Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
