Kekula: The perfect ad-free math practice app and clock & times learning app for elementary school students. We make math exciting!

With Kekula, learning is child's play: ad-free, fully unlocked and without subscription costs or in-app purchases. Perfect for elementary school students to practice math and learn the times in a playful way!

The exercise app with a unique reward system - vouchers & selected child-friendly videos. Practice math and learn the clock for elementary school - from first, second, third to fourth grade.

From now on, every child will be motivated to practice math tasks while having a lot of fun. Your child will be rewarded for practicing. For every question answered correctly, your child will receive a Kekula thaler.

Once enough coins have been collected, you have the opportunity to watch a short video selected by us. The video is automatically loaded in the app, all player functions are switched off. Once the video is over, it can only be closed; no further short videos can be viewed. The child must first collect thalers again.

Every child is different, every child learns at their own pace and with their own level of difficulty. In the Kekula app, different settings can be saved individually for each child:

- Difficulty level of the Plus and Minus math exercises: Calculate to 10 (ZR10), Calculate to 100 (ZR100), Calculate to 1000 or Calculate to 10000;
- Selection of multiplication and division exercises: The small 1×1 (multiplication table) or the large 1×1;
- Selection of input options: with 4 choices or with open input;
- Set individual rewards in the voucher reward system
- Determine the number of thalers required for a video or voucher;
- Set the maximum length of a video in minutes;
- Setting the maximum number of minutes that can be watched per day;

We know many children's apps that are either overloaded with design, graphics, colors or functions. The children cannot find their way around or get caught up in the menu options or functions. Third and fourth graders often find the design “childish.” We consciously avoid bright colors, funny music or amusing characters. The opportunity to watch a video is the motivator here and ensures the desired learning success.

Online videos players are not without it! But: We offer a child-friendly version in which we select, control and integrate the videos ourselves.
The video is programmed to play so that all other player functions are turned off. It is not possible to watch subsequent videos, forward them or enter and read comments.
Kekula is an app that is easy to understand and intuitive to use. Clear design, clear and easy-to-understand menu navigation.

With the “Send voucher” reward system, a voucher is sent to the email address entered. The voucher is created with the name, the number of thalers and the selected reward and the email is attached.

Not only do math performance at school improve through regular practice, the way to handle money is also trained in a playful way: first “earn”, then save and then spend.
