Tickline: Watch Timegrapher

Tickline turns your phone into an acoustic timegrapher for mechanical watches and pendulum clocks. Lay the watch on the phone, crown by the microphone, and it times every beat: rate, amplitude and beat error, with a live paper tape like a bench timing machine. Every feature is free, with no measurement limit, no account and no subscription. A REAL TIMING MACHINE READOUT • Rate in seconds per day, amplitude in degrees, beat error in milliseconds. • The beat rate is detected automatically, from 12,000 to 43,200 bph, or set by hand. • Live paper tape: a fast watch leans one way, a slow one the other; two lines mean beat error. • The sound of each beat, with its first and last sounds marked, so you see what is measured. • No number until the readings are steady. A noisy moment keeps the last good reading, marked as held, instead of showing nonsense. • Says so when it hears a quartz watch, instead of measuring the wrong thing. POSITIONS TEST • A guided test dial up, dial down and standing on its edge (2, 5 or 6 positions). • Each position is recorded by itself once three readings agree. • Mean rate, delta between positions, mean amplitude and the drop from flat to upright: the figures a watchmaker regulates by. ACCURACY ON THE WRIST • Compare the watch with the phone's network time every day or two. • Tickline works out the real daily rate as you wear it, with a chart of the offset. PENDULUM CLOCKS • In-beat figure and a beat bar: see at once whether tick and tock are evenly spaced. • The clock's measured beats per hour, and its rate in seconds per day once you give the nominal rate. • Clock train calculator (beats per hour from the wheel and pinion counts) and pendulum length. YOUR COLLECTION • Every watch and clock with its beat rate, lift angle, photos, notes and every reading. • Service log (serviced, regulated, demagnetised) and a reminder when the next service is due. • Share a timing report as a PDF, export readings as CSV. • Backup and restore to one file: nothing is lost when you change phones. HONEST AND HELPFUL • Lift angle presets by movement family, with the common 52° as default. • A guide to what the numbers mean, healthy ranges, the positions, putting a clock in beat, and when a watch needs a watchmaker. • A phone microphone is not a bench machine with a contact pickup: Tickline shows a confidence-checked reading and tells you how to place the watch for the best result. English, German, French, Italian, Spanish, Portuguese and Japanese. Works offline. Sound is analysed on the phone, never recorded or sent. Free with ads, never while measuring; one optional purchase removes them, and every feature stays free either way.
