QRServ
dev.uint.qrserv
Zapstore _@zapstore.dev Republished from GitHub / F-Droid by the Zapstore main account.
QRServ takes any selected files on your device and makes them available through its own HTTP server at an unused port number. The selected files can then be downloaded via web browser on another device and/or software that allows file downloads over HTTP from QR codes. Devices involved would need to be on the same network (i.e. access point, tethering [no mobile data required], VPN [with a supported configuration]). - QR Code -- Tap to show the URL in a tooltip -- Press and hold to copy the URL to the clipboard - Share sheet -- Share the download URL via the system share sheet -- Import files via the system share sheet from other apps -- Sharing text with the app creates a text file to share - Shows live import progress, whether for a single file or multiple - Multi-file selection -- Bundled into a ZIP archive -- Press and hold the archive's filename to see the originally selected files in a tooltip - Direct Access Mode -- serves the file directly from storage instead of copying it into app cache first, ideal for large files -- Single file selection only -- To use this feature on Android 11 or later, use the GitHub version (link is in-app under the 'about' dialog and later on in the description) -- please note that the Play Store version needs to be uninstalled first as it would be signed using a different certificate -- Toggle-able in settings - Detects if the selected file is removed while being served, or modified (Direct Access Mode only) - Show or hide the filename in the download URL - Notifies when a client requests or finishes downloading the file, including their IP address - Resumes interrupted downloads in supported software - Choose which network interface's IP address to serve from -- the server only listens there unless set to listen on all interfaces - Switches to another IP address if the selected one disappears, and suggests better ones as they appear - Private hotspot (Android 13 or later) -- shares over a Wi-Fi network the app creates, reachable only by devices you let join -- Scan a Wi-Fi QR code to join, or enter the network name and password by hand -- Switch an ongoing share to or from the private hotspot without selecting the file again -- Chooses 5 GHz for faster transfers on Android 16 or later (not all devices support 5 GHz or choosing the band) - Keeps sharing while the app is in the background, with a notification to stop sharing - Stops sharing when idle (10 minutes by default, adjustable) - HTTP server binds to a random free port by default, or a user-configured one - In-app theme selection - Supports various languages: English, French, German, Hungarian, Italian, Polish, Portuguese, Spanish, Russian, Turkish, Persian, Hebrew Permission usage: - android.permission.INTERNET -- Collection of available network interfaces and port binding for the HTTP server - android.permission.READ_EXTERNAL_STORAGE -- Read-only access to emulated, physical SD card(s) and USB mass storage - android.permission.FOREGROUND_SERVICE and android.permission.FOREGROUND_SERVICE_CONNECTED_DEVICE -- Keeping the HTTP server (and private hotspot) running while the app is in the background - android.permission.POST_NOTIFICATIONS -- The ongoing notification shown while a file is being shared, with the option to stop sharing - android.permission.WAKE_LOCK -- Keeping the device awake while a download is in progress, so it isn't stalled by the screen turning off - android.permission.CHANGE_WIFI_STATE -- Creating and stopping the private hotspot - android.permission.NEARBY_WIFI_DEVICES -- Creating the private hotspot (Android 13 or later). Not used to find or locate devices - android.permission.ACCESS_WIFI_STATE -- Checking whether the device can host a hotspot while staying connected to Wi-Fi - android.permission.ACCESS_NETWORK_STATE -- Noticing when the device's IP addresses change while sharing, so the QR code can follow QRServ is open source. https://github.com/uintdev/qrserv

- Android builds are now ARM64-only - Loopback IP addresses now listed - Aug 16, 2025 2.7.6- Updated dependencies - Updated framework Note: the next release will increase the minimum Android version to 7 (SDK version 24) due to it being an enforced minimum SDK version starting from Flutter 3.35.0. This version will still be available on GitHub, should you need to use it on a version of Android from 2014 or 2015. Another note: it was discovered that from v2.7.1, the version code prefix was added back in. As of v2.7.6, the prefix was removed again but that means updates via package manager will be prevented due to being deemed as a downgrade. If it fails to update, uninstall the application and then install the latest version.
