While Project Arrhythmia (recently rebranded as Afterbeat [1.11]) is not currently available as a native, free standalone app on the Google Play Store, it is officially planned for a future mobile release. Official Mobile Status
The developer, Vitamin Games, has confirmed that a mobile port is "actively being worked on".
Availability: It is currently only officially released on PC (Steam) in Early Access.
Features: The mobile version may not include every feature of the PC version, but the developer aims to include as much of the core "musical bullet-hell" experience as possible, potentially including cross-platform custom levels.
Partnership: Vitamin Games recently partnered with publisher Kwalee to bring the game toward a full 1.0 release in 2026, which may accelerate cross-platform availability. Free Demos & Fan Projects

Fan-made Content: Projects like the Project Arrhythmia- Universal Hole Collection on Game Jolt are community-driven expansions, though typically for PC.
Emulation: Some users attempt to run the PC version on Android using Windows emulators like Winlator, though this requires owning the game on PC and having a high-end mobile device. Similar Free Rhythm Games on Android

Important Note: Project Arrhythmia is a paid rhythm game on Steam (typically $4.99–$9.99) developed by Vitamin Games. There is no official free version of the full game on the Google Play Store. Any APK claiming to offer "Project Arrhythmia for free" outside of the official Steam or Itch.io pages is likely:
- A pirated/cracked copy (which is illegal and may contain malware).
- An outdated, unofficial, or fake app.
- A demo or fan project (not the real game).
If you want to play legally for free, the developer has occasionally released demos or participated in game jams. The best free, legal alternative is to play community levels via the Steam version (which requires purchase) or try other free rhythm games like osu! or ADOFAI demos.
Project Arrhythmia — Android (Free)
Project Arrhythmia is a rhythm-based action game known for its minimalist visuals, intense soundtrack, and precision gameplay. The Android free version offers an accessible way to experience its core mechanics on mobile devices.
The Verdict: Is there a legal "Free" way?
Yes, but not on Android. The developer occasionally gives away Steam keys during game jams or on the official Discord. Also, the PC demo (free on Steam) includes 5 official levels.
For Android: The most interesting "legal free" alternative is "Rotaeno" (free demo) or "Orzmic" (completely free, no ads, similar geometric style). Many Project Arrhythmia level creators have ported their custom levels to Orzmic because it officially supports mobile. If you want to play legally for free,
3. Timing, Latency, and Synchronization
Problems to solve:
- Audio callback jitter and main-thread stalls cause desync.
- Varying device audio latency and buffering.
Solutions:
- Use low-latency audio APIs (AAudio/Oboe) with small buffer sizes; process input and timing in the audio callback where feasible.
- Predictive rendering: schedule visual events slightly ahead to match audio playback time.
- Implement a calibration tool: play click track and measure user tap offset to compute a global input offset.
- Use constant audio clock as authoritative source — derive game timestamps from audio frames processed.
Example calibration flow:
- Play metronome at known BPM in a loop.
- User taps to clicks; app computes mean offset.
- Apply offset to input handling and note hit windows.
Example stack
- Native core: C++ (game logic, audio via Oboe/AAudio, timing).
- Rendering: OpenGL ES 3.1 with GLSL shaders; optional Vulkan path.
- App shell: Kotlin/Java for UI, settings, permissions, downloads.
- Build: Gradle + CMake, ABI splits for size.
- Packaging: Android App Bundle with dynamic feature modules for extra level packs.
What is Project Arrhythmia?
Before diving into the Android version, let’s recap why this game is so beloved. Developed by First Second Gaming, Project Arrhythmia is a rhythm-action game where instead of tapping static notes, you pilot a small geometric ship (a cube, triangle, or custom shape) through a barrage of obstacles that move exactly to the beat of the music.
Unlike Osu! or Cytus, this game emphasizes survival and movement. Each level is a choreographed “light show” of bullets, spinning lasers, and expanding rings. The game’s biggest strength is its Level Editor and Steam Workshop support, allowing players to create and share their own rhythm maps for any song.
8. Security, Privacy, and Permissions
Minimal required permissions:
- Storage (optional) for importing levels — use SAF (Storage Access Framework) instead of broad READ_EXTERNAL_STORAGE.
- Internet (optional) for downloading levels and updates; allow offline play.
Privacy design:
- No analytics by default; opt-in telemetry only. If community-built, document exactly what is collected.
