I do think this could be an amazing local-storage service though, not free, still paid as a subscription model.
I've seen how much hard work and emotional energy they've put into their product over at least 4 years. And I've observed them go through a whole lot of different experiments on how to optimise their on-boarding process for new customers.
I can tell you that their current signup process has been tested and optimised to within an inch of its life, in order to get the outcome they want, which is to attract users who are serious about using the product and will be happy to pay for it as soon as they're convinced it does what they need.
As the article says and as another commenter pointed out, they now make enough money to pay both founders a modest monthly wage.
They don't sell advertising in the app, they don't sell your data, and they haven't taken funding. Every cent they make is from people who love their product.
Please believe me when I tell you they really don't mind when people are turned off by the requirement to enter payment details.
To be fair, though, I’m largely in agreement with you in this case. For products like cloud infrastructure, where the company is fronting real costs, the requirement makes sense to prevent abuse. But this product has low marginal cost per user, and also loses all of its value if a user recreates his account.
Unless, of course, you could import historial data somehow. But then maybe just make that feature not available on trial.
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.
Even water? What if you're thirsty? Any sources?
"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"
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!
