Description
A branding, iOS app, and launchpage project developed with Figma and React Native.
Leg Day is a social app meant to connect people at the gym. As a Founding Engineer, I was responsible for the frontend development and branding for this application. Leg Day is a social app meant to connect people at the gym. As a Founding Engineer, I was responsible for the frontend development and branding for this application — shaping how every member experiences the product from the moment they hear about us to the moment they meet someone in real life.
On the mobile side, I designed and built the entire new-member onboarding flow in React Native (Expo), including an interactive tutorial that teaches users how mutual matching works before they ever swipe on a real profile. A central proponent to this app is a hands-on Discovery → Rolodex demo: a guided sequence of animated profile cards that the user shakes, swipes, and "matches" with, all driven by gesture and Reanimated 3 transitions. Beyond onboarding, I created a profile editor, the gym check-in experience, the gesture-driven card stack, the visibility controls that let members decide who can see them, and other small details including phone authentication, photo upload, range sliders, etc.
Explanation Flow
I also designed and shipped legday.nyc, the company's public marketing site, end-to-end in Next.js. The page opens with an animated mesh-gradient hero and a scroll-driven sequence of story sections that mirror the app's actual interactions — an auto-toggling visibility switch, a Rolodex-style mutual-match animation, scrollytelling around location and serendipity — and closes with a waitlist form that captures Instagram and TikTok referrals so the team knows where signups are coming from. The goal was to make the website feel like a continuation of the app, not a separate marketing artifact.
As one of two engineers, I shipped ~100+ changes across the app and site, helping take Leg Day from prototype to a live iOS app with real members checking in at real gyms. The work spanned visual identity, motion design, frontend architecture, and the minor details that connect them.
