Key takeaways for Crew Time Calculator
Where is it heading?
The aviation utility market requires high-trust, frequently updated tools to remain relevant. Crew Time Calculator currently functions as a static reference, which is sufficient for now but leaves the user base exposed to potential compliance errors if the developer does not resume an active update cadence.
- The 93-day update gap confirms a maintenance-only posture, which limits the app's ability to adapt to future Part 117 regulatory changes.
The SWOT
- Single-purpose utility design reduces cognitive load for pilots needing rapid compliance checks
- Automated logbook syncing could create a defensible barrier against manual-entry rivals
Next best moves
Audit calculation logic against current Part 117 updates because the 93-day update gap risks regulatory drift → maintain user trust

Read the full takeBottom line
The utility serves a clear compliance need, but the lack of development activity threatens its long-term viability as a reliable regulatory tool. Maintaining the current logic is sufficient only if the developer commits to a rapid response cycle when regulations shift.
