Learning apps and games by Leon Pließnig
Learning apps without ads. And games I love to play myself.
Children should not be bombarded with ads while they learn, and learning through play is the best way to learn. Recheneule (maths, grades 1 to 4) and Temporis (history) are on Google Play. Next to them I build games that interest me: Rookspire (chess) and Echo (idle) are on the way.

How I build apps
Learning without ads
In Recheneule and Temporis children see the task and nothing else. Recheneule adds a free parents section that shows what a child has mastered.
Games with respect
Rookspire has no ads. Echo only has reward videos that you start yourself, no banners and no pop-ups.
No account, works offline
Progress stays on the device. All apps work on the train, on holiday and without a connection.
Two learning apps, two games.
Recheneule and Temporis are on Google Play, Rookspire and Echo follow. Every app has its own topic and its own look. What they share is the approach: honest and free of tricks.

Built by one person, in Austria
I am Leon Pließnig. I design and build learning apps and games myself and read every support message. That is why they stay small, clear and honest.
