Overview

Trego is a mobile-first tool for field teams. Workers needed a fast, focused way to see their day, accept jobs, and capture work on-site — without wrestling with desktop software.

We built the cross-platform app around a clear daily and weekly view, with auto-scheduling, voice capture for on-site notes, and automation digests that keep crews coordinated with minimal admin.

Streamlined daily scheduling for field teams.

  • Auto-scheduled jobs
  • Voice capture and notes on-site
  • Daily and weekly job board
  • Client and crew coordination
  • Job automation digests
  • Multi-language (EN · PT)
