Interval Timer


We are two developers striving to provide the best tools for the fitness community.

As enthusiastic athletes, we were disappointed by the poor market for HIIT and interval training apps. So, we decided to develop our own.
For us, Lapz embodies what every fitness app should be: Functional, intuitive and quick to use.


Max is a professional iOS Developer and hobby athlete. His favorite training style is calisthenics.

In his spare time he is developing Lapz or tinkering with other coding problems.


Fabian is responsible for iOS and Web Development.

He is also a calisthenics enthusiast and tries to maximize his gains with complex training plans.
