Question 1

Do I need an account?

Accepted Answer

No. Sign in to your Plex, Jellyfin, Navidrome, Subsonic, or Emby instance. Credentials live on the device. Kontrole has no account system.

Question 2

Is it free?

Accepted Answer

Free during the open beta. After 1.0, Kontrole becomes a one-time purchase. Pay once, own the app, no subscription.

Question 3

Can I see the source?

Accepted Answer

Source is not public and we are not planning to open it. Instead, the roadmap, changelog, and feature requests live on this site.

Question 4

Does it phone home?

Accepted Answer

No user analytics. No listening history. No ad SDKs. No third-party trackers. Kontrole bundles Firebase Crashlytics, Firebase Performance, and Remote Config for crash reports, performance traces, and feature flags. Crash-reporting opt-out is planned before 1.0.

Question 5

Does it support DSD, ReplayGain, or bit-perfect output?

Accepted Answer

Not today. FLAC, ALAC, AIFF, MP3, and Opus play through the OS audio engines. DSD files are recognized in the library but not yet decoded. ReplayGain, bit-perfect output, and USB DAC exclusive mode are on the roadmap.

Question 6

Is gapless supported?

Accepted Answer

Partially. Tracks queue continuously through a prefetched concatenated player, which delivers gap-free transitions on most common formats. Engine-level gapless guarantees across every codec are on the roadmap.

Question 7

Does it support AirPlay or Chromecast?

Accepted Answer

Not in the beta. Full session casting is on the roadmap. Bluetooth output works on both platforms.

Question 8

Why Flutter?

Accepted Answer

One codebase across iOS and Android, identical behavior on each. Playback runs on the native audio engine per OS. A solo team can keep platforms in lockstep that way.

Question 9

Does it transcode?

Accepted Answer

Direct stream when your server can serve the file as-is. Server-side transcoding follows whatever your server is configured to do.

Question 10

How does Offline Mode work?

Accepted Answer

Pin an album or playlist to the device. Files download into the app, manageable from settings. Listening continues without your server.

Question 11

Will the beta die?

Accepted Answer

Active development. The roadmap on this site shows what is shipping, what is planned, and what has been shelved. Email the maintainer if something breaks.

Question 12

Where do I report bugs or request features?

Accepted Answer

Email the maintainer. A feature-request flow on this site is planned. Beta builds ship through TestFlight (iOS) and Play Internal (Android).
