What is a PWA?

A Progressive Web App is a web-built application that delivers a native app experience. Instead of downloading it from a traditional app store, you install it directly through your web browser (Chrome, Safari, or Firefox) onto your Android, iOS, or Windows home screen or dock.

How does JSON database file sharing work?

Because Mithreal apps are local-first, 100% of your data is saved securely within your device’s browser storage. To back up your data or sync it across multiple devices, you simply use the built-in export tool to generate a standard JSON database file, then import that file into the app on your other device.

What platforms and browsers are supported?

Our tools are fully tested across Android, iOS, and Windows ecosystems. They are optimized to run seamlessly inside any modern browser engine, including Chrome, Safari, and Firefox, and function beautifully as standalone desktop or mobile apps once downloaded.

Is there a monthly fee?

No. Mithreal apps operate on a straightforward, one-time fee model with zero hidden monthly subscriptions. Because the lightweight architecture runs locally on your hardware rather than consuming heavy server infrastructure, we pass those structural savings directly back to you.
