Logbook Time Calc

Calculate flight time from paper logbooks.

Logbook Time Calc helps pilots total flight time straight from a paper logbook: scan a page and read the handwritten hours and minutes on your device with Local AI, switch to Cloud AI for the hardest handwriting, or enter your times by voice or keypad.

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.

Cloud AI option

For the toughest handwriting, switch to Cloud AI to read a page with high accuracy. Local AI stays fully on-device whenever you prefer.

Voice and keypad entry

Dictate your times out loud, or type whole times in one field; totals update in real time.

Private iCloud backup

Keep full-quality copies of your logbook pages in your own private iCloud and export them as a PDF.
