My name is Michal and I'm from Lemgo, Germany.
I develop native mobile Apps since 2009
and I love to design awesome and useful mobile UI and UX.
In the past I organized and presented some guest lectures and workshops in my main topic mobile usability at Beuth Hochschule in Berlin.Oh and I wrote a book with my colleague Thorsten Stark about mobile usability. Look for the decent hint on the left...
Everything you need to know about mobile App usability is written on 160 pages full of all relevant informations, checklists and secrets about designing a really great UI and UX for iOS, Android, Windows Phone and cross platform Apps.
