Resistor Color Code Reader
Read full descriptionHide full description
Read any resistor in seconds. Tap the bands as you see them on the component and the value appears instantly, with its tolerance and the range the part is actually guaranteed to fall in. Type a value instead and the app shows you which bands print it. FOUR, FIVE AND SIX BANDS A 4-band resistor carries two significant digits and a 5-band carries three, so the same colours mean different things on different parts. Most apps quietly assume one format. This one asks, and switching between them keeps the value you already have. GOLD AND SILVER ARE MULTIPLIERS TOO Not just tolerances. Without them every sub-ohm resistor is unreadable, and a surprising number of calculators cannot read one. THE BENCH TOOLS Unlock surface-mount decoding for 3-digit, 4-digit, R-notation and EIA-96 markings โ including the one genuinely ambiguous case, where the app names both readings instead of guessing. Snap any value to the nearest E6, E12, E24, E48 or E96 preferred value and see how far off it is. Add up a handful of resistors in series and in parallel. WRITTEN THE WAY YOU WRITE IT Type 4k7, 4.7k, 4700, 470R or R47 โ all of them parse, along with a comma decimal mark and Arabic and Persian numerals. NO ACCOUNT. NO INTERNET NEEDED. NO TRACKING. Everything is calculated on your phone. Nothing is uploaded anywhere, and the app makes no network requests at all.

Verdict
The clearest difference is in-app purchases: OilTrack at none against Resistor Color Code Reader's 1. OilTrack also leads on update cadence (every 11 days vs every 4 weeks). Resistor Color Code Reader's advantage is iOS requirement (16.4 vs 26.4). On price, ads and device support there is nothing between them.
