About project
FitTracker is a mobile fitness platform that tracks workouts, monitors health metrics, and delivers personalized training recommendations based on performance data and user goals.
Challenges & Solutions
Problem
Fitness apps were either too generic to drive meaningful progress or too complex for casual users — resulting in low engagement and poor adherence to training plans.
Solution
Zylo designed an adaptive fitness tracking interface with goal-based training plans, intuitive metric logging, and motivational progress visualization that drives daily use.

System Architecture
A health data aggregation backend connects wearable device APIs, manual logs, and structured workout templates — feeding a recommendation engine that personalizes training load.
Interface Engineering
Workout tracking, progress charts, and training plan management are organized in a flow-based UI that minimizes steps between opening the app and completing a session.
Progress that adjusts to you — every session, every goal.
