Very specific request handling app that I was working on when freelancing
- Operator sends specially-crafted SMS message to the worker's telephone
- Application intercepts this SMS as it was sent from number in its' settings
- Application then creates request entity suitable for processing (address, date etc.)
- Worker clicks on request when it's completed and selects from options (completed, moved, denied)
- When worker clicks "Ok", application deletes/moves request according to selected choice
- Application sends crafted SMS with report and commentary from worker back to operator
