I’ve been using this app since shortly after the release date. It’s been very helpful to understand where I’m at throughout the day and making sure I’m hitting my limits. The reminder notifications help tremendously if I get caught up in the moment on something else. I really like that you can track your alcohol intake so you can see how to adjust your hydration. Great app overall!
