# Conversion Calculator Plus vs Scale Conversion Calculator

The clearest difference is in-app purchases: Scale Conversion Calculator at none against Conversion Calculator Plus's 1. Scale Conversion Calculator also leads on ads (none vs shown) and review sentiment (100% vs 70%). Conversion Calculator Plus's advantage is ratings volume (15K vs 4) and update cadence (every 2 days vs every 5 days). On price and device support there is nothing between them.

Both are free to download. Conversion Calculator Plus sells 1 in-app purchase, starting at $9.99 per year. Scale Conversion Calculator asks for nothing beyond the download.

Conversion Calculator Plus holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Conversion Calculator Plus has 15K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 70% of Conversion Calculator Plus's written reviews are positive against 100% of Scale Conversion Calculator's, so the app with the better star average is not the one people write more warmly about.

Conversion Calculator Plus ships an update every 2 days, Scale Conversion Calculator every 5 days. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
