Editor's Overview

PlainApp: Phone Web Portal is a cast application developed by SmartCoding, packaged as a single Android APK of version 3.3 weighing in at 37.35 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 37.35 MB, so it installs quickly even on modest connections.
This build is signed by "SmartCoding" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

**PlainApp** is a free, open-source Android app that turns your phone into a self-hosted management hub accessible from any web browser on the same network - no accounts, no cloud, no subscriptions.

**Why PlainApp?**

Most phone-management tools route your data through their own servers, lock features behind subscriptions, or show ads. PlainApp is different:

- **100% local** - your data never leaves your network
- **End-to-end encrypted** - every connection is secured with TLS + XChaCha20-Poly1305
- **Free and ad-free** - no purchases, no upsells, ever
- **Fully open-source** - audit the code, build your own binary, or contribute

**Features**

**Web-Based Phone Management**
Open a browser on any device connected to the same Wi-Fi network to manage your Android phone - no app installation required on the computer side.

- **Files** - Browse internal storage, SD card, and USB drives; upload, download, rename, delete
- **Media** - View and manage photos, videos, and audio; stream them in the browser
- **Contacts** - View, search, and manage contacts
- **SMS & Calls** - Read messages and call logs; send SMS from your desktop
- **Apps** - List installed apps and export APKs
- **Notifications** - Mirror phone notifications to the browser in real time
- **Screen Mirror** - Live-stream the phone screen to the browser with audio and remote control support
- **Device Info** - Check battery, storage, network, and system details

**Built-in Android Tools**
PlainApp is also a capable standalone app:

- **RSS Reader** - Follow your favorite websites with a distraction-free reader
- **Video & Audio Player** - Full-featured media player with playlist support
