Check it yourself

  • Google links on this page go only to play.google.com, groups.google.com and support.google.com. Look at the address bar before you sign in.
  • Once you are in the test, the Google Play page address ends in id=app.svan.
  • The privacy policy is public: Read it
  • The contact address and the GitHub account that hosts the privacy policy (iamhariize-maker) both belong to the developer.

Closed beta

Help Svan reach Google Play.

Before a new developer can publish on Google Play, Google requires a closed test: at least 12 testers who stay opted in for 14 days in a row. That is the only reason I am asking. Google's rule, on Google's own help page

You'll need

  • An Android phone with Android 10 or newer (64-bit).
  • A Google account. A spare one works just as well.
  • About 14 days with Svan installed.
  • Your music app. YouTube Music, Gaana and Apple Music work without setup. Amazon Music, JioSaavn and some others need an optional extra step (Shizuku).

  1. Join the tester group.

    It is a Google Group. Joining is how Google Play knows your account may test Svan.

    The group link opens soon.

    Check back on this page.

  2. Opt in on Google Play.

    Open the test page with the same Google account, tap Become a tester, then install Svan from Google Play.

    The Google Play test link opens soon.

    Check back on this page.

  3. Keep it for 14 days.

    Use it like any other app. Please stay opted in: Google only counts testers who stay 14 days in a row.

  4. Tell me what you find.

    Your phone model, your music app, what you did and what happened. A screenshot helps. Short is fine.

Inside

What you can tune.

  • Parametric and graphic EQ

    Drag bands on the curve, tap a value to type it exactly, undo, or switch to the graphic view.

  • Headphone profiles

    Search for your headphones or IEMs and load a correction curve from AutoEq measurement data, or import your own.

  • Presets

    Built-in presets. Import or paste AutoEq or APO text, save your own curves, and export or restore all your settings.

  • Svaresa

    An automatic EQ with its own manual workspace. Hold to compare.

  • Hi-Fi status

    Shows which playing app Svan can actually reach on your phone, so you are not guessing.

  • Optional audio engine

    Off by default. With Android's consent, it processes eligible playback on the phone.

Appearance

A complete world for listening.

Five themes. Your sound stays as you left it.

Also in the app: Prism Grove and Mint Circuit.

Compatibility

What works today.

No setup

YouTube Music, Gaana, Apple Music (Android).

Play a song and tune it. The developer has checked these on several phones.

Optional setup

Amazon Music, JioSaavn and some others.

These need Svan's optional enhanced detection, which uses Shizuku. It is an extra step, and only if you want it.

Not promised yet

Results depend on your phone, the music app and where the sound goes (speaker, wired or Bluetooth). Some apps and outputs do not allow effects. Bluetooth delay and screen-off behaviour are still being checked, and reports are welcome. The Hi-Fi screen shows what actually works on your phone.

Privacy

Every permission, explained.

Svan has no accounts and no developer server, so the developer holds no data about you from the app. Your audio is processed on your phone and never uploaded. The app goes online only to download headphone data from GitHub when you search for it. Read the full privacy policy

PermissionWhyWhen
Microphone Android requires it for any app that processes other apps' playback, which the optional engine does, and for the Lab's measurement tools. Svan does not intentionally record microphone input, and never saves or sends captured audio. Only if you turn on the optional engine or run a Lab measurement.
Notification and foreground service Shown while the optional engine runs, so you can see it and stop it. While the optional engine runs.
Display over other apps Only for the optional floating control. Off until you turn it on. Only if you turn on the floating control.
Internet Fetches headphone data (AutoEq) from GitHub when you search. GitHub sees ordinary network details, such as your IP address. When you search for headphone data.
Shizuku (optional) If you set it up, a read-only helper reads two fixed audio status reports to detect which music app is playing. It does not read other apps' data or content. The privacy policy describes the one optional extra step in full. Only if you set it up.
Not used No notification access, no accessibility service, no SMS. No ads or analytics SDK. Svan never touches calling, messaging, payment or voice-assistant apps. Never.

Questions people ask first.

Is this real? How can I check?

Most of this page you can check yourself. The Google links go only to play.google.com, groups.google.com and support.google.com, Svan's app ID on Google Play is app.svan once you are in the test, the privacy policy is public, and you can write to harizisclean@gmail.com. I will never ask you for an OTP, a password or money.

What do you get from my email?

When you join the tester group, I can see your Google account email address, and Google Play uses it to give you the test. I use it only to run this test and to reply to you. It goes on no mailing list and is shared with no one. You can use a spare Google account, and you can leave at any time.

Will Svan record my microphone or my music?

No. Android's microphone permission is required for processing playback. Captured playback is processed live and is never saved or uploaded. Svan does not intentionally record microphone input.

Do I have to pay?

You will never be asked to pay on this site, in the tester group or by email. Anything about pricing will be announced on this page first.

Why does Google need 12 testers?

New personal developer accounts must run a closed test with at least 12 testers for 14 days before publishing. Google's rule, on Google's own help page

Which phones and music apps work?

Android 10 or newer, 64-bit phones. YouTube Music, Gaana and Apple Music (Android) work without setup. Amazon Music, JioSaavn and some others need Svan's optional enhanced detection. Bluetooth delay and screen-off behaviour are still being checked, and reports are welcome.

Do I need Shizuku?

No. YouTube Music, Gaana and Apple Music work without it. It is only for detecting Amazon Music, JioSaavn and similar apps.

How do I leave the test?

Open the Google Play test page again, choose Leave the program, then uninstall. Leaving early lowers the tester count, so please tell me if you are going to.

Is Svan open source?

No. The code is private. The privacy policy describes what the app does with data.
