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. 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!

Ratings and Reviews

Yay for iOS 11 Support


I’m so glad to see this game updated for iOS 11. This is one of my favorite distraction games for at the bar or in the elevator etc. I love playing it with a friend on a night out in those clubs where it’s too loud to talk to each other; Just hold the phone between each other and see who can solve it faster!

Really just a great idle game that you can put down and come back to at any time because it’s not time based, much like solitaire. It’s great for when you need to keep your hands busy or want a simple distraction at the table. People often ask me what it is and it only takes a second to teach them how to play. Can be a good ice breaker that way too.

Small bug, otherwise great game


Hi! I've had this app for a long time (going on 6+ years), so I was excited to see the update!

Anyway, I just got to Round 1000 and the text at the top doesn't fit in one line, so it wraps and takes two lines. However, this shifts the entire UI below it down, so the buttons on the bottom (hint, settings, number pool, anddaily puzzle) are only halfway onscreen.

Nothing major, just a small bug in the UI. Keep up the good work!

If you want to work your mind, this game is for you!

Family Williams

The game starts out easy with one given number, you must find this number with the amount of numbers given and the order in which they are presented. The game changes once you complete the given numbers. The numbers in which you use to make the specified number (by adding or subtracting your given numbers and there placement) increases one by one for instance you must make the number 14 by adding and subtracting the numbers presented.
Overall the game is really fun and a great game to play when waiting around! But also I must make you all aware! This game is addicting! The game is amazing!
