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. Neither carries in-app purchases, so what you see is what you pay.
Calculator‰ holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Calculator‰ has 409K ratings behind it against 51K, so its average is the more settled of the two. Written reviews complicate that: 70% of Calculator‰'s written reviews are positive against 78% of Calculator HD Pro Lite's, so the app with the better star average is not the one people write more warmly about.
Calculator‰ ships an update every 4 months, Calculator HD Pro Lite every 2 months. Both last shipped on September 24, 2026.
