Resistor AI Calculator vs SMD decoder
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Resistor AI Calculator
Point your phone's camera at a resistor to instantly identify its value. Currently supports 4-band carbon film resistors with a 5% tolerance.
- Real-time resistor detection
- Automatic resistance calculation
- Supports 4-band carbon film resistors
- 5% margin of error detection
- Uses smartphone camera

Hold your smartphone over the resistor, and detects the object in real time and calculates the resistance value. Currently, only carbon film (brown) resistors with 4 lines and a margin of error of ± 5% (gold) are supported.
SMD decoder
Decode SMD resistors with this practical tool. It supports three-digit, four-digit, and EIA-96 encoded resistor values, providing quick and accurate identification.
- Decodes 3-digit SMD codes
- Decodes 4-digit SMD codes
- Decodes EIA-96 SMD codes
- Resistor value identification

Verdict
The clearest difference is rating: SMD decoder at 5.0 against Resistor AI Calculator's 3.6. SMD decoder also leads on ads (none vs shown) and update cadence (every 2 days vs every 15 months). Resistor AI Calculator's advantage is ratings volume (5 vs 1). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SMD decoder holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Resistor AI Calculator has 5 ratings behind it against 1, so its average is the more settled of the two.
Resistor AI Calculator ships an update every 15 months, SMD decoder every 2 days. The most recent releases landed on October 15, 2026 and October 30, 2026 respectively.
