 - **Stability + auto-confirm** — 10s stable wait + 5s countdown before confirming
 - **Real-time status** — Scale connection indicator always visible in the header
 - **Multi-protocol** — Supports Bluetooth SIG Weight Scale, Body Composition, Xiaomi Mi Scale 2 and 100+ models
- **Built into kiosk (v1.6.0+)** — BLE gateway runs as an integrated foreground service inside the [EverShelf Kiosk](evershelf-kiosk/) app; no separate APK needed.
+- **Built into kiosk (v1.6.0+)** — BLE gateway runs as an integrated foreground service inside the [EverShelf Kiosk](evershelf-kiosk/) app; no separate APK needed. The standalone gateway app in [`evershelf-scale-gateway/`](evershelf-scale-gateway/) is deprecated but kept for non-kiosk use cases.
 ### 📺 Android Kiosk Mode (Add-on)
 - **Dedicated tablet app** — Full-screen WebView wrapper for wall-mounted kitchen tablets
@@ -352,35 +350,10 @@ The application uses no build tools — edit files directly and refresh.
 ## 📋 Roadmap
-### High Priority
+- [ ] User authentication / multi-user support
- [ ] **Cooking mode — 3D wheel JS** — swipe navigation, gyroscope tilt, haptic feedback
+- [ ] Offline mode with service worker
- [ ] **Cooking mode — step timers** — auto-detect "X minutes" in recipe steps, countdown + alert
+- [ ] Export/import inventory data
- [ ] **Push notifications** — daily expiry alerts via PWA Service Worker + VAPID
+- [ ] Notification system (Telegram, email) for expiring products
 - [ ] **Quick search / quick-add bar** — always-visible search above the nav, PWA shortcuts
 ### Medium Priority
 - [ ] **Receipt OCR → bulk add** — photo of receipt → Gemini Vision → auto-fill inventory
 - [ ] **CSV/JSON export & import** — download/upload inventory from Settings
 - [ ] **Custom storage locations** — user-defined locations beyond Fridge/Freezer/Pantry
 - [ ] **Multi-user support** — PIN-based user distinction, action log with user label
 - [ ] **AI optimal purchase prediction** — suggest "buy X units of Y within Z days"
 - [ ] **Price history sparklines** — per-product price chart from the AI cache data
 ### Low Priority / Nice to Have
 - [ ] **Dark mode** — CSS custom properties are already structured to support it
 - [ ] **Full offline mode** — Service Worker cache to show inventory read-only when server is down
 - [ ] **French & Spanish translations** (`fr.json`, `es.json`)
 - [ ] **Swipe actions on inventory rows** — swipe left to use/discard, right to edit
 - [ ] **PHP unit tests** — PHPUnit coverage for shelf-life, price calc, and key helpers
 ### Completed ✅
 - ✅ AI price estimation in shopping list
 - ✅ Server heartbeat + offline banner
 - ✅ In-app bug reporter → automatic GitHub issue creation
 - ✅ Cooking mode (start, steps, 3D wheel CSS)
 - ✅ Kiosk ⚙️ Settings overlay button (replaces Android native button)
 - ✅ Adaptive consumption anomaly detection
 - ✅ CI/CD pipeline (PHP lint, JS lint, Docker build, Trivy security scan)

 # ~~EverShelf Scale Gateway~~ — DEPRECATED
 > ⚠️ **This app is deprecated and no longer maintained.**
 >
 > As of **EverShelf Kiosk v1.6.0**, BLE scale support is fully integrated into the kiosk app itself. You no longer need to install or configure this separate gateway app.
 >
 > **If you are using the EverShelf Kiosk app** → the scale gateway runs automatically as a background service. Configure your Bluetooth scale in **step 4 of the setup wizard**.
 >
 > **If you are NOT using the kiosk app** (standalone Android tablet) → you may still use this APK, but no new releases will be published.
 ---
 # EverShelf Scale Gateway (legacy)
 > Android gateway app that bridges Bluetooth LE smart scales with EverShelf via WebSocket.
 ---
 ## How it works
 ```
 Smart Scale ──(BLE)──► Android Gateway App ──(WebSocket/LAN)──► EverShelf Server ──(SSE)──► Browser
 ```
 The app runs a local WebSocket server (port **8765**) on your Android device. The EverShelf server connects to it via a server-side relay (`api/scale_relay.php` SSE + `api/scale_ping.php` WebSocket client), avoiding mixed-content (HTTPS→WS) issues. Weight readings are streamed to the browser in real time.
 > **Kiosk integration (v1.6.0+):** The gateway is now **built into the EverShelf Kiosk app** as a foreground service. This separate app is not needed when using the kiosk.
 ---
 ## Supported scale protocols
 | Protocol | Service UUID | Notes |
 |---|---|---|
 | **Bluetooth SIG Weight Scale** | `0x181D` / char `0x2A9D` | Most compatible; works with most smart scales |
 | **Bluetooth SIG Body Composition** | `0x181B` / char `0x2A9C` | Reports weight + body fat %, BMI |
 | **Generic fallback** | Any notifiable characteristic | Auto-heuristic parsing for 100+ models |
 ### Verified compatible scales (community list)
 - Xiaomi Mi Body Composition Scale 2
 - Renpho Smart Body Fat Scale
 - INEVIFIT Smart Body Fat Scale
 - Any OpenScale-compatible scale (see [openScale supported devices](https://github.com/oliexdev/openScale/wiki/Supported-scales))
 > **Your scale (B09MRXVBV6):** If it implements the standard BLE Weight Scale or Body Composition profile (very likely for modern Amazon smart scales), the gateway will connect automatically. If not, check the [openScale wiki](https://github.com/oliexdev/openScale/wiki/Supported-scales) and open an issue.

 ## Download
 Download the latest APK directly: **[evershelf-scale-gateway.apk](https://github.com/dadaloop82/EverShelf/releases/latest/download/evershelf-scale-gateway.apk)**
 ---
 ## Requirements
 - Android **7.0** (API 24) or later
 - Bluetooth LE (BLE) support
 - Both the Android device and the device running EverShelf must be on the **same Wi-Fi network**
 ---
 ## Setup (step by step)
 ### 1. Install the APK
 Download and install the APK from the Releases page. You may need to allow "Install from unknown sources" in Android settings.
 ### 2. Launch the app
 The app starts the WebSocket gateway server immediately. You will see the **gateway URL** (e.g. `ws://192.168.1.100:8765`) at the top.
 ### 3. Connect your scale
 Tap **"Cerca Bilance Bluetooth"** (Find Bluetooth Scales). Make sure your scale is turned on. Tap it in the list to connect.
 ### 4. Configure EverShelf
 In EverShelf → ⚙️ Settings → **⚖️ Bilancia Smart**:
 1. Enable the toggle
 2. Paste the gateway URL shown in the Android app
 3. Tap **"Testa connessione"** — you should see ✅
 ### 5. Use it
 When adding or consuming a product with unit **g** or **ml**, a **"⚖️ Leggi dalla bilancia"** button appears. Tap it, place the product on the scale, and the weight is filled in automatically.
 ---
 ## WebSocket protocol reference
 All messages are JSON. The server sends these to connected clients:
 ```json
 // Scale status update
 {"type":"status","state":"connected","device":"Mi Scale 2","battery":85}
 {"type":"status","state":"disconnected"}
 // Weight reading (broadcast continuously while scale is active)
 {"type":"weight","value":72.50,"unit":"kg","stable":true,"timestamp":1712345678000}
 // Response to ping
 {"type":"pong"}
 ```
 Clients can send:
 ```json
 {"type":"get_status"}   // Request current status
 {"type":"get_weight"}   // Request next stable weight reading
 {"type":"ping"}         // Keep-alive
 ```
 ---
 ## Build from source
 ### Prerequisites
 - Android Studio Hedgehog (2023.1) or later
 - Java 8+
 ### Steps
 ```bash
 # 1. Clone the repo
 git clone https://github.com/dadaloop82/EverShelf.git
 cd EverShelf/evershelf-scale-gateway
 # 2. Download the Gradle wrapper (if not included)
 gradle wrapper --gradle-version 8.4
 # 3. Build debug APK
 ./gradlew assembleDebug
 # APK is at: app/build/outputs/apk/debug/app-debug.apk
 ```
