Volume Booster Sound Equaliser のアプリ分析 11月9日

Boost your phone's volume up to 200%. A real 10-band equalizer, proper bass boost, stereo surround, and a premium-feel interface. VolumeBoost is a volume booster and sound amplifier built by people who got tired of every booster app on the Play Store being buried under banner ads, video ads, and paywalls. If you've uninstalled a dozen of them already, you know what we mean. This one just works. WHAT IT DOES → Amplifies your system audio beyond the default Android maximum, up to 200%. → Works for music, videos, games, podcasts, audiobooks, calls over speakerphone, alarms, and ringtones. → Boosts volume on phone speakers, wired headphones, USB audio, and Bluetooth speakers and earbuds. → Improves cheap speakers and weak headphones noticeably — try it on old earbuds or a budget Bluetooth speaker. REAL AUDIO FEATURES → 10-band graphic equalizer (31 Hz to 16 kHz) with 11 presets: Flat, Pop, Rock, Jazz, Classical, Hip-Hop, Electronic, Vocal, Bass, Treble, and Custom. → Bass booster with fine-grained control — feel the low end without muddy distortion. → Stereo surround (virtualizer) that widens the soundstage on headphones. → 7 reverb presets: small room, large room, medium hall, large hall, and plate. → 8 one-tap sound modes: Silent, Whisper, Normal, Loud, Music, Movie, Game, MAX. Plus a Custom slot to save your own settings. → Live music spectrum visualizer that reacts to what's actually playing. FAST CONTROLS → Persistent notification with volume up, volume down, and power controls. Keeps the booster running when you close the app. → Two home-screen widgets: a compact 2x1 and a full 4x2 with quick mode buttons. → Detects what's currently playing (Spotify, YouTube Music, any music app) and shows the track with play, pause, and skip controls. Optional. → Shows your current audio route — phone speaker, headphones, or Bluetooth device name. → Hardware volume keys control the boost level when the app is open. DESIGNED PROPERLY A dark, premium-feel interface inspired by professional audio gear. The whole UI glows warmer as you boost louder — a subtle cue for your ears, not a nag. No cartoon speakers, no neon gradients, no ad banners covering the controls. ABOUT YOUR HEARING High volume, especially on headphones, can damage hearing over time. We ship with a soft volume cap you can adjust (150%, 175%, 200%), an auto-reduce option when you plug in headphones, and on-screen guidance when you push into the higher ranges. This is a tool, not a dare. PRIVACY VolumeBoost works 100% offline. No accounts, no analytics, no tracking, no ads, no data collection, no servers. Your settings stay on your device. WHY BUILT THIS WAY This app was built by an independent studio that doesn't run ad networks or subscription funnels. If that matters to you, welcome. DEVICE NOTE Audio effects rely on Android's built-in audio framework (LoudnessEnhancer, Equalizer, BassBoost). Some devices and OEMs restrict access to system-wide audio effects. If yours does, the app will tell you transparently instead of pretending.
