Quento is a delightful little math puzzler without ads that is fun for kids and adults. Over the past 8 years it has been played all over the world by children, parents, students, teachers and basically anyone during commutes, in schools, on camp sites, during lunch breaks, at offices and in bed before going to sleep. Enjoy endless rounds of quick play, a unique daily challenge, different sets of numbers and a zen mode. And with the special "Quento for Schools" mode, students can play in class, in smaller groups or engage individual challenges. Here's what the media said: Cult of Mac: "Quento is a delight. It’s different, it’s challenging, it’s got something to offer for kids learning math in school and for adults who want to give their brains a workout. Fantastic." iMore: "Quento is an excellent math puzzle game for all ages. Both young kids and experienced mathematicians will enjoy it." AndrCentral: "Look, I'm not a math guy. So what am I doing playing a game all morning that involves adding and subtracting? Moreover, why am I still playing it now? For the life of me, I don't know. But there's something about Quento that keeps me coming back." How does it work? Simple! Quento gives you the solution to a sum and you'll have to do the math. To play, just swipe from a number to a + or - and to another number again. Stars are earned when the sum adds up to the challenge above and before you know it you've progressed a round! Quento comes without ads, and the free version truly offers more than enough challenges to make it a perfect match for kids and students to use at schools. There is an optional single in-app purchase that unlocks the toughest challenges and more number sets for those that want to work out even more. This way we hoped to offer more than enough for everyone to enjoy!

Verdict

The call

The clearest difference is review sentiment: Quento at 77% against Binary Sudoku+'s 40%. Quento also leads on ads (none vs shown) and iOS requirement (9.0 vs 15.0). Binary Sudoku+'s advantage is rating (4.7 vs 4.3) and ratings volume (190 vs 9). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Quento sells 1 one-off in-app purchase and Binary Sudoku+ sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Binary Sudoku+ holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Binary Sudoku+ has 190 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 77% of Quento's written reviews are positive against 40% of Binary Sudoku+'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Quento ships an update every 3 weeks, Binary Sudoku+ every 9 days. The most recent releases landed on October 4, 2026 and October 8, 2026 respectively.
