The Developer

MangyByte Ltd is the independent development studio of MangyByte Ltd. What started as a passion for building things has grown into a portfolio spanning mobile apps and wearable tech for racket sports.

From running competitive tennis leagues for a single club, to a multi-sport league platform for any club, to tracking scores on your wrist — every project is built with care, attention to detail, and a genuine love for creating software that people enjoy using.

The portfolio is growing. More apps and more platforms are on the way. Stay tuned.
