About

ClassSub

Features
Read full description

When you can't teach, someone you trust can. ClassSub is a sub-coverage app built for fitness instructors. It works for yoga, pilates, barre, group fitness, dance, and anything class-based. Post a sub request once. The trusted instructors in your group see it instantly. The first qualified person claims it. No public marketplace, no random instructors, no group-chat scramble at midnight. WHY CLASSSUB IS DIFFERENT • Trusted circle, not a marketplace Your sub requests only go to people you've explicitly added to your group. You build the circle once. The trust compounds. • Structured class handoff Door code, music, mat orientation, regulars with special needs, expected attendance, level. Every field built from real instructor research. Your sub walks in already knowing the room. • Anti-poaching by design Subbing your class isn't an audition. After every cover, the substitute gets a one-tap reminder. Subbing stays subbing. • Auto-calendar sync Claim a class. It lands in your system Calendar with reminders at 24h, 4h, 1h, and 30 minutes before. Even 20-year veterans miss classes when they're not on the calendar. • SOS escalation Out of time? Hit SOS. Every eligible instructor gets a priority alert immediately, bypassing head-start windows. • Pass silently Not your class this time? Pass without notifying the poster. No social weight. Reversible. WHO IT'S FOR • Yoga, pilates, and barre instructors juggling 2 to 5 studios • Group fitness teachers who cover for each other on weekly rotations • Studio owners who want their team to coordinate coverage without DMing them constantly • Career substitutes building a roster across multiple studios WHO IT'S NOT FOR • Anyone looking for a public sub marketplace. ClassSub is closed circles only. • K-12 substitute teaching. • Solo gym workouts. This is for class-format coverage. PRIVACY Your data lives in your trusted groups. We don't run ads, don't sell data, and don't share your activity with anyone outside the groups you're in. Full privacy policy: classsub.inpulsd.com/privacy QUESTIONS? hello@inpulsd.com
