Here you see my portfolio of my apps & websites, that I did for clients and myself.

My Apps

iOS APP „Sail Learn“

iOS APP „Child Shapes“

iOS APP „Ice Puck“

This was my first App and is only in German. This App is about sailing and sailing theory. It also has three quiz where you can test your knowledge!

This App is for children developed, but also fun for older people! You have to bring diffrent Shapes to the right place. It also has an AR Game, where you play in the Real World.

This was my first gaming App. This App is about a Ice Hockey and you have to bring the puck to the goal, but there are enemy players!

iOS APP „Pig Oboli“

iOS APP „Rabbit Pepper“

iOS APP „Doggy Chuck“

This App is for Money Saver and there you can save your Pocket-Money. This App is also for young children but also adults can have fun with that App.

Rabbit Pepper is my pet and also has now a animated iMessage App.

Doggy Chuck is about the pet of my Sister and also has now a animated iMessage App.

macOS APP „HomeCapital“

coming soon...
