# Resistor Code Calculators vs SMD decoder

The clearest difference is ads: SMD decoder at none against Resistor Code Calculators's shown. SMD decoder also leads on update cadence (every 2 days vs every 7 months) and iOS requirement (11.0 vs 13.4). On price, 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.

Resistor Code Calculators ships an update every 7 months, SMD decoder every 2 days. The most recent releases landed on September 17, 2026 and October 1, 2026 respectively.
