SitzProbe.app – Spaced Repetition for Performances and Complex Tasks

Hacker News

Hi HN! I’m super excited to share with you my first completely self-developed app: SitzProbe[1]. This is an application that came from a simple (yet unfilled) need I had. When sitting down to practice music, I had trouble keeping track of all the different pieces I knew and which ones I have or haven’t played recently. But I wanted to make sure I kept practicing the old ones mixed in with the new, so ended up with a mess of lists and notes on my phone. I’ve also always been fascinated by the theories of spaced repetition[2], but they’ve always been geared toward very atomic bits of learning (languages, technical vocabulary, etc.). So I decided to combine the two into a slightly fancier todo list: one where your tasks will never be “done”, but if you do them well, you do them less often; and if you don’t do so well, it will prompt you to repeat them more often until you do them better. As far as I could find, this sort of thing wasn’t available, so I made one. Any feedback, comments, critiques, are appreciated. There are certainly bits of the app that aren’t finished (what software is ever complete?) but would also love suggestions on extra things I might consider adding in the future.
