Tracking the results of your fitness efforts

Measure Your Body

Track daily changes in body composition such as weight, percent fat and lean mass.

Model Performance

Understand how training load effects your fitness and fatigue levels throughout the season.

Prepare With Confidence

Plan your build and taper to pinpoint expected performance on race day.

Fitness results quantified

Tracking your workout effort is only half the story. Complete the picture by recording the resulting changes in your body composition.

Manually enter your daily weight or body fat from your mobile phone, or turn on auto-sync to a compatible digital scale.

Training Load that doesn't melt your mind

You shouldn't need a PhD in statistics to train with data. Our training load model gives you sophisticated analysis in an easy-to-use package.

We take effort data from all your workouts - from indoor, to outdoor, road to pool to gym - and show the impact on your performance in simple, intelligible charts.

Take it to the future. Predict your performance on race day by planning workouts with estimated effort. Stay on target and eliminate the guesswork out of tapering and recovery days.

Dig deeper into the numbers

Our interactive health charts let you see the details behind the data.

Hover over a chart with your mouse pointer to quickly inspect history at a particular date. Or click and drag across a region to see starting, ending, and change metrics.

Take control — it's your data

Just like your workout data we also provide full editing features for your health data.

Editing of manually logged or data automatically synched from a device or app is quick and easy.
