Description by Matthew Wong Written by the developer, not by AppBrain. Click to read.
FREE TO START
Keep an unlimited watch collection with photos and details. Use the Timegrapher for acoustic rate and beat-error estimates, save up to 10 manual readings, and complete one guided Regulation Coach run. iCloud sync and JSON backup remain free.
UNDERSTAND THE READINGS
Acoustic results depend on the watch, microphone placement and background noise. Manual readings compare displayed watch time with a network reference or the labeled device-clock fallback; timing and reference errors affect the result. Estimates do not replace professional testing.
COMPARE SESSIONS (Chronograde Pro)
Compare two manual sessions by observed daily rate, reading count, elapsed coverage and recorded positions. Preview and share a comparison PDF. A difference does not prove a service effect.
WEAR & SERVICE (Chronograde Pro)
See distinct logged days per watch over 30, 90 or 365 days. Days without entries mean not logged. Keep wear and service records with provider, cost and notes.
PRIVATE REPORTS (Chronograde Pro)
Choose watches, history and a date range, then preview and share a PDF. Serial numbers, notes, amounts and photos are excluded by default. A report is not a backup, appraisal or certification.
MORE HISTORY (Chronograde Pro)
Record unlimited manual readings and sessions, explore rates by position and repeat guided Regulation Coach runs.
REFERENCE & EXPORT (Chronograde Pro)
Use a large reference clock with available network time correction. Import watches from CSV and export records to CSV or Excel.
