# Arc Flash Label Calculator vs Arc+

The clearest difference is rating: Arc+ at 4.6 against Arc Flash Label Calculator's 3.8. Arc+ also leads on ratings volume (113 vs 4). Arc Flash Label Calculator's advantage is update cadence (fortnightly vs every 4 months) and iOS requirement (9.0 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Arc Flash Label Calculator sells 1 one-off in-app purchase and Arc+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Arc+ holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Arc+ has 113 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.

Arc Flash Label Calculator ships an update fortnightly, Arc+ every 4 months. The most recent releases landed on October 6, 2026 and October 8, 2026 respectively.
