An Android warehouse management app used daily for picking, packing and transfers on industrial devices.

Key result
~30%
improvement in goods receiving

Case studies are anonymised: client names and data are omitted, and any screenshots use synthetic data.

Context and problem

The operation needed to digitise warehouse work: receiving, picking, packing and transfers, done on the floor from handheld devices.

The app had to work with industrial scanners and label printers, and let operators scan items in batches.
