Liberty Vitals: Smart Ring

Liberty Vitals is an independent app for people who wear a Bluetooth smart ring. It reads your ring directly, keeps your data on your phone, and transforms raw measurements into meaningful daily summaries, sleep analysis, workout tracking, and long-term trends. Built with purpose. Designed with research. Focused on making your data useful. Significant development and research have gone into making Liberty Vitals as capable, informative, and useful as possible. Rather than simply displaying the numbers reported by your ring, the app combines the ring's capabilities with your phone's processing power and carefully developed algorithms to turn individual measurements into a more complete picture of your daily activity, sleep, recovery, and overall trends. Extensive research has informed both the selection of the most useful health and activity metrics and the way that information is analyzed, organized, and presented. The goal is to help you understand what your data means, recognize patterns over time, and get more value from the device you already wear. Smart rings have inherent limitations. Their size, sensor technology, fit, movement, and recording conditions can all affect measurement accuracy. No smart ring can measure everything perfectly, and no app can eliminate those physical limitations. Liberty Vitals takes this into account, using the available data, phone capabilities, and app algorithms to provide consistent, useful information while recognizing that individual measurements are estimates rather than guaranteed exact values. The result is an app designed to do more than show you numbers. It's designed to help you make sense of them. WORKS WITH R11M-type rings (such as those from UniJethro) and R02-family rings (such as those from Colmi). Unsure about yours? Ring Check shows what your ring supports. Liberty Vitals is independent and not affiliated with or endorsed by any ring maker.
