The fitness app for people whose calendars actually run their lives. FitBetween reads your Apple Calendar, finds the openings between your meetings, and generates AI workouts sized to fit those exact gaps. No gym. No equipment. No 90-minute commitment. Just movement that fits the time you actually have. HOW IT WORKS - Connect your Apple/ Google Calendar (read-only, stays on your device) - See your day as openings - 15 minutes here, 45 there - Tap one. Pick a duration. Pick your space. Get an AI-generated workout instantly - Move. Track your streak. Repeat tomorrow. BUILT FOR PEOPLE WHO DON'T HAVE TIME This was built for the founder, the parent, the working person whose Sundays show "12 hours of social media use" and whose calendar shows three free hours they didn't notice. The lie isn't that you're too busy. The lie is that exercise has to be a separate thing you carve out time for. It doesn't. WHAT MAKES IT DIFFERENT - Reads your real calendar — not a generic "schedule a workout" reminder - AI workouts that actually fit your time, not generic 30-min sessions - Three space modes (Small, Medium, Open) so the workout matches where you are - Reminders 5 minutes before each opening - Streak tracking with a 24-hour grace window for the inevitable bad days - Privacy first: calendar data never leaves your phone NOT YOUR USUAL FITNESS APP No social feed. No leaderboard. No body comparisons. No subscription. No ads. Just you, your calendar, and the time you didn't know you had. Made by an indie developer who got tired of fitness apps that didn't fit a real life. -Deston, founder Questions or feedback: hello@fitbetween.app
