This is by far the most comprehensive travel organizer program. Ive used it for years, tried all the others, but always come back to this for its options and easy UI. Others have mentioned no sync, and I totally agree. There is no excuse for not having a simple iCloud sync to keep your devices automatically up-to-date. You can work around that by syncing it manually to a free Tripit account, and then downloading to another iOS device, but here is where the major flaw is. Even when you link this to your Tripit account, it keeps dropping that link and asks you to sign in to Tripit again. Each time you do, it automatically downloads from Tripit and overwrites whats on Travel Tracker for your iOS device. Because it forgets about your link frequently, you often end up entering a bunch of info into Travel Tracker, then you want to upload it to Tripit, but you cant because it lost your link. Sign in and it overwrites all the work you did with the older stuff on Tripit. This could all be solved with a simple auto sync function.
