Redesigning Lantum App

Challenge
Healthcare clinicians were struggling with the existing Lantum mobile experience. Originally designed for locum doctors to book ad hoc shifts, the app hadn’t evolved to support the realities of rota-based clinical work.
I led the redesign of the core scheduling experience to deliver glanceable insights, clearer shift differentiation, and actionable detail, resulting in measurable increases in engagement and adoption.
The Problem
Clinicians often knew their long-term rotation patterns, but relied heavily on a live calendar to manage frequent last-minute changes. Many hospital wards were still using static Excel rotas, error-prone systems that increased stress and reduced trust in schedules.
Beyond work logistics, the schedule was a life-management tool. Clinicians needed quick answers to questions like:
-
How many night shifts am I working this month?
-
Which weekends am I on call?
-
What’s my overall shift pattern?
The existing experience created cognitive overload rather than clarity.

Research & Validation
I conducted qualitative research interviews and usability testing with clinicians across specialties.
Key insights:
-
Scanning speed mattered more than information density.
-
Colour cues were heavily relied upon under time pressure.
-
Long-term pattern recognition (e.g.nights, weekends) was as important as daily details.
-
Users needed confidence that the schedule was accurate and up to date.
Low- to mid-fidelity prototypes were tested iteratively to validate hierarchy, grouping logic, and colour semantics.

Design Exploration
I translated research insights into designs focused on:
-
Clear visual hierarchy
-
Meaningful and consistent colour coding
-
Predictable grouping of shifts
-
Progressive disclosure of secondary details
The goal was not to add more information, but to reduce cognitive load while increasing trust and clarity. I also improved the UX by enabling clicking directly from calendar into the shift.
Usability testing validated which visual signals clinicians relied on most when scanning under pressure, particularly shift-type colour coding and weekend grouping.
Final Design
The redesigned schedule introduced:
-
Instantly recognisable shift type
-
Switch between calendar and list view
-
Reduced visual clutter
-
Actionable shift details without overwhelming the primary view
-
Improved long-term pattern visibility
Secondary information was progressively disclosed rather than competing for attention, supporting both quick glances and deeper planning moments.
Impact
-
Monthly individual user sessions increased from ~1,000 to over 9,000
-
Strong qualitative feedback from clinicians citing improved clarity and reduced stress
-
Increased trust in the live rota
-
Reinforced the importance of designing for cognitive load, not just information completeness
Lantum rebranded for the new user group with these designs and functionality as a huge draw for expanding in hospitals.
