Appazur will provide you with a Progressive Web App for users who do not have an iOS or Android device, with text messages (SMS), email, and web browser pop-up notifications (web push). This works, for example, with ChromeOS (Chromebooks), Windows, and macOS.

However, a mobile-optimized website is not enough. Some ways an app can add value:

• Offline access to information (connect with parents and students on the move with wi-fi tablets, slow connections/out-of-range, etc.)
• Deep device integration (camera, social media sharing, calendar, reminders, etc.)

Redesigning an existing website for mobile can be a big project, so signing up for a customized school app from a specialized service provider like Appazur may be less expensive.
