Contact us →How we work
Approach
A few principles guide every app we make.
01
Learning by doing
Practice is broken into clear steps, with immediate feedback that explains each answer.
02
Built for real use
Our tools are shaped by the classroom and the communities that use them, not by trends.
03
Respect for privacy
We collect only what an app needs. Our logic apps need no account and keep progress on your own device.
The studio
About
Octopup Studio was founded by a philosophy instructor who builds the practice tools used in their own logic courses. What began as classroom software has grown into a small studio with a broader aim: useful, carefully made apps for learning and community.
The name comes from our emblem, a puppy with octopus arms: approachable, curious, and able to handle many things at once. Look closely and it is also a piece of logic. Its arms branch like a decision tree, its face is the “because” sign ∵, and the first three branching points form the “therefore” sign ∴.
