About River Montessori
Welcome to the official mobile app of River Montessori Charter School in Petaluma, California.
This beautiful, customizable design features a clear layout of resources for RMCS parents, staff members, visitors, and any other members of the RMCS community.
You can use this app to...
• Get notified about important school updates

• Contact the school with the push of a button
• Access important RMCS websites, like Transparent Classroom
• Browse the latest RMCS social media and news
• Learn more about River Montessori Charter School

Your RMCS app is fully customizable by you: Rearrange your portals to easily access whichever features you use most. If you access group chats frequently, you can put those portals front and center. If you never check school social media, you can turn that portal off.
This app is built with cutting-edge technology and a modern, user-friendly design that's optimized based on millions of usage data points. As the technology continues to improve, you'll notice your app getting better and better over time.
If you have ideas, suggestions, questions, or feedback about anything in the app, you can easily submit them through your app's suggestion box (in the "Profile" screen). This feedback will always be taken into account to continue improving the RMCS app experience for everyone.
This app was created using Onespot, an app builder platform designed to make mobile app creation simple and accessible for any organization. With Onespot, River Montessori Charter School was able to design and launch a fully functional, customizable app without needing any technical expertise. Onespot empowers schools, businesses, and communities to build apps that enhance engagement and streamline communication.
