Very nice! I'd recommend that the landing page either shows an example right away (the Carl Sagan one is great) or make it more obvious to take a look at one first - took me a minute to figure out what this was for, but the example made it click immediately.

It'd be nice to have some default layers based on https://waitbutwhy.com/2015/12/the-tail-end.html

Its funny to me that adolescence is until 20, where I'm from its 18 or even sooner.

"Are you still alive?" dropdown is diabolical :-)

I like the use of the Weber-Fechner law, that's a lens I use to think of age as well :) The idea is that experienced time is proportional to log time, i.e. it's why time seems to move faster as we age. You could even measure your age in powers of two, like we do octaves.

Bug report - on iPad it's impossible to exit full screen mode, need to reload the page.

The share & restore feature is not working for me. Only the birthday is restored. Other settings & skip tutorial are reset.

Hi, I made this! I don't know how it got to this page. Thanks for the support :)

I started the day singing, then I opened this link. ;_;

Bug report: Your calendar labels me as “mature adult” when in fact I am not.

So what is it for? To know how life periods span and change one into another? I like it but I am struggling to find a use case

Design is amazing. Well done. I inserted my birthday and got "Enter a real Gregorian date.". Only then I understood I needed to insert "mm dd yyyy". User error for sure :) but this date format really annoys me

Very cool! Thanks for including psychophysics setting. I wish there was one for date format because mm/dd/yyyy breaks my brain a little.

Love it!

Bug report, if you're the author: I can't delete periods.

Feature request: I wanna be able to move periods from one layer to another.

I like how far mature adulthood goes :) One never gets old.

Yeah no I don't want to use lifetime trackers on myself. It is a trigger for depression

As a 54 year old, viewing the grid with the Weber-Fechner "psychophysics" grid is depressing as hell. Thanks.

the design is so beautiful

I saw "import from LinkedIn" and closed the tab.

Where do I put my mother’s maiden name and my first pet name?
