Everything a tracker should be. Nothing else.
A countdown first
Every package leads with the number of days left. The details are one tap away.
No account
Nothing to sign up for. Carton has no user database, so there's nothing to leak.
Straight from UPS
Carton reads the same tracking page you would, so the date matches what UPS says.
iPhone, with iCloud
The app keeps your list in sync across your devices through your own iCloud.
