Verdict

The call

The clearest difference is ads: Qnum › Calculator at none against Calculator⁻'s shown. Qnum › Calculator also leads on rating (4.7 vs 4.4) and monetization model (free vs ad-supported). Calculator⁻'s advantage is ratings volume (3.6K vs 10) and review sentiment (52% vs 40%). On price, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Qnum › Calculator holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Calculator⁻ has 3.6K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 52% of Calculator⁻'s written reviews are positive against 40% of Qnum › Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculator⁻ ships an update every 2 months, Qnum › Calculator every 3 months. The most recent releases landed on October 24, 2026 and October 9, 2026 respectively.
