I led end-to-end UX for the Field Services App — a mobile and iPad product that gives service technicians a fast, intuitive way to see today’s jobs, prioritize tasks, and add job details on the go. Built for Scorpion’s field-service clients.
02 The challenge
The goal: give technicians a fast, efficient way to complete tasks and add details for any job that needs doing — on whatever device they have in hand between calls.
Field technicians aren’t sitting at a desk. They’re between jobs, one-handed, often in a hurry. An app they have to think about is an app they won’t open. So the real question wasn’t what features to add — it was: how do we make this intuitive and dead-simple to understand?
Lead every screen with the two things a tech cares about — what’s open and how they’re doing — so the app answers “what’s next?” before they even scroll.
03 Process
No budget for a full user study — so I worked directly with stakeholders to pin down the information technicians actually need, and ran a competitive analysis of how task-completion apps help people get things done.
of users with customizable dashboards & prioritization complete tasks faster and more accurately.
of users who get real-time updates & notifications stay more engaged and motivated through a task.
Competitive analysis across to-do lists, global & specific search, and tag systems — to understand real user behavior before designing.
Low-fidelity wireframes across several approaches, tested and iterated throughout the product lifecycle.
We shipped Approach B — surfacing highlight insights about a tech’s tasks, so they know what to keep going on and what needs immediate attention.
04 The solution
The shipped app opens on a prioritized view of today’s work — open tasks and close rate up top, a scannable task list below, and quick-add always within thumb’s reach.
Open tasks and close rate lead the home screen — the tech’s status at a glance.
Tasks sorted by priority and deadline, with tags, expandable cards, and subtasks.
A floating action button to log a job or detail without breaking stride.
Tabs for Today / Upcoming / All, expandable task cards, priority tags, and subtasks — designed for one-handed use between jobs. The FAB keeps “add a task” one tap away, anywhere.
Real product screens from the shipped app.
The same system, re-laid-out for the bigger screen — a fuller dashboard for techs and dispatchers who work from a tablet.
05 Impact
The Scorpion mobile app grew with more field-service clients every month — and, more tellingly, technicians kept opening it.
A healthy DAU/MAU ratio for a niche field-service tool used on the job.
Nearly 1 in 5 users who downloaded the app open it every single day.
Nearly half of all users return at least once a week — adoption climbing monthly.
06 Reflection & role
I led UX end to end for both mobile and iPad — clarifying business goals with the product manager and director of design, building flows and wireframes, UI and interaction design, prototyping, presenting to stakeholders, and refining and exporting designs for development while working closely with engineers on edits.
Constraints sharpen the work. No research budget meant leaning on stakeholders and competitive analysis — and being ruthless about what mattered. A small scope made every decision count.
Design for the moment of use. A technician between jobs doesn’t read — they glance. Leading with open tasks and close rate, and putting “add” under the thumb, is what made the app feel intuitive.
