# LED Calc. vs Capacitor

The clearest difference is review sentiment: Capacitor at 100% against LED Calc.'s 50%. Capacitor also leads on rating (4.8 vs 1.0) and ads (none vs shown). LED Calc.'s advantage is update cadence (every 10 months vs every 40 months) and iOS requirement (12.0 vs 26.0). 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.

Capacitor holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Capacitor has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of LED Calc.'s written reviews are positive against 100% of Capacitor's.

LED Calc. ships an update every 10 months, Capacitor every 40 months. The most recent releases landed on June 5, 2026 and September 9, 2026 respectively.
