Seros mobile application

The product needed a mobile experience for managing and verifying smart lock access: device details, code flows, and scheduling (hourly, multi-day, vacation) without overwhelming users who are often on the move.

From product requirements, the design had to:

• keep a calm neutral base with one confident primary action color
• make unlock, codes, and schedules scannable in a few seconds
• scale from a single device to many properties without clutter

I worked from scratch with stakeholders to turn requirements into flows, then iterated on typography, spacing, and component patterns until the UI felt obvious for first-time and power users alike.

The experience was organized around one clear job at a time:

Generating an access code should be fast and effortless — and the user should always feel confident that access is controlled and won't end up in the wrong hands.

Key directions included:

• device-first hierarchy with secondary actions tucked behind clear affordances
• scheduling patterns that read as timelines, not spreadsheets
• consistent feedback when codes change or access ends
• proactive battery monitoring — rather than polling the device continuously, the app estimates remaining runtime and surfaces a warning early enough to act, without draining the user's phone

The mobile interface was designed and shipped from scratch — from early flows and wireframes through final UI and handoff. The app launched with full support for device management, access code flows, and flexible scheduling across single and multi-property setups.
