Using our mobile app in conjunction with one of our body composition analyzers or blood pressure monitors, users can directly measure muscle, fat, water, and blood pressure to see how these values, when combined with activity levels and nutritional habits, create a snapshot of whole body health. By regularly reviewing this information, individuals will be able to track progress over time and use this progress as momentum for continued, healthy improvement. Use the InBody App to: ● Evaluate key summaries of recent InBody Tests, active minutes, and nutritional information from the new overview dashboard ● View historic data for body composition in up to one month increments ● Review accurate body composition testing results, graphs, and interpretations ● Monitor blood pressure levels by comparing test results over time ● Manage caloric outputs and monitor daily movement, such as step counts and active minutes, through our training log.
