# Calculator vs eCalculator

The clearest difference is in-app purchases: Calculator at none against eCalculator's 1. Calculator also leads on ratings volume (916 vs 156). eCalculator's advantage is update cadence (every 3 months vs every 13 months) and iOS requirement (11.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. eCalculator sells 1 one-off in-app purchase. Calculator asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Calculator against 4.6 for eCalculator. That said, the two scores are not equally well evidenced: Calculator has 916 ratings behind it against 156, so its average is the more settled of the two. Written reviews split almost evenly too, at 80% and 80% positive.

Calculator ships an update every 13 months, eCalculator every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
