Track123 Order Tracking

Great app, I have no trouble to setup and customize it. The guide they has post on line is easy to understand and no programmer is required. The only thing I wish they can improve is live update on delivery status with carrier at same time: I had a package delivered by Canada Post and send me a notification says the package has been delivered, but, the app was not able to update right way.
Overall, the update history has actually more details than Canada Post. This is a really great app. Totally recommend it.
