ClassKeep
Read full descriptionHide full description
Still tracking lessons with paper or spreadsheets—and dreading month-end reconciliation? ClassKeep is for teachers who run their own students— schedule, attendance, and lesson credits in one flow. After each class you’ll know: how many were used, how many remain, and whether the money adds up. 【Sound familiar?】 • A parent asks on Saturday “how many lessons left?”—you dig through chat history • Excel says “attended,” but payments don’t match • Reschedules and make-ups live in one place; balances live in another • School admin software is too heavy for one person 【Who it’s for】 • Home / studio one-on-one: piano, voice, guitar, violin, art, private speech therapy… • Small groups: beginner band, dance teams, coding clubs, kids’ chess, youth theater… • Sports & fitness: swim lessons, tennis coaching, personal training packages, martial arts… • Academic tutoring: SAT / ACT prep, math & reading, AP subjects, college essay coaching… • Mixed formats: private lessons on weekdays, 3–8 student groups on weekends, different rates by level • Not a huge roster—but the books must be clear: dozens of active students, parents asking “lessons left / how much paid” It’s a strong fit if— you find your own students, teach, and get paid yourself as an independent tutor, coach, or part-time teacher; you only need to take attendance on your phone before/after class; and you’d rather not pay for clunky school software or wrestle spreadsheets again. Not a fit for: franchise academies, multi-location studios with staffed front desks, multi-teacher teams, or anyone who needs a parent booking portal / admissions CRM—use a full studio management system instead. 【With ClassKeep】 Maya teaches piano from her home studio: she sets pricing for “Piano — Intermediate,” enrolls Emma and Noah for 16 lessons each, opens a Saturday trio class, and generates the month’s schedule in one go. On lesson day she marks attendance—present deducts a credit; excused absence does not. When parents ask at month-end, student profiles or Stats show the answer at a glance. Private lessons work the same: one student = one class, fixed weekly time, attendance deducts credits. Data stays on your device—backup and export anytime. 【Free & Pro】 The free plan covers the full teaching loop. Free tier has limits on students, active classes, and courses; upgrade to Pro for unlimited capacity as you grow. —— Features (skim when you need them) —— • Class schedule: day / week / month; reschedule this session only or all future ones • Attendance & credits: present / leave / absent; balances update live; over-attendance when credits run out • Lesson ledger: enroll, renew, withdraw—remaining lessons and amounts in one place • Conflict warnings when times collide • Local notifications: before class, when renewals are due, when a class is almost fully scheduled • On-device data: spreadsheet export + backup/restore—no cloud account required Subscriptions: Pro is an auto-renewable Apple subscription. Manage or cancel in Settings. See in-app subscription details.
