Anki is a program which makes remembering things easy. Because it's a lot more efficient than traditional study methods, you can either greatly decrease your time spent studying, or greatly increase the amount you learn.

For snap development, it's maintained by my github: https://github.com/woodrow-shen/anki-snap/tree/core20-master
Updates in 2020: The snap will restart to maintain its upstream version based on core20 as the build environment is under Ubuntu 20.04 to fit upstream dependency requirements.
Updates in 2021: As the upstream was sometimes changing the whole build system to use Bazel I was not familiar with, it could be quite hard to migrate this approach to snapcraft.yaml, so in that case I will stop maintaining the anki snap for long term. The version 2.1.35 will be the last stable version for snap, and 2.1.36 for beta/edge is not full upstream release, so maybe you don't use it.
