Every Castle release with changelog and direct APK download. Latest is v2.1.0 (March 2026, 54.2 MB) — older versions kept available for devices that need them.

Latest mobile and TV APK builds collected with version notes and update guidance.
For most users — install the latest version, v2.1.0. It has the largest content library access, the latest streaming infrastructure for Indian users, and the most recent security patches. Every Castle release is built on the foundation of the previous one, so the newest version is always the most stable and feature-complete.
Older versions are kept available for two specific situations:
| Version | Released | Size | |
|---|---|---|---|
| v2.1.0Latest | March 2026 | 54.2 MB | View → |
| v2.0.8 | January 2026 | 63.8 MB | View → |
| v2.0.7 | November 2025 | 62.5 MB | View → |
| v2.0.5 | September 2025 | 61.2 MB | View → |
| v2.0.0 | May 2025 | 58.6 MB | View → |
| v1.x | 2024 series | ~50 MB | View → |
| Castle TVv1.1.2 | March 2026 | 20 MB | View → |
The v1.x series covered Castle's first-generation Android client throughout 2024. These versions used a different player engine, smaller content library indexing, and an older UI framework that has since been completely rebuilt for v2.0.0+. Most of the streaming infrastructure these versions relied on has been retired, so v1.x builds may have limited functionality on the current backend.
v1.x APKs are kept available primarily for historical reference. For functional use, install v2.0.5 or later.
The Castle Android TV build is a separate APK from the mobile version, with its own version numbering. Castle TV is a smaller and tighter codebase (currently 20 MB) optimised for d-pad navigation and big-screen layouts.
The v1.0 release was Castle's first dedicated Android TV build, separated from the mobile codebase to address the specific needs of d-pad navigation and 10-foot interface design. The v1.0.x series included multiple small iterations adding compatibility fixes for different Smart TV brands. v1.1.0 and later are recommended for current use.
Updating from any older version of Castle to the latest is straightforward — the new APK installs over the existing one without losing your data.
