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
• Arrive at a place → apply Work when you get there, then switch again when you leave
Every trigger has a "restore on disconnect" option.

📍 LOCATION TRIGGERS
If you set up a location trigger, VolumeMate uses your location data, including in the background when the app is closed or not in use, to notice when you arrive at or leave the places you save and switch your sound profile. It stays off until you add a location trigger and allow it. Your saved places and your location stay on your phone and are not sent to us.

🔒 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.

📦 BACKUP & RESTORE
Export every profile to a JSON file, restore on a new phone. No cloud account required.
