Thanks to @theospears in the Discord for posing this. We came up with the following list of candidates so far:
- Beeminder, for doing what you want
- Anki, for having a superhuman memory
- Khan Academy, for autodidactification
- Mathematica as exobrain probably doesn’t fit in this category (it would open the floodgates if so) but I do use it for various best-self things, like autogenerating intra-day graphs of my weight. There’s also a tiny app I use to keep track of my alliterative alimentation scheme.
What else have y’all got?
