Questions & Answers

As answered by people managing Time Sink and Space Repeat.

What makes your product unique?

Space Repeat's answer:

Space Repeat removes everything that distracts from actual learning: no feature overload. It focuses purely on active recall and spaced repetition, the two techniques with the strongest scientific backing for long-term memory.

Why should a person choose your product over its competitors?

Space Repeat's answer:

Most study apps optimize for engagement, not retention. Space Repeat is intentionally minimal. It shows you cards exactly when you're about to forget them, adapts to how hard each card is for you, and tracks your retention over time. The free plan is fully usable with no tricks.

How would you describe the primary audience of your product?

Space Repeat's answer:

Students who want to remember what they study for the long-term, especially those preparing for exams or learning large amounts of material over time.

What's the story behind your product?

Space Repeat's answer:

I'm a student myself. I tried the flashcard apps that already exist, but none of them felt right. Some were too flashy, packed with features I didn't need. Others were too bare-bones, with free plans so limited they were barely usable. I wanted something in the middle: a focused app that does a few things really well, with no distractions and a free plan you can actually use.

  • Information That Wonโ€™t Fit Inside Your Head: Journals with and Without Bullets
    I love that my job is sitting on my ass drawing stuff but there are definitely times when it is still Work that I have to force myself to keep doing. Sometimes I sort of sit there watching art fall out of my stylus. Sometimes I am Sisyphus muttering and cursing as I push this fucking stone up this fucking mountain for the millionth time. "Flow" is overrated IMHO. It's certainly worth building working methods that... - Source: Hacker News / almost 4 years ago
  • Take More Screenshots
    I've been happily using [Time Sink](https://manytricks.com/timesink/) by Many Tricks to do this for about a year now. It does not automatically merge into a timelapse, but this is accomplished easily with ffmpeg. - Source: Hacker News / almost 4 years ago

  • Software Devs of /r/osx, I've moved from Linux to OSX and need to replace my Polybar workflow
    For time tracking I lean on Time Sink. If you want something more manual then I feel like there are a zillion task-tracking timers out there but I couldn't point you to any one in particular. Wikipedia says Toggl has an OSX app so maybe you wanna look at that one first. Source: over 4 years ago
