Logbook Time Calc

Calculate flight time from paper logbooks.

Logbook Time Calc helps pilots scan a logbook column, detect the table, read handwritten hours and minutes, and compare the recreated cells against the original crop.

Detected hours and minutes in Logbook Time Calc

Why pilots use it

Less manual arithmetic, more confident totals.

Automatic analysis

Capture and analyse in one flow. The app crops the table and prepares editable hours and minutes.

Manual correction

Every detected value stays editable, so the final total remains under the pilot's control.

Dark and light workflows

A cockpit-inspired interface keeps the scan, crop, detected table, and total readable.

App details

Built for iPhone logbook checks.

Platform

Workflow
