UI/UX Designer for Mobile Running App

We are looking for a talented UI/UX designer to create high-fidelity mockups for a mobile running app called Trackko. Trcakko gamifies running by letting users capture virtual territory on a city map — the more you run, the more of your neighborhood you own. Think Strava meets Pokémon GO. We have a clear concept, a defined color palette, and detailed screen descriptions ready to go. Your job is to turn this into beautiful, polished mockups that we can use to brief our development team. What the app does: Users go for a run with their phone in their pocket. The app tracks their GPS route automatically and shows them — after their run — which territory they have captured on a map of their city. Other runners in the same area compete for the same tiles. The app features gamification elements like XP, streaks, badges, leaderboards, daily challenges and team competitions. What we need: We need high-fidelity mockups for the following 4 screens: Territory Map screen — the main screen showing a dark city map with colored territory tiles belonging to different users Leaderboard screen — city ranking with podium, weekly stats and neighborhood king status Post-Run screen — summary after completing a run, showing captured tiles, XP earned and share option Home screen — daily quests, challenge cards, friend activity feed and territory summary We will provide: Full written descriptions of every screen with exact content, labels and layout Complete color palette with hex codes Typography direction Reference mockups (low-fidelity versions already created) Brand name and tone of voice
