Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
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.
Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 1, 2026 and November 12, 2026 respectively.
