What's New in Zeitfarer

1.1.1

November 5, 2026

What's new in Zeitfarer 1.1.1: - Readiness check: it now shows at your report time. It was showing at your van time. - Readiness check: it no longer warns about a wake the plan set from your own Get-ready time, or about a suggested nap you did not take. A wake you logged now reads "You woke" instead of "This plan wakes you." - Get ready: layover and commuter hotel cards now show when your Get-ready time has you up, for example "Up by 08:15 AMS, 1h 30m before you leave." Questions or feedback: support@zeitfarer.com or (720) 281-9703 (phone or text).

Fatigue management improved

A solid app that accounts for various factors real-time (hotel arrival, delays, length of time actually sleep, etc) and adjusts your recovery plan accordingly. I experienced improved sleep quality and fatigue management on my first trip. As always, some fine-tuning to what works for each person may be needed but it has certainly helped me.
