Tickscope — Watch Timegrapher

25 free measurements. Unlock unlimited use for $4.99 — one time, forever. No subscriptions. Your watch is a machine. Now you can measure it like one.

Tickscope turns your iPhone into a professional timegrapher. No cables. No adapters. No $500 equipment. Just place your mechanical watch near the microphone and tap Start.

Within seconds, you'll see exactly what a watchmaker sees: rate, beat error, and amplitude — rendered live on a dual-trace timegrapher plot that builds in real time.

Tickscope's measurement engine is built on the same mathematical principles used by professional service-center timegraphers — tuned over months on dozens of watches of all ages and types, from modern Rolex calibers to 60-year-old vintage movements. The result speaks for itself.

— WHAT YOU'LL LEARN ABOUT YOUR WATCH —

Rate: Is it gaining or losing time? By how much per day?
Beat Error: Is the balance wheel ticking symmetrically?
Amplitude: Is the mainspring delivering enough energy?

These three numbers tell you everything about your movement's health. Tickscope measures all of them from sound alone.

— HOW IT WORKS —

Place your watch below the phone's microphone. Tap Start. That's it.

Tickscope auto-detects your beat rate (18,000 to 36,000 BPH) and begins plotting tick-by-tick deviation in real time. The dual-trace plot separates tick from tock — the same visualization used by Witschi and Timegrapher machines that cost hundreds of dollars.

— BUILT FOR COLLECTORS —

Save every watch you own. Add photos, reference numbers, movement details. Measure in all six standard positions (DU, DD, CU, CD, CL, CR) and see how your watch performs across them on a radar chart.

Track accuracy over weeks and months with trend charts. Spot when a service is due before problems get worse.

— CHALLENGE YOUR WATCH —

Think your watch can pass COSC? Tickscope's chronometer challenge mode tests your movement against the official criteria. Measure five positions, get a score, and find out if your watch makes the cut.
