Tickscope — Watch Accuracy

Hear what your watch is really doing.
Tickscope turns your iPhone or iPad into a timegrapher: set the watch by the microphone and read its rate, beat error and amplitude. No extra hardware.

MEASURE
• Rate (s/d), beat error (ms) and amplitude (°)
• Beat rate detected automatically: 18,000, 19,800, 21,600, 25,200, 28,800 and 36,000 bph
• Every result in plain words, like "gains about a minute every 28 days", graded by how confident the reading is
• Coaching tells you what to change when the room is noisy or the ticks are faint

LOOK CLOSER
• Anatomy of a tick: unlock, impulse and drop, averaged from your own watch's beat
• Magnetism check with your device's compass

YOUR COLLECTION
• Photos, measurement history, heritage notes and a wear calendar for every watch
• A chronograph clock face with Breguet hands, moon phase and split seconds
