# ElectriCalc Pro vs Arc Flash Label Calculator

The clearest difference is rating: ElectriCalc Pro at 4.9 against Arc Flash Label Calculator's 3.5. ElectriCalc Pro also leads on review sentiment (78% vs 50%) and ratings volume (364 vs 6). Arc Flash Label Calculator's advantage is update cadence (fortnightly vs every 10 months) and monetization model (free vs free with in-app purchases).

Both are free to download. ElectriCalc Pro sells 2 in-app purchases, starting at $4.99 per month and Arc Flash Label Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
