If I had to request changes it would be to include other carriers such as Singapore, Polish and Chinese postal info. This is available on other sites but this would be most powerful if everything was in one place. Very good app! Thank you. Au contraire jhabite en France et ça marche. Pas tout les service en France permis davoir un suivi. Le plus part notifie que en livraison donc normale le traçabilité ne marche pas!
