Volume Booster - Sound Booster

Phone speaker too quiet? Headphones still not loud enough at max volume? Volume Booster - Sound Booster makes your speaker and headphones louder than the system limit - and shows you clearly when something is holding the boost back. 🔊 ONE DIAL, 0 → 200% Phone volume and boost live on one single dial: 0–100% is your phone's volume, 100–200% is the boost. Turn it up in one smooth move and always know exactly where you are. ✅ PRE-FLIGHT CHECK BEFORE YOU BOOST Before boosting, the app checks the things that can keep the boost from working: • Phone volume isn't at max yet - fix it with one tap. • Bluetooth headphones keeping their own volume level. • Headphone volume limits on some phones. • The app you're playing from not accepting audio effects. 💚 BOOST HEALTH - ALWAYS VISIBLE A small status chip under the dial shows whether the boost is really applied: Ready to boost, Boost active, or exactly what needs attention. No guessing. 🔁 BOOST THAT STAYS ON Pause, resume, switch tracks, lock your screen - the boost engine watches playback and re-applies itself automatically. 🎚️ EQUALIZER, BASS BOOST & VIRTUALIZER • Up to 10 bands (adapts to what your phone supports). • Bass Boost and Virtualizer, with controls that match your phone's real capabilities. • Sub-bass switch for headphones. • 16 ready-made presets for music, movies and more. 🎧 DEVICE PROFILES Speaker, wired headphones and each Bluetooth device keep their own boost level and EQ, and switch automatically when you connect. 🩺 DIAGNOSTICS & APP COMPATIBILITY Not louder? Diagnostics explains why and how to fix it. App compatibility shows which apps can be boosted on your phone. Some apps use their own audio engine and can't be boosted - you'll know before you start. 🎵 QUICK CONTROLS • Mini player: play, pause, next, previous - no special permission needed. • Notification control to adjust boost without opening the app. • Booster memory: reapply your last level when you open the app. • Set your own maximum boost (5 - 30 dB). ⚠️ PROTECT YOUR HEARING Listening at high volume for long periods can damage your hearing and your speakers. Start low and increase gradually. Very high boost levels may cause distortion on some devices.
