Bookmarkable URLs

Every URL carries a tempo. Bookmark different tempos and open whichever you need.

t0ck.app/90: 90 BPM
t0ck.app/140/3-4: 140 BPM, 3/4 time
t0ck.app/60/4-4/8: 60 BPM, 4/4, 8th-note subdivisions
t0ck.app/90/3-4/8/wood: Full recall — tempo, time, subs, sound
t0ck.app/90/flat: 90 BPM with no downbeat accent

Time sigs use a dash in the URL (3-4, not 3/4). Everything after the tempo is optional. # works too if your browser strips paths.
