Stellar Delivery Date & Pickup

1. Good and reactive support. 2. The app is working as it said.
3. Very nice support
4. However, the app use custom field to record delivery time and delivery date. These fields are not standard fields. So other app cannot use the information to provide additional features (e.g. shipping cost calculation base on delivery date, or sending automatic rating emails after a delivery date, etc). So I might have to choose another app for my delivery schedule in order to integrate the data with other apps
