Verdict
The clearest difference is update cadence: SMD decoder at every 2 days against Resistor's every 9 months. SMD decoder also leads on iOS requirement (11.0 vs 26.0). Resistor's advantage is ratings volume (17 vs 1). On price, rating, ads and in-app purchases 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.
On the App Store both sit at effectively the same score — 4.9 for Resistor against 5.0 for SMD decoder. That said, the two scores are not equally well evidenced: Resistor has 17 ratings behind it against 1, so its average is the more settled of the two.
Resistor ships an update every 9 months, SMD decoder every 2 days. The most recent releases landed on August 27, 2026 and June 1, 2026 respectively.
