The tools I couldn’t find in an EFB
Not another logbook
Best-fit burn rate per oil cycle with ±0.25 qt dipstick error bars and a per-flight trend.
Digitize your POH charts once, then get takeoff, abort, landing, and climb numbers for today's density altitude, wind, and runway - pulled from a live airport and forecast.
Author once, then export to Garmin G3X .ace, an offline phone runner, and a printable kneeboard card - with a checklist linter and teaching layer.
ADs, inspections, currency, and databases counted down on two clocks - calendar and tach or Hobbs - with a projected due date from how you actually fly. Free.
Track open squawks by status - outstanding, monitoring, question, addressed - with photos and links to the flights they turned up on.
A shareable snapshot of where the airplane stands - clocks, ADs, inspections, squawks - ready in a click for your mechanic, a checkride, or a new CFI.
Cleared for Takeoff

Example · Cessna 177RG Cardinal
The Hangar isn’t seeded with mock data. It’s the founder’s own Cardinal RG: real maintenance records, real AD history, the actual checklist flown from the left seat. If it survives N89SF’s annual, it can survive yours.
