YAACC is for people who keep music, photos or video on one device and want to play them on another screen in the same network, such as a DLNA-capable TV or speaker. It is a UPnP/DLNA app for Android that can act as a client, a server, a renderer and a controller. This page covers version 5.4.0, a 9.9 MB package with the ID de.yaacc. The unmodified APK is stored on TopDown APK, and a SHA-256 checksum is given so you can verify the file.
Free, no ads and GPL-3.0 licensed
YAACC is free and carries no ads. It has no in-app purchases.
The code is open source under the GPL-3.0-only licence and is published at github.com/tobexyz/yaacc-code. The developer website is yaacc.de.
Four UPnP roles in one app
The server role shares files from your device across the network. The client role does the reverse: it plays media from a media server on your device. As a media renderer, YAACC receives streams sent from other devices, and as a controller it directs renderers elsewhere in the network.
The store description adds more detail. You can control several renderers at once, and the receiver tab has play, pause and stop buttons. Files can be downloaded from a media server to the device, and URLs shared with the app can be sent to the current renderers.
Live streaming, SD cards and lock screen controls
On Android 10 and later, live streaming sends system audio and the screen to network devices. That requirement matters, since the app itself runs from Android 8.1.
Storage access goes through SAF, so you can browse and share files from external storage, USB drives and SD cards. Hardware volume buttons and media controls also work from the lock screen. Battery use is handled with a smart WiFi lock and foreground service management, and a shutdown timer is built in.
Maintenance record since 2013
The first release dates to August 16, 2013, and the most recent update was on October 27, 2026. That is a long run for a small network utility.
