Just need to be able to rearrange/reorder the starred items. ### 5/5 — This one’s for the data geek girlies *2024-05-26* Love this app, such a clever way to display loads of fitness and health data in an intuitive way that’s actually based in science (all while citing sources for calculations where appropriate!) A must have for data nerds ### 5/5 — Nice graphs *2023-12-13* Stumbled upon this app in the app store and really glad I did. Great visualizations of your health data. Would be nice to have some of those visualizations available as Apple Watch complications. ### 5/5 — Refreshing new way of looking at health data. *2023-08-28* My favorite part is the landing page where you can pick parameters that are important to you and being able to quickly tell when something is out of balance in a form of constellation. Apple Watch is an amazing tool but native health app doesn’t do a good job providing analysis of data collected. ### 5/5 — Good for bike training *2023-08-08* This app makes it easier to see stats you want to track than the Health app. I’m using it to map my VO2max and cycling workouts. You can make a dashboard with the graphs you want to see in one place. UI is super minimal with no ads. ## Frequently asked questions about Constellation Health & Fitness ### What kind of data can Constellation Health & Fitness analyze?

Month-over-month and week-over-week comparisons are also available in the details sheet for all cumulative metrics. The nutrition page has improved warnings for metrics with DRI information. Now only the metrics where your estimated probability of adequacy is low will be highlighted in orange. You can now add metrics to your constellation from any details sheet using the star icon in the top bar. You can now adjust Constellation’s black/white value to soften the contrast throughout the app. Many more interface improvements and bug fixes. ### 1.1 — 2023-05-23 New sleep metrics: sleep efficiency, sleep onset latency, wake time after sleep onset, and more.
