+## AI Testbench (`ai_testbench/`)
+
+Standalone Flutter desktop app for benchmarking and evaluating on-device LLM models before shipping them in the companion app. It tests the same prompts and schemas used in production (`chrono_ai_flow` package) against local GGUF models via `fllama`.
+
+### What It Tests
+
+| Benchmark | Service | Purpose |
+|-----------|---------|---------|
+| **Structured extraction** | `model_benchmark_service.dart` | Validates LLM outputs valid JSON matching `chrono_ai_flow` schema (intent, title, datetime fields) |
+| **Time extraction** | `time_extraction_benchmark_service.dart` | End-to-end: transcript → LLM extraction → `chrono_dart` parsing → resolved `DateTime` |
+| **Correction** | `correction_benchmark_service.dart` | Verifies LLM can fix common STT errors (homophones, filler, punctuation) |
+
+### Running Benchmarks
+
+```bash
+cd ai_testbench
+flutter pub get
+
+# Interactive GUI
+flutter run -d linux
+
+# Headless (compiled for consistent timing)
+flutter build linux --release
+./build/linux/x64/release/bundle/ai_testbench --headless --output results.json
+./build/linux/x64/release/bundle/ai_testbench --headless-time --model Qwen3.5-2B-Q4_K_M.gguf
+./build/linux/x64/release/bundle/ai_testbench --headless-correction --model-dir models/
+```
+
+### Key Files
+
+- `lib/main.dart` — Entry point with headless mode dispatch (`--headless`, `--headless-time`, `--headless-correction`)
+- `lib/services/llm_service.dart` — `fllama` wrapper (`LlmService`) for inference with configurable parameters
+- `lib/prompts/` — Prompt templates (delegates to `chrono_ai_flow` for production prompts)
+- `benchmark_results/` — Saved benchmark summaries (Markdown)
+
+### Dependencies
+
+- **fllama** — Flutter llama.cpp bindings for on-device inference
+- **chrono_ai_flow** — Shared prompt templates and JSON schema (local package at `../packages/chrono_ai_flow`)
+- **chrono_dart** — Natural language time expression parsing
+
+### Notes
+
+- GGUF model files go in `models/` (gitignored — download separately from HuggingFace)
+- Native `.so` libraries go in `native_libs/` (gitignored — build from llama.cpp if using the CLI `bin/` runner)
+- Test cases are defined inline in the service files — add new cases there
+- The testbench shares the same `chrono_ai_flow` package as the main app, so prompt changes are tested against both

+# Changelog
+
+## [1.1.0] - 2026-02-17
+
+### What's New
+- The firmware update screen now shows only the firmware compatible with your watch, making updates simpler and safer. A new option for watches with a rotated display is also available.
+
+### Fixes & Improvements
+- Fixed an issue on iOS where Bluetooth permission was not requested at the right time, which could prevent the app from connecting to your watch.
+- Improved reliability when loading firmware update files from local storage.
+- Fixed app icon, splash screen, and launcher icon display on Android and iOS.
+
+## [1.0.0] - 2026-02-12
+
