Hearkle is a small collection of daily games, all about sound and pitch. Each game gives everyone the same puzzle each day, so you can compare and share your result — no account, no download, nothing leaves your device. Every tone is generated live in your browser; there are no audio files.
Hearkle turns ear training into a daily habit. Hearing whether one tone is higher or lower than another, and by how much, is a trainable skill rather than a gift reserved for the few — and short, regular practice builds it faster than the occasional long session. Because every game takes only a minute or two and gives everyone the same puzzle, it is easy to come back tomorrow.
It is built privacy-first. There is no account to create and nothing to install; every tone is generated live in your browser, so no audio files are downloaded and nothing you play ever leaves your device. You can compare and share a score without handing over a single personal detail.
It is made for anyone who works with sound. Singers and instrumentalists use it to sharpen intonation, learners build a musical ear from scratch, and teachers run it as a quick daily warm-up for a class. No theory is needed to begin — if you can tell a high sound from a low one, you can start today.
Every daily game and every Learn guide stays free forever. A Personal Pass simply adds optional progress tracking — trends and export — while our tools for teachers and schools let you assign any game with a single link and follow a whole class. Understand how pitch works, then train it.
Use headphones or turn your sound on. Tap to start audio (browsers require a tap before playing). Hearkle is the sister site of Huekle, the daily color games.
