Volume Booster - Sound Control

Boost your phone's volume up to 200%, save sound profiles for every part of your day, and schedule them to apply automatically — all in one app, with no subscription.

VolumeMate is a volume booster, equalizer and sound profile manager built for Android users who are tired of their phone being too quiet, profiles that reset themselves, and apps that charge a subscription for features that should be a one-time purchase.

🔊 VOLUME BOOSTER — up to 200%

A clear, smooth gain you can set anywhere from 100% to 200%. Powered by Android's LoudnessEnhancer with peak compression so audio stays clean, not distorted. Perfect for quiet podcasts, soft videos, or hard-of-hearing scenarios.

🎚️ FULL VOLUME CONTROL — every Android stream

A separate slider for all 7 streams: Media, Ringer, Notifications, Alarm, Voice Call, System (UI sounds), and Bluetooth voice. One screen, every channel.

🎯 SOUND PROFILES YOU ACTUALLY USE

• Sleep – ringer down, alarm up

• Work – notifications low, media off

• Gym – media loud, ringer silent

• Driving – calls + media up, notifications muted

• Meeting – everything off but vibrate

• Or build your own. Unlimited profiles on Premium.

🎛️ 10-BAND EQUALIZER + BASS BOOSTER + 3D VIRTUALIZER

Shape your music with EQ presets (Pop, Rock, Classical, Jazz, Bass, Vocal, Movie, Game), boost the lows, and widen the stereo image — all global, applied to every app.

⏰ VOLUME SCHEDULER

"Apply Sleep at 22:30 every night." "Apply Work at 09:00 weekdays." Powered by AlarmManager — fires on time even with the app closed, and survives reboots.

🎧 SMART TRIGGERS

• Headphone plug → auto-apply your music profile

• Bluetooth device → apply Driving when your car connects

Every trigger has a "restore on disconnect" option.

🔒 VOLUME LOCK & VOLUME LIMITER

Pin every stream at the volume you want; the hardware buttons can't budge it. Or set a maximum cap per stream — perfect for a kids tablet, hearing protection, or stopping accidental loud music in public.

⏱️ PROFILE TIMER

Apply a profile for 15 / 30 / 60 / 120 minutes, then automatically restore the previous one. "Silent for the next hour" in two taps.

📊 DECIBEL METER (bonus)

Estimate ambient sound with the microphone, with safe / loud / dangerous zones. Educational only — useful for hearing-protection awareness.
