Verdict
The clearest difference is review sentiment: Kalkyl at 75% against Calculator Plus Pro's 36%. Kalkyl also leads on update cadence (every 5 weeks vs every 7 months) and ratings volume (714 vs 33). Calculator Plus Pro's advantage is rating (4.9 vs 4.5) and monetization model (free vs freemium). On price, ads, in-app purchases and device support 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. Kalkyl sells 1 in-app purchase, starting at $4.99 per year and Calculator Plus Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Calculator Plus Pro holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Kalkyl has 714 ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 75% of Kalkyl's written reviews are positive against 36% of Calculator Plus Pro's, so the app with the better star average is not the one people write more warmly about.
Kalkyl ships an update every 5 weeks, Calculator Plus Pro every 7 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
