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 β€’ 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. β€’ 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. β€’ Anti-poaching by design Subbing your class isn't an audition. After every cover, the substitute gets a one-tap reminder. Subbing stays subbing. β€’ 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. β€’ SOS escalation Out of time? Hit SOS. Every eligible instructor gets a priority alert immediately, bypassing head-start windows. β€’ Pass silently Not your class this time? Pass without notifying the poster. No social weight. Reversible. WHO IT'S FOR β€’ Yoga, pilates, and barre instructors juggling 2 to 5 studios β€’ Group fitness teachers who cover for each other on weekly rotations β€’ Studio owners who want their team to coordinate coverage without DMing them constantly β€’ Career substitutes building a roster across multiple studios WHO IT'S NOT FOR β€’ Anyone looking for a public sub marketplace. ClassSub is closed circles only. β€’ K-12 substitute teaching. β€’ Solo gym workouts. This is for class-format coverage. PRIVACY Your data lives in your trusted groups.
