About

Ida OS

Features
Read full description

Ida OS is the studio operating system for independent dance studios. It replaces the e-transfers, WhatsApp threads, and emailed PDFs with one branded system for running your school. FAMILY PORTAL Parents log in to pay tuition, manage their card, check the live schedule, and find documents themselves — instead of texting you. TUITION & INVOICES Tuition collects itself every month through Stripe. Families on negotiated plans get custom invoices without a separate tool. LIVE CALENDAR Classes, workshops, rentals, and private blocks in one place. Change a class once and every family sees it instantly. ATTENDANCE Take the roll in one tap and track a rate per dancer, so a quiet absence shows up before the next competition. WORKSHOPS & COMPETITIONS Camps and intensives go from idea to paid signups in an afternoon. Competition entries, documents, and fees are centralized per event. ASK IDA Upload tournament packets, FAQs, and training videos once. Ida, your studio's built-in AI, answers parents' questions from them — day or night. MADE YOUR OWN Your logo, your colors, and a login screen you design. Families see your studio's brand, not generic software. Built inside a World Championship dance academy — not a software lab.
