# LED Calc. vs LED Resistor Calculator Plus

The clearest difference is review sentiment: LED Calc. at 50% against LED Resistor Calculator Plus's 0%. LED Calc. also leads on price (Free vs $2.99) and update cadence (every 10 months vs every 47 months). LED Resistor Calculator Plus's advantage is rating (4.8 vs 1.0) and ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.

LED Calc. is free to download; LED Resistor Calculator Plus costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

LED Resistor Calculator Plus holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: LED Resistor Calculator Plus has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of LED Calc.'s written reviews are positive against 0% of LED Resistor Calculator Plus's, so the app with the better star average is not the one people write more warmly about.

LED Calc. ships an update every 10 months, LED Resistor Calculator Plus every 47 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
