Thank you! No other program or app can really do for me what Tiddlywiki does for free! I would have had to use multiple android apps to have something like this.
The ācommentsā style UI (with boxing gloves and other emoji in circles), whatās this used for? Journaling?
Yes, Iām trying to take note of my progresses for different things, in the freeform way of journaling (I found that a yes/no functionality is not applicable to every habit I try to track, and I wanted to see these different journal topics in a stream-like timeline)
How did you build the calendar?
I used EricShulmanās TiddlyTools/Time/ParseDate.js as the base for all date-related stuff. I built the calendar datepicker and days/months scroller upon this, using TW widgets and some specific grid-positioning (based on the dateās weekday) by CSS.
What engine does the graphing / plotting of weight?
It is <$wikify>-ed CSS 
, hereās a sample of how I did it:
<$wikify name="clip-path" text="""
<$list filter="[list<db>nsort[]]" variable="x">
<$list filter="[<db>getindex<x>]" variable="y">
<$let
top={{{ [<y>subtract<min>] }}}
bottom={{{ [<max>subtract<min>] }}}
>
{{{ [list<db>nsort[]allbefore<x>count[]divide<count>multiply[100]] % +[join[]] }}} {{{ [<top>divide<bottom>subtract[1]] +[abs[]multiply[100]] % +[join[]] }}},
</$let></$list> </$list> 100% 100%, 0 100%
""">
<div class="lg-datum lg-datum-color" style={{{ clip-path: polygon( [<clip-path>] ); +[join[ ]] }}}> </div>
<div class="lg-datum lg-datum-mask" style={{{ clip-path: polygon( [<clip-path>] ); +[join[ ]] }}}> </div>
...
this produces a variable=clip-path that I use later on in the .lg-datum div
Is this a custom layout? A special ālife trackingā tiddler? Something else?
Itās just a tiddler with all its contents a relationship between system tiddlers. A button within it allows me to set this specific tiddler to āfull-screenā so it acts like an app, and my startup is set to this tiddler specifically
What is your sync story with this? Do you ever edit on another device?
The rare instances I needed to edit on a pc I e-mail myself the single wiki file
Trully Iām waiting for this kind of workflow: a single TW locally stored on my phone (syncing to a google drive folder), editable in Tiddloid, that when saved, will also save to a Tiddlyhost siteā¦ so I can edit it in any PC browser that will also update the google drive synced wikiā¦ and so onā¦ basically I wish thereās an integration between Tiddloid, google drive and tiddlyhost.
Pipe dream, I know 
EricShulmanās stuff really helped me with these! I love tinkering with his stuff but I do understand why they are not part of the core.
