Improvement

This app is slowly improving over the last year. I’ve been using. It would like prompts like once a day it asking you how stressed you are how well you slept things like that that could give ongoing trends without being intrusive love that it integrate with wearables looking forward to seeing how it pulls all this data together.

Not Working...Revised

This app was great until it quit working. I open it up and it quickly just turns into a black screen that I can't do anything with.

Edit: Adjusting my rating. Customer service has been on top of it. Hopeful it will start working now.

Keeps going black

Not working at all

Love data. But glitchy app

I love the access to data. The link
S to ways you can improve is super welcome, putting your health into your own hands. However, the app often does not load and shows a black screen.

Thorough and Specific

It reminds me what I am doing well, encourages my lifestyle changes, and suggests more specific tweaks for optimal health. It also appreciates my research deep dives!
