Danube International Washer-Extractor keeps the record of washes done in the machine with the timestamp. The app is made to calculate total kgs of washes done by machine to report the laundry owner so that he can cross-check it with revenue collected.
The washer exposes its debugging log files and wash records over a USB port. The app parses those logs into a readable wash history so the owner can cross-check it against the offline register the manager maintains — if 100 kg was washed but only 80 kg recorded, the missing revenue is now visible.
