How many are in the A1 morning group, who still owes an instalment, who hasn't come for two weeks? Çetele keeps your students as members and monthly fees as packages; it tracks the register, classes left and payments.
Members, packages and sessions are free to record, with no ads. The till and reports are free for your first 40 records; after that it's Çetele Pro, monthly or yearly, priced on the App Store.
