Peaks is off to a great start!

I’ve been using Peaks for more than a month now and while it’s not perfect at predicting how I feel it does offer helpful insights that have helped me use my time and energy more productively.

It’s probably worth noting my life is pretty chaotic right now so predicting how I feel at any given moment going to be nearly impossible. That doesn’t mean that the trends aren’t useful; it still lets me get a better feel for when I may be able to get the most out of myself and when it’s totally valid to take a break and rest a bit.

I think Peaks has huge potential as the continue to develop it and improve accuracy and I can’t wait to see what they do with it going forward!

Good start

I like the functionality, assessment and recommendations, but I’m not sure if this app actually tracks sleep or just reads sleep data from Apple health. I can’t tell whether this app will track my sleep if I turn off sleep tracking on from any other app that is tracking sleep. With that in mind, I don’t have a perspective on how well it tracks sleep compared to other sleep tracking apps.

I’ve used the premium versions of the top rated four or five sleep tracking apps extensively over the past 10+ years, and in my experience, the quality of auto sleep tracking differs greatly between apps. The absence of smart alarm functionality for overnight sleep and power naps based on circadian rhythm is the most obvious shortcoming compared to competing apps. All of that said, I like the UI and the info it provides so far… though I’ve only used the app for a couple of weeks.

Pretty much dead on

When I started using this app, one of the first things I noticed was the notifications on my watch seemed to pop up and tell me to do something I was about to do (study, make a decision). One time I was actually saying the words "I need a nap" when I was interrupted by the notification to take a nap.

If all this app did was echo how I was feeling, there wouldn't be a need for it. It's usefulness comes in helping to plan parts of my day and in the insights it brings when I'm not so self-aware. The advice about when to stop things like caffeine are also helpful.
