# Calculator+ vs Conversion Calculator

The clearest difference is rating: Conversion Calculator at 4.8 against Calculator+'s 4.0. Conversion Calculator also leads on ratings volume (157 vs 1) and update cadence (every 5 weeks vs every 5 months). Calculator+'s advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and device support there is nothing between them.

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

Conversion Calculator holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Conversion Calculator has 157 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Calculator+ ships an update every 5 months, Conversion Calculator every 5 weeks. Both last shipped on October 1, 2026.
