## K4 Tools Description
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:
- Pro Versioncoming soon!
- LogTen Pro integration - tap a button and import all of your flight information with the tap of a button
- Crew Rest Alarms automatically set for selected break period.
- Custom Crew Rest break lengths
