Story

Small studio. Sharp focus on craft.

How we build

Clavory is a software studio focused on two things we love: applications that respect people's time, and games that are genuinely fun to come back to. We build for everyday moments — a few minutes at the piano, a quick round of math practice — and we sweat the details that make those moments feel good: instant feedback, visible progress, and zero friction to just open the app and start.

The best apps don't ask for your attention. They earn it, one satisfying moment at a time.

Piano turns your phone or tablet into a full-featured keyboard: play freely, learn songs step by step, race falling notes, or go head-to-head in a duet. No login, no subscription — just open it and play.

Ways to play

  • Free Play — a full, responsive on-screen keyboard for playing anything you like.
  • Practice Mode — step-by-step guided lessons that highlight the next note and wait for you.
  • Falling Notes — classic note-highway gameplay: notes fall toward the keyboard in time.
  • Key Smash — a fast-paced rhythm challenge with combo streaks and live scoring.
  • Duet Mode — two players, one keyboard — play together or go head-to-head.
  • Record & Share — capture a performance and share it as a video.

Math Ninjas turns everyday math practice into a fast-paced, encouraging game for kids — built around real teaching, not just grading. Kids tackle addition, subtraction, multiplication, and division in short, focused rounds, earning stars, unlocking colorful ninja belts, and building daily streaks as their skills grow.

Features

  • 7-question rounds & star ratings — short, focused sessions that build real confidence.
  • Math Coach — a wrong answer gets a friendly step-by-step hint before another try, not just a score.
  • Custom training — choose Easy, Medium, or Hard and pick exactly which operations to practice.
  • 20 levels of progression — math genuinely gets tougher as kids climb.
  • Collect ninja belts — level up through 20 unique belts, from White to Legendary Ninja.
  • Progress reports for parents — a gated dashboard shows accuracy, time spent, and strengths by operation.
