Test Device ID as a unique login without getting peoples email to signup & login (old school) since Devices are already unique.
Create a route planner for myself (to get all recycled bottles with the short amount of time) and the people to use for free for route delivery based on Device ID.
Tired of signup for free stuff only to get DUCK in the end that you need to pay. Once I'm done people will be able to Add (Addresses for google map directions), Save, Remove, Upload (a csv file - list of addresses), Add Notes, Drag and Sequence & Colour Code.
