02 / Process

Benchmark, design, test, adapt, build

  1. 01

    Benchmark

    Studied Fisher-Price, Mamaroo and Sleep Monitor apps for control, safety, usage data and presets.

  2. 02

    High fidelity first

    Went straight to high-fidelity Home, Statistics, Profile and Saved Control screens.

  3. 03

    Test and refine

    Tested with users after every design and iterated on their feedback and usage data.

  4. 04

    iOS, then Android

    Designed iOS first, where most users were, then Android on Material Design guidelines.

  5. 05

    Build with devs

    Checked technical feasibility with devs throughout, through to the beta app.

Home screen, simplified after testing

After each user test, we simplified Home with sliders and large buttons.

04 / Blocker and recovery

Blocker and recovery

Blocker

Firmware, load speed and a committed deadline

The app had to integrate with the hammock's physical firmware and release inside a committed timeline. Load speed was also a problem on some screens.

Recovery

Recurring dev check-⁠ins and three trade-offs

Some screens became PWA for load speed, Advanced settings became a scalable chart instead of a bar, and pop-over triggers followed each platform's guidelines.

Recovered by me and the team

05 / Impact

From manual hammock to smart device

The app put the manual hammock under phone control, and Moonboon got its first admin panel for devices, users and staff.

Learnings
  • Finish the firmware before the app; it saves post-production time and cost.
  • Ship fewer features: overload slows load times and drives users away.
  • Build a design system early, so the work stays efficient and easy to scale.
