Hey Product Hunt 👋
I’m Pabloku, an Android developer from Spain and the maker of Numday.
I built Numday because I love short daily challenges, but I wanted something more active than scrolling and more social than a classic brain-training app.
Numday gives everyone the same 7-calculation chain each day. You have 90 seconds to solve it, then you can compare your result in the global ranking or in private leagues with friends, family, classmates, or coworkers.
A few details:
• Android-only for now
• The daily challenge can be tried without an account
• Sign-in is only needed for rankings and private leagues
• Each challenge is short enough to become a small daily habit
I’d love your feedback on three things:
1. Does the challenge feel too easy, too hard, or just right?
2. Is the onboarding clear enough?
3. Would private leagues make you come back tomorrow?
Thanks for checking it out. I’ll be around today replying to comments and feedback.

Who hunted Numday?
Numday was hunted by Pablo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
