What this is
Twelve Notes is a set of small music tools that open in your browser and do one job each. Tune an instrument, set a click, find a song's tempo, name a chord from its notes, or train your ear to recognise intervals, chords and modes. Each page explains itself in plain words first and gives the proper name second.

Questions
Is it free?
Yes. There is no account and nothing to install.
Does it work on a phone?
It is built for current mobile browsers. Phone microphones are weak on very low notes, so hold the phone close when you tune a bass.
What does the microphone do?
The tuner and Hit the note listen to find your pitch. The sound is analysed in your browser. Hit the note can also record your voice into a replay clip on your device, if you leave that box ticked.
