There is an analogous productivity method called "Don't Break the Chain" involving a prominently-placed real calendar, and big red crosses denoting daily successes. It triggers the same (rightly) proud sensation. Anecdotally I preferred it to GitHub streaks (as I rarely look at my profile).

Any habit tracker site/app will also do this for you - I automate mine with GitHub API data, and get a similar effect (the app notifies of streaks daily).

Do you have an example app that will do this for you?

I use coach.me - the automation is via their undocumented mobile APIs https://github.com/jmaddi/liftapp-client (Lift is coach.me's previous branding)

I like https://chains.cc/, though I'm not aware of any way to automate it.

Commit on iOS is a well made example.

OrgMode also handles this out of the box (or at least what you'd call out of the box on OrgMode...)
