COMPANION APP

As part of a broader health platform ecosystem, we needed to design a companion app that connects a Bluetooth-enabled health band or smartwatch to a user’s smartphone, ensuring health data flows seamlessly into the main Health & Longevity App.

PROJECT OVERVIEW:

Product: Bluetooth Companion App

Domain: Digital Health

Role: UX Lead & Designer

Users: Longevity App Users

Platforms: iOS mobile app, Wearable device

Focus: Delivering a frictionless bridge between wearable and platform

Tools: FIGMA, Confluence, JIRA, Maze

My Role:

  • UX research and journey mapping

  • Interaction design and system state modelling

  • Wireframing and high-fidelity UX design

  • Collaboration with engineers on BLE constraints and background syncing logic

  • Iterative usability testing and refinement

The challenge was to make the connection process intuitive and reliable, given that Bluetooth pairing can often be a major source of user frustration. My role focused on understanding the mental model of users around device connectivity, and translating that into a guided, reassuring flow that built confidence and minimized setup friction.

Through iterative design and testing, the app was shaped to:

  • Simplify the device pairing journey with clear, step-by-step guidance and visual feedback.

  • Provide transparent connection states (e.g., “searching,” “connected,” “syncing”) to reduce uncertainty.

  • Ensure background data synchronization so users never needed to manually manage transfers.

  • Balance technical complexity (Bluetooth, background permissions, data encryption) with a human-centered experience that felt effortless.

The result was a lightweight, dependable companion app that acted as the invisible bridge between wearable and platform — empowering users to focus on their health insights, not on the connection behind them.

THE PROBLEM:

Bluetooth pairing is one of the most common points of friction in connected health products.

  • Failed pairing attempts

  • Unclear connection states

  • Confusing permission requests

  • Manual data syncing frustrations

THE DESIGN GOALS:

Users experience:

Simplify the pairing journey with guided, step-by-step flows

Provide transparent connection states to reduce uncertainty

Create visual reassurance during device discovery and syncing

  • Firmware versions

  • Background permissions

  • BLE protocols

  • Encryption layers

Automate background synchronization & connection

Users don’t understand:

Balance technical reliability with human-centred design

Users expect:

“It should just connect”

The Process

  • The Mental Model

    We explored how users think about “connecting a device.”

    » Key insight:
    Users view pairing as a single action, not a multi-step technical process.

    This informed a linear, guided setup flow rather than exposing system-level Bluetooth complexity.

  • Mapping System States

    Bluetooth pairing includes multiple backend states:

    Bluetooth disabled » Searching » Device discovered » Authenticating » Connecting » Connected » Syncing » Firmware update available

    We translated these technical states into clear, human-readable feedback.

  • Designing for Reassurance

    To reduce anxiety during setup, we introduced:

    » Animated signal indicators during search

    » Clear success confirmations

    » Visible battery levels

    » Device imagery for confirmation

    » Transparent firmware update prompts

    Each screen answered:
    “What’s happening right now?”

User Journey

Primary User Goals:

  • Reduce uncertainty during wait time.

  • Prevents accidental pairing and builds confidence.

  • Technical complexity remains invisible.

  • Data sync runs automatically in the background.

Key Design Considerations

  • Progressive disclosure to avoid cognitive overload

  • Clear state-based messaging

  • Visual confirmation to reduce pairing anxiety

  • Automated background syncing

  • Firmware update surfacing

The goal was to make complex infrastructure feel effortless.

 

The Final Product

Available on:

The result was a lightweight, reliable companion app that:

  • Reduced pairing friction

  • Increased user confidence during setup

  • Enabled passive, secure data flow

  • Strengthened trust in the broader health ecosystem
