Verdict

The call

The clearest difference is review sentiment: Conversion Calculator at 100% against Convert's 60%. Conversion Calculator also leads on ratings volume (165 vs 1). Convert's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Convert sells 2 one-off in-app purchases and Conversion Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Convert holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Conversion Calculator has 165 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Convert's written reviews are positive against 100% of Conversion Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 1, 2026 and November 12, 2026 respectively.
