WALT Calculator vs BlockTimePro

WALT Calculator is a toolbox containing many useful weather, location, and target related computations. WALT: Weather, Altitude, Lat/Long, Target Features: 1. Density Altitude Calculator Great for pilots, shooters, or weather enthusiasts, the WALT's density altitude calculator can provide a useful meteorological metric for comparing performance in differing weather conditions. For devices with a pressure sensor (iPhone 6 and later), DA can be automatically calculated from the device's own pressure sensor. 2. Field Elevation Calculator Know the ambient/station pressure and the alimeter setting/barometric pressure? Calculate your elevation above mean sea level with this calculator. Know your elevation but not your ambient pressure? With the field elevation calculator, you can calculate any of these three metrics! 3. Geographic Coordinates Converter Convert a geographic location from degrees, minutes, and seconds into decimal degrees, decimal minutes, or UTM. 4. Geographic Distance Calculator Find the distance between two points on the globe, given a set of geographic coordinates. 5. Target Calculator Designed primarily for shooting sports, the target calculator can compute distance to target, given target size and angle. Or target size, given target distance and size. This is a great complement to a mildot or MOA reticle optic.

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.
