Verdict

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.
Uno Calculator holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Uno Calculator has 116 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 73% of Uno Calculator's written reviews are positive against 78% of Calculator's, so the app with the better star average is not the one people write more warmly about.
Uno Calculator ships an update every 5 months, Calculator every 3 months. Both last shipped on October 24, 2026.
