Inspiration
Coaching is one of the highest ROI investments you can make, but most people never access it. They don't know how to find the right coach, don't have the time, or can't afford it and the same been experienced by Simon. We wanted to bring personalized coaching to everyone's pocket, making guidance accessible at the moment you need it most. Inspired by Simon's vision at BetterCreating, we set out to demystify AI agents and create something people can just open and start using, no complex setup needed.
What it does
Muse Coach is a minimalist AI coaching app with 5 specialized coaches:
Marcus (Stoic) : Uses ancient Stoic frameworks for decision-making and resilience
Aria (Productivity) : Applies Essentialism and time-blocking methods
Luna (Creative) : Draws from The Artist's Way for unlocking creativity
Sage (Wellness): Uses RAIN technique for emotional awareness
Atlas (Career): Helps with SMART goals and professional growth
How we built it
React Native + Expo (SDK 54) for cross-platform mobile development OpenAI ** GPT-4o-mini** for AI coaching responses
RevenueCat for subscription management (Free tier: 15 msgs/day, Pro: unlimited) Zustand + AsyncStorage for persistent state management
Apple Sign-In for authentication
React Navigation 7 for smooth screen transitions
Haptic feedback throughout for a premium feel
Challenges we ran into
AI response formatting : Getting coaches to sound human (not robotic) took iteration on prompts, including explicit instructions to avoid em dashes and professional jargon. -Also solved this by using React Native's built-in Animated API instead.
Accomplishments that we're proud of
Zero-friction onboarding: From install to first conversation in under 30 seconds
Meaningful AI interactions: Coaches use real frameworks (Stoic decision trees, RAIN technique, Essentialism) rather than generic chatbot responses
Auto-generated wisdom:Every conversation automatically produces saved insights
Beautiful minimal design: Warm color palette, SF Pro typography, smooth animations
Full subscription flow: Working paywall, restore purchases, cross-device sync via Apple ID
What we learned
Subscription apps need to handle edge cases: restore purchases, anonymous users, trial period and also prompt engineering is an art
What's next for Muse Coach by Kalyan
Cloud sync: Backup conversations to the cloud so they persist across devices
Session summaries: AI-generated digests after each conversation
Reminders: Push notifications to check in with your coach
Progress tracking: Visualize growth over time with insights dashboard
