The latest version introduced significant feature updates, including CFR PART 117 coverage and schedule importer integrations, but the development cycle has remained stagnant for over three months.

Key takeaways for APDL - Airline Pilot Logbook
Where is it heading?
The aviation utility market is consolidating around specialized compliance tools, and APDL holds a stable position due to its deep regulatory integration. The current maintenance-mode cadence is sufficient for retention but leaves the app exposed to competitors that offer faster schedule-format support.
- The 111-day update gap indicates a mature product lifecycle, which provides stability but limits the ability to respond to new airline schedule formats.
- The specialized Part 117 legality engine provides a strong moat against general-purpose logbooks that lack deep regulatory integration.
The SWOT
- Part 117 legality engine creates high switching costs
- Schedule importer supports 200+ airline formats
- Expand payroll tracking to capture spreadsheet users
