About this app

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

The Kekula app is ad-free, all functions are activated - no annoying in-app purchases.

The exercise app with a unique reward system - voucher & 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 maths with lots of fun. Your child will be rewarded for practicing. For each correctly answered task, your offspring will receive a kekula thaler.

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

Individual settings

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

- Degree of difficulty of the plus and minus math exercises: arithmetic up to 10 (ZR10), arithmetic up to 100 (ZR100), arithmetic up to 1000 or arithmetic up to 10000;
- Choosing the multiplication and dividing exercises: The small 1 × 1 (multiplication table) or the large 1 × 1;
- Selection of input options: with 4 options or with open input;

User friendly

We know many children's apps that are overloaded either in terms of 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 possibility to watch a video is the motivator for the desired learning success.

Online video players are not without it! But: We offer a child-friendly variant in which we select, control and integrate the videos ourselves.
The playback of the video is programmed in such a way that all other player functions are switched off. Watching, forwarding or entering and reading comments is not possible.
Kekula is an app that is easy to understand and intuitive to use. Clear design, clear and easy to understand menu navigation.

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

The learning effects

Not only do the maths at school improve through regular practice, the handling of money is also trained in a playful way: first “earn”, then save and then spend. If the account is empty, you cannot buy anything. The purchases consist of redeeming the Kekula thalers for watching a video.
