I use it. Its great for bringing together data from various self-tracking sources and try to get some learning from them.

Why - several reasons. It means I go to one place to look at this data, and its presented in a consistent way. It also helps try to drive meaning from all this data by looking for correlations and commonalities.

Did it bring improvements. For me its helped me get in shape, its helped me find things that have a knock-on effect to my mood and/or productivity.

Interesting..if you mean physical shape, then I always thought that the most effective way to "get in shape" is a simple discipline combined with the primitive reward-system..Literally - just don't eat junk food, work out for 30 minutes per day and if you are happy about results, go ahead and reward yourself by a piece of apple cake or whatever(reduce your normal intake to keep everything balanced - for advanced users). This is so simple and so effective that you don't need anything else - no trackers, no complex data analysis or shrink visits. Amazingly a lot of people ignore this simple path and try various tools like this "exist" thingie.

Information systems have transformed the industrial world. We track metrics for everything, and make decisions from charts of these metrics. People seem to think that because data is so important to S&P 500, it must be equally important to their own person. It's currently just a toy though, that people get tired of after a while. Why would you need to know how many steps you did in a day? It's a gimmick. This will however change once it is agregated by big data, shipped off to ML algorithms that churn the data and tell you what to do via voice interfaces. "You should exercise for 5 more minutes" via Alexa/Siri/Home in your earbuds while exercising.

To me it sounds terrible. It's no secret that work-out length and level of intensity hugely, hugely depends on your mental state at the moment. For instance I recall good old days when I tried impress good looking ladies in my gym and easily pulled/pushed heavy weights that I wouldn't do normally(how silly it was!). Another example is if I face some minor issue that I am worry about(annoying neighbours, upcoming promotion, et) I can't work-our efficiently enough, even being in the perfect physical shape. No fucking Alexa/Siri/Home can detect that. And if one day it is able to do that then it means that the AI just took over the world. Thanks, but I will continue my silly-no AI-most effective approach to the healthy life!

Obviously having discipline, exercising and not eating junk food is a big part of it, and for many people that would be enough. What Exist helped me with on this was keeping me motivated over a period of time and helping me identify other things that were / are impacting my progress (e.g. sleep, work etc). Clearly its not for everyone - but it is certainly something that I value, and something that has helped me.

Oh, I forgot about sleeping. Indeed it's the paramount and it's the most difficult part. Sleep at least 7hrs per day, use the ear plugs and the sleeping mask, don't take sleeping pills and stay away from taking melatonin in capsules. Stop drinking liquids at least 2 hrs before going to bed. Use the anatomic mattress and pillow.

Even water? What if you're thirsty? Any sources?

To me it's just stop eating AND drinking at least 2 hrs before going to bed. My most reliable source is "burn the fat feed the muscle" book that helped me to endorse the healthy way of living this life...Here is the quote:

"I strongly recommend moving the last intake for the day as far away from bedtime as you can. 3-4 hours is ideal, but at least 2-3. This increases the length of the "fast" which in reality nighttime is - broken by breakfast. Using this method consistently is one of the most effective ways to lower body fat - and it doesn’t take a lot of effort"
