Pheezee

Drove 65% test completion within the constraints of an existing UI.

Five Pheezee app screens: live monitoring, a session summary, and body-part selection.

Pheezee had the tools. Physiotherapists just weren't using all of them.

Pheezee β€” a biofeedback device and app for physiotherapists β€” already had plenty under the hood. The challenge was connecting those capabilities to the specific needs of Ortho, Neuro, Geriatrics, and beyond. The leadership team introduced Special Tests to bridge that gap, and my job was to turn that direction into an experience that actually worked. Was the gap closed? Was the design helpful? Could more specialized physiotherapists get the most out of Pheezee? Hmm... πŸ€”

A confused physiotherapist plus Special Tests equals one still asking β€œdid it work?”.

The direction was set. Turning it into something real was mine.

Leadership had the idea and the name. Everything after that β€” figuring out what physiotherapists and patients actually needed, researching, sketching, testing, and shipping the final design β€” was on me, start to finish.

The UI was already live. I had to make Special Tests belong.

No blank canvas β€” just a working app, and a job to make Special Tests happen inside it, without touching what was already live. No new navigation, no new visual language. Just the existing pieces, made to work harder. A far more honest test of whether the thinking actually holds up than starting from scratch ever would be.

How I actually figured this out - Interviews kept falling through, so I stopped relying on them alone

  • CUX
  • USER INTERVIEW

Scheduled conversations got cancelled more often than they happened. So I started observing alongside physiotherapists too, filling the gaps conversations left behind. One afternoon waiting on a doctor who never showed taught me more than the interview would have β€” physios move between patients with almost no spare seconds.

What the research actually surfaced

  1. 1

    Physiotherapists weren't confused. They were rushed.

    They knew the right muscle, movement, and angle. They just didn't have fifteen seconds mid-session to build it from scratch β€” so the rush won, not the confusion.

  2. 2

    One App, Two Different Comfort Levels, No Splitting

    Veterans wanted speed, no hand-holding. Juniors needed guidance, even unspoken. Spoon-feed the senior, they'd tune out. Leave the junior unguided, they'd hesitate. It had to flex both ways.

  3. 3

    Everything on the page meant nothing stood out

    General tests showed every option, always β€” complete, but mostly beside the point. Physiotherapists didn't need more choices. They needed the screen to already know which ones mattered.

  4. 4

    A graph doesn't encourage anyone mid-exercise

    When a patient extends their knee, a flat line on a graph doesn't say β€œyou're doing great.” Progress needed to feel visible, not just measurable.

Research Didn't Just Find a Problem. It Found a Gap Nobody Named.

I went into the field to understand what was getting in the way of the existing general tests β€” so we wouldn't carry the same problems into Special Tests. But somewhere along the way, physiotherapists started asking for something else: condition-specific tests. Which, funnily enough, was exactly what we were there to build.

Yeah, small world!!

I took the finding back to the team. Turns out, the demand was real β€” and it opened up a much bigger opportunity than we expected.

Special Tests became a premium feature on its own.

Before pixels came scribbles.

  • minimalist
  • easily understandable
  • one template, for all the tests
  • less pages
  • more detail? no
  • nav shouldn't make anyone think
  • Versatile enough to accommodate other upcoming coming tests

These weren't meant to look pretty. They were made to help me visualize the UI β€” exploring layouts, screens, and flows quickly before turning the ideas into the actual interface.

Five hand-drawn paper sketches of Pheezee screens, including live monitoring and body part selection, annotated β€œThese made sense in my head”.

Think-aloud testing, with the team I got.

Real user testing wasn't on the cards, so I tested with hardware engineers, production folks, and people with zero physiotherapy background. If they could navigate it without getting stuck, I knew I was onto something. A few rounds. A few fixes. A very different final design.

Lots of iterations. A few wrong turns. Eventually, the final UI.

From the first rough screens to the polished experience, the design went through plenty of rounds β€” refining the flows, hierarchy, and details until everything started making sense.

A quick note before you scroll: none of this was designed to show off. It was designed to disappear into a physiotherapist's workflow and quietly make sense to the patient on the other side. If it looks simple, that's the point. Not an accident.

From Problems to Solutions

Here’s where each problem meets its solution β€” a quick look at the decisions behind the screens and how they came together.

1234

Physiotherapists weren't confused. They were rushed.

Every patient meant manually picking side, position, movement, reps, EMG range, and angle β€” all before starting.

The old general test screen, with side, position, movement, muscle, reps, EMG and angles all set by hand.

Select the condition, and the right combination is already there.

One selection now does the work six used to.

One App, Two Comfort Levels, Somehow Both

Same detail, same instructions, whether it was someone's first test or their hundredth.

The old general test screen, identical for a first test or a hundredth.

Guidance stays hidden until asked for.

Veterans get a clean screen. Juniors get a teacher, one tap away.

30s Partial Curl Up test setup with the guidance collapsed, asking only for the dominant side.
The same test with guidance expanded: sensor placement picture, why the test matters, and step-by-step instructions.

Encouragement, Not Just Data

A number or a graph line, mid-exercise β€” accurate, but meaningless to a patient just trying to finish.

The old Live Monitoring screen, labelled Old Design: a range-of-motion dial, angle and rep fields, and an EMG graph.

A stack of arrows that lights up as you move.

No numbers to read. Just proof the next rep counted.

Grip Strength Live Monitoring with a progress ring around the hand illustration, contractions and peak EMG.

General Tests Showed Every Option, Always

Every field, every setting, every time β€” regardless of what the case actually needed.

The old General tests screen: side, position, movement, muscle, reps, max EMG and angles all set by hand.

Choose the condition, see only what applies.

Pick Ortho, Neuro, or Geriatric β€” the screen adjusts itself.

Did it actually work?

Special Tests brought in new users who came for this feature, and physios ran more tests because of it. It launched as a premium feature, and revenue grew once it went live. Here's how it played out in numbers.

  • +16%New user acquisition
  • +23%Task Completion
A confused physiotherapist plus Special Tests equals a happy one: β€œit worked”.

A few things I'd carry into the next project.

  • Good design isn't always about adding something new.

    Sometimes, it's about helping people understand the value of what's already there.

  • Even without the field, I could still get closer to users.

    I learned to find different ways to understand their needs, behaviours, and the problems they were facing.

  • Not everything needs fancy UI.

    Sometimes, the best interface is the one that quietly gets the job done.
