# All in One Calculator vs Calculator Widget

The clearest difference is ads: All in One Calculator at none against Calculator Widget's shown. All in One Calculator also leads on rating (4.7 vs 4.4) and ratings volume (187 vs 16). Calculator Widget's advantage is review sentiment (100% vs 85%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

All in One Calculator holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: All in One Calculator has 187 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 85% of All in One Calculator's written reviews are positive against 100% of Calculator Widget's, so the app with the better star average is not the one people write more warmly about.

All in One Calculator ships an update every 5 weeks, Calculator Widget every 2 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
