Piano, swimming, dance, tutoring — the more activities you sign up for, the harder it gets to answer three simple questions: What's next? How many lessons are left? How much have I paid? ClassLog answers all three: · Today's classes at a glance — tap once to check in, hours deduct automatically · See how many lessons remain for each class, with a low-balance reminder · Every payment logged against the right course — refunds and receipts included Multiple kids? Keep them separate, view them together. Get a simple breakdown of attendance and spending per child. Your data stays on your device — nothing is uploaded. CSV import and export included, so nothing is lost when you switch phones. Track every class for your kids.
