Verdict
The clearest difference is price: Mathway at Free against Calculator ∞'s $5.99. Mathway also leads on ratings volume (425K vs 6.3K) and update cadence (every 4 weeks vs every 2 months). Calculator ∞'s advantage is ads (none vs shown) and review sentiment (75% vs 51%). On in-app purchases, monetization model, chart position 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
Mathway is free to download; Calculator ∞ costs $5.99 up front. Calculator ∞ sells 4 in-app purchases, starting at $3.49 per month and Mathway sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Mathway holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Mathway has 425K ratings behind it against 6.3K, so its average is the more settled of the two. Written reviews complicate that: 75% of Calculator ∞'s written reviews are positive against 51% of Mathway's, so the app with the better star average is not the one people write more warmly about.
Calculator ∞ ships an update every 2 months, Mathway every 4 weeks. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
