Check out our new iOS app on the Apple App Store. The Android version should be approved soon on the Google Play Store. Both have significant performance improvements over the web app.
Going native is the right move for a travel tracking app where performance and offline capability matter. The web app might work at your desk but travelers need something that's fast and reliable when they're standing in front of a monument trying to log their visit.

That consistency is exactly what builds trust with users who want to know their travel data will still be there in five years.
