Background

Making EV charging accessible to everyone, not just app users.

ChargeNow Indonesia operates a network of portable powerbank rental stations across Indonesia — enabling people to charge their devices on the go by scanning, renting, and returning powerbanks at any station.

The existing product was a native mobile app. While functional, it created an unnecessary barrier: users had to download and install an app before they could rent a powerbank. For a service designed around impulse convenience — you need a charge right now — asking someone to visit an app store, download, create an account, and then scan was too many steps.

ChargeNow needed their platform available instantly, on any device, with no install required.

Challenge

Porting a native mobile experience to the web without losing what made it work.

The core challenge was not just rebuilding the app as a website — it was preserving the speed and simplicity of the mobile experience in a browser environment.

  • Camera and hardware access — The existing app relied on native device features for QR code scanning at stations. The web version needed to replicate this using browser APIs without sacrificing scan speed or reliability.
  • Real-time station data — Users need to see live availability of powerbanks at nearby stations. The web platform had to maintain the same real-time data connection and location-based station discovery.
  • Seamless payment flow — The rental and payment process had to feel as fast on web as it did in the native app — no page reloads, no redirects, no friction.
  • Responsive across all devices — The web app needed to work flawlessly on phones (where most users would access it), tablets, and desktops — adapting layout and interaction patterns for each screen size.
Approach

Designing web-first, then testing until every interaction felt native.

We started with a comprehensive UX audit of the existing mobile app — mapping every user flow, identifying what worked well, and flagging what could be improved in the transition.

Research-driven redesign

Rather than doing a 1:1 port, we used the platform shift as an opportunity to simplify. We conducted usability testing on the existing app to identify pain points and incorporated those findings into the new web experience. Redundant screens were merged, navigation was flattened, and the core flow — find a station, scan, rent, return — was streamlined to the fewest possible steps.

Web-native interactions

We leveraged modern browser capabilities to handle QR scanning, geolocation for station discovery, and push-style notifications — all without requiring an app install. The interface was designed to feel app-like in responsiveness and speed while being accessible through any browser.

Responsive-first architecture

The UI was designed mobile-first — since the majority of users would access it from their phones — then progressively enhanced for tablet and desktop. Every component was tested across screen sizes to ensure the experience felt intentional on each device, not just "scaled up."

Iterative usability testing

We ran multiple rounds of usability testing throughout development — testing the QR scan flow, the station finder, and the payment process with real users. Each round surfaced specific friction points that were addressed before launch.

Result

A powerbank rental that's now as instant as the charge it delivers.

The new ChargeNow web app launched as a fully responsive platform accessible from any device with a browser. Users can now find a nearby station, scan the QR code, rent a powerbank, and pay — all without downloading anything.

The transition from native app to web app eliminated the single biggest barrier to adoption: the app store download. New users can now go from seeing a ChargeNow station to having a charged powerbank in under 60 seconds.

The web-first architecture also unlocked faster development cycles for the ChargeNow team — new features and fixes can be deployed instantly without waiting for app store review processes.

  • Removed app download barrier — users access the service instantly via browser
  • Simplified the core rental flow from 5 screens to 3
  • Full responsiveness across phone, tablet, and desktop
  • Faster iteration cycles with web-based deployment
