5 OneTracker
One Tracker stands out from many tracking apps because it allows users to forward shipping notification emails to a unique email address. This unique address will automatically add packages to the app so you don’t have to waste time copying and pasting.
The app has a barcode scanning feature letting you scan a package’s barcode instead of entering a tracking number. Of course, users can also enter a tracking number manually if needed.
Users can opt to receive push notifications for every major step of a package’s delivery. All major worldwide carriers are supported, and new carriers are added with time. The app and all of its features are free.
