9月8日的Volu: Per-App Volume Control应用程序分析

Tired of audio blasting every time you open a video app? Volu gives you precise, individual volume control for every app on your phone — automatically. Set custom sound rules and Volu applies them the moment you open an app. No more scrambling for volume buttons when Instagram autoplays a video or when Spotify kicks in too loud. FEATURES • PER-APP VOLUME RULES Assign a specific volume level to any app. Volu applies it instantly whenever that app comes to the foreground. • SYSTEM-WIDE PROFILES Automate your whole phone's audio, not just individual apps. Create device-wide profiles that trigger when you connect to Wi-Fi, change location, plug in headphones, start Android Auto, or pair a Bluetooth device. • ADVANCED CONDITIONS Link your app rules or profiles to specific triggers. Save your home Wi-Fi, work Bluetooth, or custom schedules. A rule can activate only when you are connected to a specific network or device. • GLOBAL RULES Set a fallback volume rule that applies to all apps that don’t have a custom rule assigned to them. • HEADPHONES & BLUETOOTH ONLY Want a rule to only apply when wearing earbuds? Enable this mode so Volu leaves your speaker volume untouched. • ALWAYS MUTE Some apps should never make noise. Silence them permanently every single time they open. • ANDROID AUTO SUPPORT Keep your car audio perfect. Automate your volume and profiles smoothly while driving. • QUICK SETTINGS TILE Toggle all your rules on or off instantly directly from your notification shade. HOW IT WORKS Volu uses Android's Accessibility Service API to detect which app is in the foreground and applies your saved volume rules instantly. No root required. PRIVACY FIRST Volu collects absolutely no personal data. Everything stays on your device — no accounts, no analytics, no internet connection required. DESIGNED FOR ANDROID Built with Jetpack Compose and a clean, dark-first Material You interface. Lightweight, battery-friendly, and out of your way. Note: Volu requires the Accessibility Service permission to detect foreground app changes. This is used solely to apply your volume rules and does not read screen content, keystrokes, or personal information.
