Hosted by The AI Fellowship Europe, in partnership with Replit & Adapty. Are you ready to build high-performance mobile apps at the speed of thought? This June, The AI Fellowship Europe is teaming up with Replit and Adapty to host an intense, 48-hour online hackathon. Build a fully functional mobile application, integrate an elite subscription model, and present a live working demo — all in one weekend. 📅 Date: Friday, June 26 (18:00 CET) – Sunday, June 28, 2026 (18:00 CET) 📍 Venue: 100% Online 🇪🇺 Eligibility: Open exclusively to developers, designers, and builders based in Europe. 💡 The Challenge The paradigm of mobile development has shifted. With "Vibe Coding" on Replit, you focus on the product vision, user experience, and architecture, while AI handles the heavy lifting of code generation. But a great app needs a sustainable business model. That’s why you’ll be integrating Adapty, the leading in-app subscription and paywall infrastructure. Your mission is to build a high-quality mobile app (iOS or Android) from scratch over the weekend, implement a premium onboarding flow, and craft a conversion-focused subscription paywall using Adapty. 🎁 Exclusive Participant Perks • Replit Core Credits: All approved participants will receive $20 in Replit credits (promo codes valid for the hackathon duration) to run high-performance AI agents. • Elite Mentorship: Direct access to Developer Advocates and Engineers from Replit and Adapty on dedicated Discord channels to unblock your builds in real-time. • Global Network: Connect and team up with members of the 2,300+ global community. 🏆 Prizes & Glory • First Place: 400€ + Dedicated feature in all the partners networks. • Adapty Conversion Prize: 1,000€ ! Awarded to the most creative, high-converting, and visually stunning paywall design. • Replit Innovation Award: Awarded to the team that leverages speculative vibe-coding techniques most advancedly. 🚦 Mandatory Requirements & Judging Criteria Your submission will be graded on four pillars of equal weight (25% each): Apple & Android Frameworks (25%): Native performance, UI polish, and design-system quality. Monetization & Subscription (25%): Seamless Adapty SDK integration, reliable purchase flows. Onboarding & Paywall Design (25%): Value-proposition clarity and conversion psychology. Demo & Storytelling (25%): Quality of the pitch and live product demonstration. 🚀 Extra Points: • +15 Points: Releasing the app live on the App Store or Google Play by Sunday 18:00 CET. • +5 Points: Sharing your "build-in-public" development story on LinkedIn/X using #AIFellowship #VibeCoding #Adapty #Replit. 📝 How to Register Click "Request to join" and fill out the form.
