WhatDaFit
The fitness app for everyone with a body!
WhatDaFit was created by a Vienna-based startup. Unlike the existing fitness apps on the market, which all take themselves very seriously, WhatDaFit brings fun and humor into training. 150 diverse workout plans are accompanied with a wink by well-known personalities such as Marco Pogo, Austrofred, “Evil” Jared Hasselhof, and others.
The app offers a free basic version with a limited selection of workout plans and the standard voice. For €3.99 per month, users can unlock all 150 workout plans, and for a one-time payment of €8.99, a celebrity voice can be permanently unlocked.

Implementation
AppJoy was responsible for the entire technical implementation — from infrastructure to the mobile app. Before investing significant time and money into filming workout plans and recording voice tracks, the WhatDaFit concept had to be technically validated. For this purpose, a feasibility study was conducted, creating a prototype that contained only a single workout plan consisting of three exercises. The goal was to test whether the individual video and audio tracks could be merged on the user’s device into a complete workout plan without causing any synchronization issues.
After the prototype met all expectations, there was a longer development pause during which all video and audio recordings were filmed and edited, and the resulting files were uploaded to the server. In addition, medani GmbH designed a distinctive and recognizable design for the app.
Next, an MVP was developed: the workout plans were completed, the first celebrity voices were available, and workouts could be performed. The app was ready for in-app purchases, allowing users to buy the premium subscription and the first premium voices.
The MVP was then expanded with additional premium voices, and new features were introduced, such as a global and country-specific leaderboard for users.
