EV Scooter Rental Mobile App

A clean app interface for booking, unlocking, and tracking shared EV scooters.

Mobile app interface mockups with purple and orange scooter app screens.

Overview

ZipRyde runs shared EV scooters across Kerala. Riders judge the service by the app: if finding, booking, or unlocking a scooter stutters, they walk. We built a cross-platform app where the core loop — find, unlock, ride, pay — feels instant.

The Challenge

The first version of the app suffered from slow map loads, failed unlocks at peak hours, and a payment flow that lost riders at the final step.

Our Approach

  1. 1

    Rebuilt the map and availability layer with aggressive caching and optimistic UI

  2. 2

    Redesigned the unlock flow with clear states for every hardware and network condition

  3. 3

    Streamlined payments to one screen with saved methods and automatic retries

  4. 4

    Instrumented every step of the ride loop so regressions surface before riders feel them

  • Payments complete in one screen with saved methods
  • Peak-hour load no longer degrades the booking experience
"From unlock to ride history, every screen feels instant. The app holds up during peak commute hours, which is exactly what we asked for."
