Not a business expense tool — a travel companion. **Your whole trip, one timeline** Every flight, hotel and event in the order it happens. See your trip at a glance instead of digging through emails and screenshots. **Build your trip with AI** Paste a flight confirmation email and Postmark reads it for you — flight numbers, airports, dates and times, filled in automatically. **A diary that keeps up with you** Journal entries, expenses, reminders and events — colour-coded and tied to the day they happened. Look back on where you were and what you spent, day by day. **Live flight status** For flights departing soon, see gate, delays and cancellations at a glance, so you're never caught out at the airport. **Made for travel** - Multi-country trips with per-country detail - Track expenses by country and currency - One-way sync to your Apple Calendar - Share a trip as plain text to anyone — no app required - Voice-to-text journalling on the go **Private by design** Your trips, journal, photos and expenses are stored on your device and synced privately through your own iCloud.
