Fitdays Comprehensive body composition tracking for your routine

Fitdays is a free health and fitness tool from ICOMON that translates scale data into meaningful insights. Backed by decades of weighing expertise and refined over the past five years using large health datasets, it has been validated by millions of users worldwide, giving it a strong footing in everyday wellness tracking.

The app centers on body composition analysis, presenting 13 core metrics to help you understand changes beyond simple weight. A dedicated girth chart makes it easier to document bodybuilding or shaping goals, while clear step-by-step measurement guidance reduces guesswork. Trend charts visualize progress over time, so you can spot patterns and adjust your routine with confidence.

Multi-user households are well covered, with support for up to 24 profiles on a single account, and there are 15 color themes to tailor the look to your taste. Integration with Google Fit is built in, and the app can synchronize your body measurements with other fitness services, consolidating your data in one place.

A noteworthy strength is the use of scientific models calibrated to reflect regional and ethnic differences, aiming to provide metrics that better align with diverse populations. Combined with a straightforward interface, the experience feels approachable whether you are just starting or fine-tuning a long-term plan.

Fitdays does not try to be an all-in-one training planner. Instead, it focuses on delivering detailed body metrics, consistent logging, and readable charts. If your priority is tracking composition changes and keeping an organized history of measurements, it fits the brief well.

Verdict: a polished, data-forward companion for anyone who wants to monitor body composition over time, share a single account with family or teammates, and keep results synced across popular fitness platforms.
