Escapement is a practical timegrapher app for mechanical watch owners, collectors, and watchmakers.

Free features:

• Acoustic timing measurement for mechanical watches

• Rate, beat error, amplitude, BPH, and confidence readings
• Watch collection with brand, model, and default settings
• Basic app settings and measurement controls

Escapement Plus subscription unlocks:

• Multi-position timing reports
