Operation, logistics and production tracking Mobile App Development

We operate a residue recovery business across 12 different locations.
At each location, labour manually cleans and collects residue in sacks or load direclty in trolleys.

We need a cloud-based mobile app (Android first) for supervisors to enter daily production, expenses, and stock movement, and for owners to monitor performance across all yards via dashboard.

This is an operations tracking app (similar to logistics/production tracking apps).
