TonStromYour phone’s sound. On every speaker.
TonStrom sends whatever plays on your phone – music, podcast, video – to the speakers on your Wi-Fi: network speakers, AV receivers, TVs. To several at once and in sync, if you like.

The speaker is already there
Many devices at home can play music from the home network – just not what’s playing on your phone right now. TonStrom closes that gap.
Whatever plays on your phone
Music app, podcast, video or audiobook: TonStrom captures the sound as Android outputs it and streams it to the chosen speaker.
Find and pair speakers
TonStrom searches your Wi-Fi for suitable devices. Paired speakers are ready immediately next time.
Several rooms, one beat
In party mode several speakers play at once. You set the delay per speaker with a metronome test tone – and it is remembered.
No echo
The speaker plays a few seconds after the phone. So TonStrom can mute the phone while streaming and restores the volume when you stop.
The right format
Not every speaker understands every format. The test tone tells you whether it sounds clean – TonStrom remembers the working format per device.
Your own network only
Phone and speakers talk to each other directly. No cloud, no account, no detour through the internet.
At once. Everywhere.
Every speaker takes a different time to start playing. TonStrom evens that out: start the test tone, listen which speaker ticks early, and raise its delay until all ticks coincide.
- Pick any number of paired speakers
- Delay per speaker, stored permanently
- Also applies to normal streaming from the phone
- Volume per speaker right in the app
Good to know
When starting, Android asks whether TonStrom may “share your screen”. Please choose “Entire screen” – only the sound is used, never the picture. Some apps block capturing; then it stays silent.
No account, no cloud, no profile
TonStrom only connects to devices on your Wi-Fi. The sound goes straight from the phone to the speaker and is stored nowhere. All details
Microphone? No.
Android requires the “record audio” permission for capturing playback. TonStrom never uses the microphone.
No picture
From the screen share only the sound is used, never the picture.
No ads, no tracking
No analytics, no advertising, no crash reports.

FAQ
Which devices work?
Devices that accept music from other devices on the home network – often labelled “DLNA”: many AV receivers, network speakers and smart TVs. The test tone in the app shows whether a device plays the live stream cleanly.
The speaker isn’t found.
Phone and speaker must be on the same Wi-Fi and the speaker switched on. Some devices need “network standby” or network remote control enabled.
Why does the speaker play later than the phone?
The speaker buffers the stream so it doesn’t drop out during short Wi-Fi hiccups. That’s why you can mute the phone while streaming.
It stays silent although music is playing.
In Android’s sharing dialog, “Entire screen” must be selected – with “A single app” only silence arrives. Also, some apps, e.g. for protected films, don’t allow capturing.
