Sixty Strong is a 60-day challenge app designed for Christians seeking holistic personal growth. The program focuses on six life pillars: Physical Fitness, Scripture Reading, Healthy Diet, Daily Prayer, Building Relationships, and Accountability. Participants join teams for accountability and mutual encouragement as they pursue personal transformation through guided daily challenges.
Good Fight did all the branding, mobile app design, and flutter development. We also designed and developed the responsive marketing website in Framer.
Sixty Strong’s vision required a fully developed digital platform that was engaging, easy to navigate, and spiritually uplifting. They needed a mobile app that could deliver daily challenge reminders, track progress, and foster team accountability. Additionally, they needed a powerful marketing website to tell their story, inspire users, and drive app adoption.
Our design and development process was guided by user engagement, spiritual motivation, and community building:
1. Discovery & Research: Conducted user interviews with Christians involved in personal development programs to identify motivational triggers.
2. Experience Mapping: Designed interactive user flows, from onboarding and challenge tracking to team communication and completion milestones.
3. UI/UX Design: Focused on clear, motivating visuals inspired by faith-based design principles, emphasizing personal growth and encouragement.
4. App Development: Built the app using Flutter for fast, scalable cross-platform functionality on both iOS and Android.
5. Marketing Website Design: Crafted a visually compelling website emphasizing the program’s spiritual impact through stories, testimonials, and app previews.
The implementation of Sixty Strong focused on creating a seamless, motivating user experience that blends spiritual inspiration with habit tracking. We designed the mobile app with a clean, intuitive interface where users could track daily tasks across six life pillars, set personal goals, and celebrate progress. Key features like team-based accountability, personalized reminders, and progress milestones were integrated to boost engagement and spiritual growth.
Using Flutter, we developed the app for both iOS and Android, ensuring smooth cross-platform functionality. The marketing website complemented the app by highlighting the program’s mission through compelling visuals, feature breakdowns, and clear calls-to-action, driving downloads and community growth.
