Every screw has a way back.

Caliber Trail keeps teardown steps, bench photos, numbered markers, tray cells, parts, and notes connected—then presents the same record in reverse for reassembly.

Record.
Trace.
Return.

Document each removal step with one optional photo, numbered markers, movement module, tray location, and bench notes. Track parts and manual timing readings, then export a PDF or portable backup when the record needs to travel. Caliber Trail supports iPhone and iPad running iOS or iPadOS 17 or later.
