Frequently Asked Questions

Evident is a scientific self-tracking app that uses the Pearson correlation coefficient to uncover hidden connections between your daily habits and your wellbeing. It's like having your own personal science lab in your pocket.

You track your daily habits and wellbeing metrics. Evident then analyzes your data using statistical methods to find correlations between what you do and how you feel. After collecting at least 7 data points, you'll start seeing meaningful insights.

Evident organizes your health into 4 pillars: Sleep (duration, quality, consistency), Wellbeing (mood, stress, social connection, mindfulness), Fitness (activity, exercise, consistency), and Productivity (deep work, task completion, focus).

The Evident Score is a comprehensive score from 0-100 that combines data from all 4 health pillars to give you an overall picture of your wellbeing. It helps you track your progress over time.

Personal Studies let you create and test your own hypotheses. For example, you can study whether coffee affects your productivity or if meditation improves your sleep quality. Evident will analyze your data and show you the statistical correlation.

You can create unlimited custom trackables in 5 formats: Numeric (e.g., cups of coffee), Boolean (yes/no), Scale (1-10 rating), Choice (multiple options), and Time (duration tracking).

Statistical validity requires a minimum sample size. With fewer than 7 data points, correlations could be misleading or random. This 7-point minimum ensures that the insights you receive are statistically meaningful and not just coincidence.
