# Resistor AI Calculator vs SMD decoder

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.

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.
