Loudi: Volume Booster & EQ

Your phone has a volume limit. Loudi is the volume booster that gets you past it — and keeps the sound clean while it does.

One dial. Drag the ring, watch the number, done. No preset grid to hunt through, no menu to learn.

WHY THIS ONE IS DIFFERENT

Most volume booster apps promise a huge number and hand you distortion. Loudi runs a limiter the entire time, so you can push the dial and still hear music instead of crackle. Past the safe range the ring turns amber — you see the warning before you hear it.

The boost also stays on. Switch apps, skip a track, lock the screen: it keeps working. No going back into the app to turn it on again.

WHAT YOU GET

• Boost up to 4x louder — honest numbers, not a made-up percentage
• Limiter always on, so the sound does not break up
• Equalizer with per-band control, tuned to your device
• Three presets: Flat, Voice, Deep
• Bass booster and spatial width
• Sound profiles — save a setup, switch back in one tap
• Home screen widget — boost on or off without opening the app
• Light and dark theme, follows your system by default

MADE FOR

• Quiet videos where you cannot make out the dialogue
• Earbuds that are too soft on a bus or a plane
• Old speakers that need help
• Podcasts and audiobooks recorded low
• Games and movies that deserve more than the stock ceiling

WORKS WITH YOUR SPEAKER, HEADPHONES AND BLUETOOTH

Loudi boosts the device output as a whole, so it applies to whatever is already playing — a music app, a video app, a browser, a game. No root required.

NO ACCOUNT, NO SUBSCRIPTION, NO MICROPHONE

Loudi has no sign-up and no paid tier. Every feature is available from the first launch.

It does not request the microphone permission and cannot record audio — it attaches standard Android audio effects to the output and nothing leaves your phone. Notifications are optional: decline them and the boost still works exactly the same.

BEING STRAIGHT WITH YOU

A volume booster works with the hardware it is given. Loudi will not turn a tiny phone speaker into a stereo system, and no app can. What it does is take your device to its real ceiling and hold it there without the harshness you get from apps that simply crank the gain.

Some content is already mastered loud and has little headroom left. On those tracks you will hear less of a change. That is the recording, not the app.

HEARING SAFETY

Loudi can raise output well above the normal maximum. Extended listening at high volume can damage your hearing, especially with headphones. The limiter and the caution range are guides, not protection — please use a level that is comfortable.

Loudi is a volume booster, sound booster, equalizer and bass booster in one small app, built by people who got tired of ad-stuffed boosters that quit on you halfway through a song.
