CrispSorter v0.4.0

Highlights

CrispSorter runs on Android. The full app — LanceDB, Tantivy, fastembed, OCR, PDF extraction, cloud-backup sync, batch sort — cross-compiles for aarch64-linux-android with 100% feature parity. No features removed, no thin-client compromises. Sort your Downloads folder on your phone the same way you sort documents on your desktop.

Mobile-first UI. A responsive bottom tab bar replaces the sidebar on phones (<768px). All core components (Stapel, Chat, Übersicht, Translate, Settings) adapt to touch-sized targets and stacked layouts. Tablets get an icon-only collapsed sidebar.

Android support

  • tauri android init generates the Gradle project under src-tauri/gen/android/
  • Full Rust workspace cross-compiles for aarch64-linux-android (arm64)
  • Vendored OpenSSL (openssl = { features = ["vendored"] }) — no system libssl needed
  • Patched lance-linalg for Android aarch64 NEON f16 kernels
  • Platform-scoped Tauri capabilities: default.json (desktop: shell + process) vs mobile.json (no shell/process, scoped filesystem)
  • CI: release-android job in release.yml — JDK 17, Android SDK/NDK 26.3, builds + uploads APK to GitHub release

desktop feature flag

Desktop-only code is now gated behind --features desktop:

Gated behind desktop Why
tauri-plugin-shell / tauri-plugin-process No subprocess spawning on Android/iOS
mistralrs (local LLM inference) Sidecar model — spawns llama-server
notify (folder watcher) No inotify on Android
Sidecar commands (llama.cpp, MLX, Ollama) OS-level process spawning
TTS module (tts/mod.rs) Spawns say/espeak/PowerShell

Desktop CI/release builds must add --features desktop. Mobile builds omit it. All batch sort, indexing, search, sync, and cloud LLM features work on both platforms without the flag.

Responsive UI

  • Phone (<768px): Sidebar hidden, bottom tab bar with 5 tabs (Stapel, Chat, Übersicht, Translate, Settings). safe-area-inset-bottom for iOS notch.
  • Tablet (768–1024px): Sidebar collapses to icon-only (64px).
  • Desktop (>1024px): Unchanged.
  • BatchReview: stacked layout on mobile (detail pane below table instead of beside), touch-sized buttons.
  • Settings: horizontal scrollable tab bar on phone instead of vertical sidebar.
  • Chat: sidebar hidden on phone, compact header.
  • IndexIngest / Translate: scrollable tabs, tighter padding.
