Simpleclass is an online classroom platform built for tutors, small schools, and education providers who rely on breakout rooms and live interaction.
Unlike generic video conferencing tools, Simpleclass focuses on structured online classes rather than meetings. Teachers can manage multiple breakout rooms at once, monitor student activity, and move between groups without losing visibility or control. This makes it especially suitable for tutoring centers, homework support organizations, and language schools running parallel group sessions.
The platform includes institution-based access, role separation (teachers and students), and a clear classroom flow designed for recurring lessons rather than one-off calls. Simpleclass is designed to be simple to use for both educators and students, without the complexity of enterprise meeting software.
Simpleclass is fully web-based and requires no downloads. It is hosted in Europe and built with GDPR compliance in mind, making it suitable for European educational organizations that need predictable data handling and privacy guarantees.
The product is independently built and bootstrapped, with a focus on reliability, clarity, and practical classroom needs rather than marketing features. Simpleclass aims to provide a focused alternative to general-purpose video tools for organizations that teach online every day.
Use variables, functions, and units and see results immediately. Add comments, copy calculations to apps like Word or Excel, or share them through an editable link. Calculate thermodynamic fluid properties with the integrated CoolProp library.
