Logbook Time Calc

Read full description

Calculate your flight hours in seconds — point, scan, done. Say them out loud. And now, see your night time on a 3D globe. 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. Photograph a page and let the app do the math, flip to the manual table and enter your times by voice or keypad — or swipe to the night page and let the globe split your flight into day and night. HOW IT WORKS Point your iPhone at any page of your logbook and capture it. Advanced text recognition detects and reads the hours and minutes from each row, and the app instantly calculates your total flight time. Every manual correction quietly trains a personal on-device profile of your handwriting, so recurring misreads fix themselves — the more you use it, the more accurate it becomes. Prefer extra power? Switch to the optional Cloud AI engine for even smarter reading of difficult pages. NIGHT TIME CALCULATOR Enter departure and arrival ICAO codes with your UTC times: your flight is drawn on a rotating 3D globe with real day and night. The night portion glows orange, with exact times and duration — computed with civil twilight. A 22,000-airport database works fully offline. SCAN IT — OR SAY IT Swipe sideways for the manual table. Dictate your times — "1 hour 35" — and watch them drop into the grid row by row. In a hurry? Type whole times in one field: "135" becomes 1h 35m. Totals update in real time, whichever way you enter your hours. KEY FEATURES Instant Logbook Scanning — your total flight hours in seconds. Smart Text Recognition — reads handwritten and printed times, even in imperfect lighting. Learns Your Handwriting — corrections train a personal on-device profile. Cloud AI Mode — optional cloud engine for the trickiest handwriting, with scan packs available. Night Time Calculator — day/night globe, orange night portion, times and duration. Logbook Backup — photograph your pages in landscape and keep a private photographic copy on your iCloud, exportable to PDF. Voice Dictation — speak your times in your language, up to 25 rows per page. Rapid Keypad Entry — one field, whole times: type, enter, done. Auto Table Detection & Manual Crop — the table is found automatically; a crop tool is there when you want control. Real-Time Totals — page and grand totals update as you scan, dictate, type or edit. 34 Languages — interface, dictation and guides localised for pilots worldwide. On-Device by Default — scanning, learning and totals run locally; no account needed. 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 paper logbook and wants a faster way to sum up flight time. SUBSCRIPTION, LIFETIME & FREE TRIAL Full access requires a subscription (monthly or yearly) or the one-time Lifetime unlock. Try it first, free: 3 Cloud AI scans, 5 minutes of dictation, 5 night-flight calculations and 3 backups — and manual typing in the table is free forever. Prices are shown in the app; subscriptions renew automatically unless cancelled at least 24 hours before the period ends, and can be managed in your App Store account settings. YOUR PRIVACY, GUARANTEED The camera is used solely to capture your logbook page, the microphone only for dictation, your location only to centre the globe. Scanning, learning and calculations run on your device. Cloud AI is optional: a photo is sent for reading only when you choose that mode and give explicit consent. No images or audio are stored externally. By downloading this app, you agree to Apple's standard Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
