Frequently asked questions

The app on every device that should play along and one Wi-Fi network for all of them. You don't need an account. Allsono runs on Macs with macOS 14.2 or later, Android phones with Android 10 or later and iPhones with iOS 17 or later.

No. Allsono works without an account, and devices on the same Wi-Fi network simply play together, with or without one. If you sign in (in the app's settings), Allsono keeps your language, appearance and fine-tune on your account, so they come back on a new device or after a reinstall.

Nothing. Allsono is free, on all your devices, and you don't need an account for it.

No. The sound travels over your own Wi-Fi network, never over the internet. You only need internet to sign in, which is optional.

On a Mac the app tells you about a new version and installs it itself. On Android updates come through Google Play, on the iPhone through the App Store or TestFlight.

A Mac: it shares the sound of all your apps and plays along exactly in time itself. An Android phone also plays along exactly in time, but some apps, such as Spotify, don't share their sound there. An iPhone as the source runs slightly ahead of the speakers itself.

Yes, with a Mac as the source: Spotify, YouTube, podcasts and other apps all share their sound. On Android, Spotify doesn't let other apps capture its sound; Allsono then tells you and keeps the sound on the phone itself. Send Spotify to your Mac with Spotify Connect instead and make the Mac the source. YouTube, YouTube Music and most other apps do work on Android. On iPhone, Apple Music can't be shared.

Yes, with one limit set by Apple: iOS doesn't let any app delay or mute the sound of other apps. All speakers then play perfectly in sync, but the iPhone itself runs slightly ahead. Have a Mac? Then make the Mac the source: everything plays perfectly in sync. With Spotify Connect or AirPlay you can still control the music on the Mac from your iPhone. Without a Mac, turn the iPhone itself down.

Android only passes on other apps' sound through that permission. Allsono only uses the sound, never the picture, and the sound only travels over your own Wi-Fi to your own devices.

All speakers play the same fragment at the same moment, within a few milliseconds on a good Wi-Fi network. Only an iPhone that is itself the source runs slightly ahead (see above). Allsono also measures and compensates for the delay of Bluetooth speakers.

All speakers wait a moment so they can play exactly together: normally about 0.2 seconds. If your Wi-Fi stalls, that buffer grows by itself, up to 1.5 seconds, and after about a minute of calm it comes back down. With music you won't notice; with video the sound runs behind the picture because of it.

It's usually the Wi-Fi network. Allsono then enlarges its buffer by itself; in the first half minute you may still hear a hiccup or two, after that it settles. If that doesn't help, move the devices closer to the router or use 5 GHz. If a Mac with a Bluetooth speaker stutters, see the question about that below.

Open "Fine-tune" for that device, on the device itself or from the source. If it runs ahead, choose +; if it runs behind, choose −. Often it's a Bluetooth speaker that doesn't report its own delay accurately.

Yes. Connect the speaker to a device that plays along as a speaker; Allsono measures the speaker's delay and accounts for it. Don't connect it to an Android phone that is the source: most Bluetooth speakers stay silent there.

As the source, Allsono sets the phone's media volume to 0 so you don't hear the unsynced original. Most Bluetooth speakers use that media volume as their own volume, so they go to 0 as well. Allsono then shows a notice. Connect the speaker to another device running Allsono and add that as a speaker; then it plays along in sync.

AirDrop, AirPlay and Handoff make a Mac's Wi-Fi jump to another channel very briefly now and then. Together with a Bluetooth speaker, the Wi-Fi can then drop out for a second. Allsono notices and shows a notice. Set AirDrop to No One and turn off AirPlay Receiver and Handoff (System Settings › General › AirDrop & Handoff), play through the Mac's speakers, or connect the speaker to a phone instead.

No. Allsono plays on Macs, Android phones and iPhones, and on the speakers and headphones connected to them. AirPlay speakers and TVs aren't part of that: Allsono can't control their timing, so they wouldn't stay in time with the rest.

No. The sound only travels over your own Wi-Fi, straight from the source to your other devices. If you are signed in, our server only sees your account, which devices are signed in and their settings.
