheet of black EVA foam, construction paper or felt reduces the glare and improves the contrast. Link to upgrade and remove ads would not work. Just got it, so I don't yet know about long term. 100ohm vs 220ohm detection worked mostly if the light was good and the zoom was larger. The more focused zoom the better so far. That makes sense as it has more pixels to work with

I like this app so much I have no multimeter, but it scans resister properly and ohms are correct

★★★★★ Ronnie D · Aug 18, 2025

Liked the app. 8 out of 10 times it shows the correct resistance value from the color codes. Helpful for those who are colorblind or sometimes even colors printed on some resistors have slightly different hues. I mainly liked the zoom and exposure sliders provided on the app screen. It would be nice if color hue adjustment could be added for using under yellowish fluorescent light. Although the app is too big in bytes it's good enough.

Reads wrong colors. Tried settings but not help.

★★☆☆☆ Jakub Scepka · Jul 27, 2025

Unfortunately it doesn't work, the camera image is bad, the white balance is totally off. Values totally wrong. Uninstalling

★★☆☆☆ Dan Wilson · Jan 1, 2023

Sorry man, I wanted to give this tool a real good try, but I could never get it to detect the correct value on any resistor. I tried various white balance settings, brightness, etc. Nothing worked. Most of the time, the main problem is that it never detects a brown band properly. It always reads it as black. I tried different backgrounds as well, and also tried both 5% resistors (beige body) and 1% resistors (blue body). Also tried manual specifying the number of rings. I love that you tried.
