BlockTimePro is a pilot-focused companion app designed to make filling out your aircraft’s official logbook easier, faster, and mistake-free. Instead of calculating flight and block times, day/night minutes, or fuel usage in your head, BlockTimePro generates it all automatically. You simply copy the results into your paper or electronic logbook with confidence. From flight planning to post-flight recording, the app keeps everything organized locally—so you can focus on flying while BlockTime handles the math. • Accurate Calculations for Logbooks: Enter show, takeoff, landing, and engine-off times in UTC; BlockTime auto-calculates flight and block times ready to copy. • Day/Night Breakdown: Automatically splits minutes between day and night. • Smart Time Suggestions: Sequential hints reduce typing errors. • Fuel Calculator & Costs: Track start, remaining, consumed fuel and compute uplift cost instantly (kg, lb, L, gal; USD/EUR/BRL). • Flight Planning: Distance, track, TAS, winds, groundspeed, ETE, dual ETA (UTC & Local) with date rollover. • Airport Database (Offline): Import global ICAO dataset for quick lookup (OurAirports). • Offline-First: Flight and plan data stored on-device; fast and private. • Free Trial then simple monthly subscription. Built for pilots who still write in the logbook—BlockTime does the math so you don’t make mistakes.
