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.

Verdict

The call

The clearest difference is in-app purchases: OK Mobility at none against Postmark's 1. OK Mobility also leads on iOS requirement (15.6 vs 17.6). Postmark's advantage is update cadence (every 2 days vs fortnightly). On price, ads and device support there is nothing between them.
