Hairspring is a serious iPhone timegrapher for mechanical watches. It measures rate, beat error, and amplitude — and tells you when the signal cannot support a trustworthy answer. MEASURE TWICE, SEE IF THEY AGREE A single number is not proof. Measure the same watch again and Hairspring compares the two runs, includes the statistical uncertainty of each rate, and states whether the readings agree. Save the verification in History and its PDF report. WHAT IT REPORTS • Rate in seconds per day…

What's new

Version 1.0.2 · 27 Aug 2026 · 1 month ago

Measure twice—and keep the evidence. A completed rate verification now stays with the saved measurement in History and in its PDF report, including both readings, their fit uncertainty, the agreement limit, verdict, and analysis version. Amplitude ranges are now consistent throughout the app, position summaries describe observations without over-diagnosing the movement, and Settings reports the installed app version accurately.
