Unified API for runtime permission management and device information, offering asynchronous, coroutine-friendly permission requests/status (single or batch), rationale handling, and location monitoring with live-tracking and state updates.

Redux-style state management with modern toolkit features: type-safe reducer DSL, reactive StateFlow, memoized selectors, async thunks, entity adapter, listener middleware, slice pattern.

High-level API for discovering, connecting to and exchanging messages with Bluetooth mesh companion devices, featuring scanning with filters, reliable acknowledgements, auto-sync time, channel polling and message streams.

Ergonomic toolkit for app architecture: state machines for view/scene orchestration, storage abstractions with persisted delegates, recycler utilities, foldable posture helpers and a lightweight context provider.

Rust-backed, high-performance WebTransport wrapper offering an idiomatic async API for establishing connections, managing uni/bi-directional streams and unreliable datagrams, plus TLS certificate handling.

Adds concurrent mapAsync, pairwise emissions, flow racing, exponential-backoff retries, timeout-or-null, and default/fallback helpers for building composable, resilient asynchronous streams with concise APIs.

In-app developer toolbox offering network inspection, log viewing, crash reporting, leak detection, device diagnostics and performance monitoring with zero configuration, in-memory storage, dark themes, cURL/PDF export.

Finite-state machine DSL for explicit state graphs with exhaustive state types, event payloads for constructing states, observable reactive state stream, deterministic non-reentrant dispatch, and Mermaid export.

Enables real-time bidirectional communication with Phoenix Channels via WebSocket, channel join/leave, push messages, event routing, automatic exponential-backoff reconnection, heartbeat, and type-safe message handling.

Restores lifecycle-agnostic navigation and hierarchical scope management for Compose UIs: visibility-aware lifecycles, type-safe navigation, DI-agnostic dependency scoping, and ref-counted coroutine scopes.

NFC toolkit for tag reading/writing: NDEF read/write, raw APDU transceive, capability introspection, plus test doubles with error injection and delay simulation.

Pure domain layer enforcing Clean Architecture with typed contracts, DomainResult error handling, composable validators and policies, deterministic testing via injected clock and id providers, no framework dependencies.

Event and result observation with DataResult, LiveData/Flow wrappers, chaining/mapping/merge helpers and a Compose-first DSL for declarative loading, data, error and collection handling.

Unified toolkit offering app lifecycle, device and app info, clipboard read/write/observe, network and keyboard monitoring, haptics, sensor observation, navigation, share-sheet and file pick/save helpers.

Unifies media selection for images, videos, and files with system-camera capture, streaming reads, lightweight file references, seamless single-call API, and no custom camera UI or extra permissions.

Parses and dereferences JSON Schema $ref pointers across files and URLs, merges allOf, preserves source locations, tracks original refs, handles circular references and authentication.

API wrapper for traQ bots offering coroutine-friendly DSL-style event handlers (onMessageCreated), message-reply utilities, token-based initialization, and a simple run lifecycle for quick bot setup.

Truly native date picker UI leveraging system pickers, auto-inheriting app theming; asynchronous suspend-style APIs for single or range selection, plus UI toolkit helper.

Transparent proxy converting non-stream OpenAI Responses and Chat Completions requests into SSE upstream streams, aggregating events in memory and returning single JSON responses, while passing through streaming requests unchanged.

Generate native splash screens from a single Gradle DSL, auto-producing per-density assets and launch assets; runtime API to preserve/remove splash until UI ready, with dark‑mode and per‑flavor wiring.

Type-safe, annotation-driven DataStore code generation producing zero-boilerplate compile-time implementations from simple interfaces; supports suspend and reactive reads, typed preferences, object serialization, and constructor/reflection instantiation.
