# Resistor color code calc vs SMD decoder

The clearest difference is ads: SMD decoder at none against Resistor color code calc's shown. SMD decoder also leads on update cadence (every 2 days vs every 3 months) and monetization model (free vs ad-supported). Resistor color code calc's advantage is ratings volume (5 vs 1). On price, rating, in-app purchases and device support there is nothing between them.

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 — 5.0 for Resistor color code calc against 5.0 for SMD decoder. That said, the two scores are not equally well evidenced: Resistor color code calc has 5 ratings behind it against 1, so its average is the more settled of the two.

Resistor color code calc ships an update every 3 months, SMD decoder every 2 days. The most recent releases landed on September 21, 2026 and October 1, 2026 respectively.
