Logbook Time Calc

Scan your paper logbook and get your total flight hours in seconds. The app learns your handwriting and gets smarter with every use.

Calculate your flight hours in seconds — just point, scan, and done. Logbook Time Calc is the essential tool for pilots who want to quickly and accurately calculate their total flight time directly from their paper logbook. Just take a photo of your logbook page and let the app do the math.

HOW IT WORKS Point your iPhone camera at any page of your flight logbook and capture the image. Logbook Time Calc uses advanced on-device OCR (Optical Character Recognition) powered by Apple's Vision framework to automatically detect and read the hours and minutes from each row of your logbook table. The app then instantly calculates the cumulative total flight time, displayed in hours and minutes. But it doesn't stop there. Every time you manually correct a misread value, the app quietly learns from it. Over time, it builds a personal profile of your handwriting — recognizing the way you write your numbers — so that recurring OCR mistakes are corrected automatically, before you even see them. The more you use it, the more accurate it becomes for your specific logbook. Everything runs entirely on your device — no internet connection required, no data ever leaves your iPhone.

KEY FEATURES Instant Logbook Scanning — Photograph your logbook page and get your total flight hours in seconds. Smart OCR Technology — Apple Vision-powered text recognition accurately reads handwritten and printed hours and minutes from your logbook grid, even in imperfect lighting conditions. Learns Your Handwriting — The app adapts to your writing style over time. Each correction you make trains a personal on-device profile that automatically fixes recurring misreads in future scans. AI-Assisted Recognition — On supported devices, an on-device language model uses your correction history as additional context, making the scanning engine progressively smarter with every use. Auto Table Detection — The app automatically identifies the logbook table in your photo, isolating rows and columns for precise extraction. Manual Crop & Correction — If the automatic scan needs a hand, use the manual crop tool to define the exact area. Real-Time Total Calculation — Flight time totals update instantly as you review or edit entries, always showing you the correct cumulative result in hours and minutes. 100% On-Device Processing — All scanning, learning, and calculations happen locally on your iPhone. No account, no cloud, no privacy concerns. Clean, Distraction-Free Interface — Designed for pilots, by a pilot.

PERFECT FOR Student pilots logging training hours, private pilots tracking currency, commercial pilots verifying totals before check rides, flight instructors and any aviator who keeps a traditional paper logbook and wants a faster way to sum up flight time.

YOUR PRIVACY, GUARANTEED Camera access is used solely to capture your logbook page. No images are uploaded or stored externally. Your data stays on your device, always.
