Stride(Concept)–Web&MobileAppRedesign
Stride lends free phone batteries from boxes in French bars, campuses and cinemas, and pays for it with advertising aimed at 18 to 25 year olds. This is a concept: my own redesign of its brand expression, website and mobile app. It isn't Stride's live product. The website is a working build, and the app is a functional prototype running on demo data with no backend.
The Idea
Stride talks to two very different audiences: brands buying attention, and students at 2% battery. Gen Z tunes out classic advertising, but it remembers who saved its evening. The concept leans into that: a brand as loud and useful as the service, with one visual language from a campaign pitch to a bar counter.
The Website
Built around two audiences— Four pages separate advertisers from venues: how campaigns work, why a useful service beats an interruption, how a venue joins, and who's behind it.A motion system with attitude— Hard shadows, stacked colour layers and window-frame cards, driven by GSAP and Lenis: pinned how-it-works steps, a sideways gallery of real locations, stacking case cards and an animated map of France. Reduced-motion settings are fully respected.Just as loud on a phone— Every pinned and horizontal scene was reworked for mobile, with fluid stat sizes and larger tap targets, so the personality survives on the screen students actually use.The Mobile App
Thirty-six screens, one complete loop— Onboarding, sign-up, map, Stridebox details, QR scan, unlock, battery timer, return, confirmation, offers and activity. It's built in Expo and React Native and runs on a real phone, with the real camera scanning.Honest about the deposit— The moment most likely to scare a student gets the clearest screen: a card imprint that is never charged if the battery comes back within 48 hours.Failure states designed too— An empty box, a failed unlock and a city outside the service area all have their own screens, because a phone at 2% is the worst time to hit a dead end.The Brand Book
The whole concept is documented in a 44-page brand book covering logo, colour, type, tone of voice, motion and applications, with a showreel to present it.
Concept work. Campaign figures visible on the website come from Stride's own presentation and aren't results of this redesign.
