Stop converting time in your head! See local, military, and UTC time (GMT and Zulu time zones) with a tap. Developed by pilots who can never remember the current UTC (GMT/Zulu) time conversion, Pilot Time instantly gives you the current time and date for your zone, plus UTC time. Pilot Time can: - Compare the time and date at your current location (in 12-hour format and 24-hour format) to UTC time. - Show the 3 time zones you looked at most recently, plus UTC time. - Quickly convert any past, current, or future time to or from any time zone (including GMT). And selecting time zones is easy: first find the continent, then the city you want. No more mental calculations. (The time is provided by your phone's operating system, not a central server. Time zones are taken from the IANA Time Zone Database.)

K4 Tools helps flight crews complete inflight fuel and time checks quickly and accurately — with calculators built around your current flight plan. Highlights: • Magic Scanner: Use the iPhone camera on support models to scan the FMS Position Report and auto-fill required fields. • Duty/Rest Calculator: See Max Duty End, Latest Legal Takeoff, and required rest based on crew size, sequence, and consent — with live remaining duty. • Crew Rest: Share break schedules and keep track visually on the crew break Timeline. • Fuel Checks: Verify pre‑flight fuel upload accuracy across multiple receipts. • Pre-flight weather verification via calculated ETA's at Departure, Destination, Alternate, and ETP Airports. • iPhone + iPad: Optimized for both portrait and landscape use on iPad — including mounted flight-deck configurations.. Limits and warnings appear when operational or contractual thresholds are approached or likely to be exceeded, so you can take corrective action early. Planned updates: - B777 flight plan support for both standard and ETOPS plans. - Crew Rest Alarms automatically set for selected break period. - Custom Crew Rest break lengths

Verdict
The clearest difference is rating: K4 Tools at 5.0 against Pilot Time's 4.5. K4 Tools also leads on update cadence (monthly vs every 6 months). Pilot Time's advantage is ratings volume (19 vs 1) and iOS requirement (13.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.
