IMPROVED: Change your synced calendar anytime Previously, the calendar you picked on first use was locked in. There's now a "Change calendar" option always available next to the Sync button, so you can switch calendars whenever you need to. FIXED: Long westbound Pacific routes (e.g. US West Coast to East Asia) were sometimes showing blank flight hours after syncing, due to how the combination of time zone change and international date line crossing affects the local arrival date. Block hours now calculate correctly for these routes. ### 1.2 — 2026-09-18 NEW: Flight Duty Period (FDP) tracking Track your rolling 60-hour FDP limit (60 hrs in any 168 hours) alongside your existing 100-hour flight time tracking. When you sync from Calendar, the app automatically works out each duty period's report and release times — using your actual published schedule, not an estimate — so this requires no extra manual entry for most trips. A manual FDP field is also available when logging a day by hand. IMPROVED: Much broader airport coverage Timezone-aware block time calculations now cover over 360 airports across the United, American, and Delta route networks — not just a handful of common ones. IMPROVED: Daily Headroom calendar Simplified to a single toggle for the 95-hour trading buffer instead of manual entry, and the underlying date calculations are now accurate no matter what timezone your device is set to — including while you're traveling internationally. FIXED: Chart data box now dismisses properly when tapped again, and the flight log no longer shows placeholder rows for report-date FDP entries that don't have their own block hours. ### 1.1 — 2026-09-11 NEW: Sync your schedule directly from your Calendar app If your airline publishes your schedule to your device's Calendar app, FAR 117 Tracker can now read it directly — no more saving and re-importing a PDF every time your schedule changes. Tap "Sync from Calendar," review what it finds, and you're done. Re-sync anytime — it automatically updates changed trips and removes any that were dropped from your schedule. NEW: Two-gauge dashboard See your rolling 28-day total and how many hours you have available to pick up, side by side at a glance. NEW: Daily Headroom calendar A full month view, color-coded by how much flying you could safely add on any given day — built for bid planning. NEW: 95-hour trading buffer toggle Switch between the full 100-hour FAR limit and a 95-hour buffer with one tap. Plus accuracy improvements to timezone handling and the schedule-review workflow. ### 1.0 — 2026-09-10 No release notes. ## Apps similar to FAR 117 Tracker (100hrs/672) | App | Rating | Price | Category | | --- | --- | --- | --- | | [Cabin Count](https://appshunter.io/ios/app/cabin-count/id6759534462) | 5.0 (1) | $1.99 | Utilities | | [Crew Time Calculator](https://appshunter.io/ios/app/crew-time-calculator/id6775395605) | — | Free | Utilities | | [AirlineCalc](https://appshunter.io/ios/app/airlinecalc/id6743721054) | 1.0 (1) | Free | Utilities | | [AutoBotEV](https://appshunter.io/ios/app/autobotev/id6463710756) | 1.0 (3) | Free | Utilities | | [Flight Duty Calculator (FAA)](https://appshunter.io/ios/app/flight-duty-calculator-faa/id830723551) | 1.0 (1) | $2.99 | Utilities | | [CRJ Virtual Panel](https://appshunter.io/ios/app/crj-virtual-panel/id1506804239) | 4.4 (12) | $19.99 | Utilities | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
