Flight logging for owner-pilots.
Log flights in seconds. Export a filled tax workbook with SIFL and Pure Business Use % already computed. Every figure follows the standard aircraft flight-log spreadsheet.
Log a flight in seconds
Type an identifier or a city — the app suggests matches from ~14,000 US airports. Nautical miles auto-fill from the great-circle distance.
Automatic tax math
Four-method comparison, SIFL imputed income, and Pure Business Use % computed with the exact formulas from the standard workbook.
Export your data in two taps
Download a filled Excel workbook or email it to whoever you like. Formulas are preserved so the sheet recomputes on open — everything you exported is editable.
Every figure is for review
Jett Log is not tax, legal, or accounting advice. It reproduces the calculations from the standard aircraft flight-log workbook so the numbers you export match what a tax professional expects to see.
