Questions & Answers

As answered by people managing Space Repeat and CodeCrafters.

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.
