ECHO Developer Program

The ECHO Developer Program currently recruits contributors for Android and Apple mobile development (iPhone and iPad), including mobile UI, playback, cross-device connectivity, mobile audio, and device testing.

This program participates in Android and Apple mobile development only. It does not participate in or recruit for PC development. “Apple” here means the iPhone and iPad clients, not the macOS desktop client.

Approved developers may receive ECHO Pro for development and testing, join the developer chat, and get access to developer repositories or collaboration materials when needed.

Official ECHO development is only for approved ECHO Developers. People who are not approved through the Developer Program may report issues, suggest improvements, maintain their own forks, or send documentation corrections, but they may not participate in official ECHO development, access developer repositories, use internal materials, or submit implementation work that expects to be merged.

Approved developers receive access only to the Android or Apple mobile scope required for their work. Approval does not grant access to PC repositories or PC development.

Before contributing mobile code, builds, releases, connectivity work, or engineering documentation, read the Developer Access Rules.

When applying, include:

  • QQ, for identity confirmation and group invitation.
  • GitHub profile, public projects, or contribution history.
  • Android or Apple mobile development experience, including your stack, released apps, public projects, or real-device work.
  • The platform you want to work on: Android, Apple mobile, or both.
  • The mobile direction you want to contribute to.
  • Optional competitive-programming or portfolio links, such as Codeforces, AtCoder, Luogu, or other public work.

Playback-app authors and professional recording or audio workers may apply directly with a short description of their background.

PC frontend, Electron, Windows or macOS desktop integration, ASIO, WASAPI, and other PC-only development are outside the current program scope.

Developer access and Pro eligibility are for development and validation. Do not share authorization, internal repositories, test builds, or unreleased information. Contributions should stay scoped, stable, verifiable, and aligned with ECHO’s long-term maintenance.
