Why Rucksack exists
Every meaningful conversation leaves something behind worth keeping. Most of it is gone within days — not because people don’t care, but because nothing lightweight exists to catch it.

Who builds it
Rucksack is built by Marius Nickig in Hamburg. He is also its first user: the app is built to be used by its author, in his own day-to-day, before anyone else is invited to try it.
The rules it is built by
Real use before features
What gets built next is decided by what goes wrong in real use, not by a feature list. Every problem reported from inside the app is triaged and written down.
Nothing made up
No invented users, numbers or testimonials — not on this site and not in the product. When there is nothing to show yet, the site says so.
Say only what it does
Every claim on this site is checked against what the product actually does. What is planned is called planned.
Never guess about people
When Rucksack isn’t sure who you meant, it asks. A wrong fact about a person is worse than a missing one.
