Klang Valley · Fitness app reviews

See which sensor moments athletes glance past — and which ones earn a decision.

Sensor Vertex Core studies how people interact with heart-rate prompts, GPS maps, cadence cues, and recovery scores inside fitness apps. We deliver ranked findings your product and coaching teams can act on before the next release.

Flagship work: Sensor Interaction Audit for fitness product teams

What teams ask us to examine

Engagements stay close to workout reality: prompts mid-set, post-session maps after humid runs, recovery numbers that argue with the training plan.

Sensor Interaction Audit

We examine heart-rate prompts, GPS maps, cadence cues, and recovery scores inside your fitness app to show where athletes glance, skip, or act — then deliver a concrete change brief for your product and coaching teams.

Flagship: Sensor Interaction Audit

A 12–18 business day review of up to six sensor-facing flows. You receive annotated walkthrough notes, a friction map, and a ranked change brief — not a generic analytics dashboard pitch.

Evidence from recent engagements

Clients mention specific screens, timing problems, and follow-up work — not vague praise.

“The audit showed our post-run map was asking for a share action before athletes had even looked at their splits. We moved share later and support tickets about ‘confusing summaries’ dropped in the next release cycle. I still wish we had scoped sleep screens in the same pass — that will be a follow-up.”

“Watching a live strength session with their analyst made the dismiss taps obvious. Our heart-rate banner was firing during the concentric phase; nobody had time to read it.”

Built around Malaysian training contexts

Outdoor GPS sessions in heat, stop-start city routes, and bilingual coaching strings show up in our reviews because they show up in real athlete weeks here. We work remotely across the region and can meet in the Klang Valley when a working session helps.
