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!
