Health connect questions - is there an app that consolidates the data? and more!

I'm new to android, I recently got a Samsung Galaxy S24 Ultra (as a lifelong iPhone user I love this phone) and I only just discovered health connect. I was researching it and had a couple questions but I couldn't seem to find the answers on google. The most important one being is there an app that takes all the data that health connect gathers and consolidates it on one app? Preferably an app that I can input my own data into and it sends it back to health connect? Like if I have a ringconn, a Garmin watch and I track my cycle all through separate apps, is there an app that will take the data from those three apps and combine it to give me one final result? Another question - is there a way to see every app that can be connected through health connect? Every list I find only has a few answers, even when I look up a specific type of app. I don't want to have to search every app individually. Last one is broad - is there anything about health connect that I should know or should be utilized? Really any information outside the obvious about the system would be great! I only just set it up and i'm still learning what it does and how to use it. Thank you!
