What it does
Everything you need to fix the audio. Nothing you don’t.
Four controls, one job: make the clip audible without turning it into noise.
Voice clarity
Speech sits forward and stays intelligible, even when the original recording is muddy or distant.
Bass boost
Bring back the low end on phone recordings, lectures and music that lost its weight.
No daily limit
Export as many clips as you need. The free plan stops at three exports a day; Pro removes the counter.
Privacy by default
The file stays on your iPhone.
Louden reads the clip you pick, applies the gain on device, and writes a new copy. Your media never touches a server — there is no server to touch.
- No account and no sign-in.
- No analytics SDK, no ads and no ad tracking.
- Your original file is never modified.

Prices shown in USD; the App Store displays your local price and handles the payment. The weekly plan renews automatically unless cancelled at least 24 hours before the period ends. Lifetime is a one-time purchase, not a subscription. Both plans are bought inside the app, not on this website. Read the Terms of Service.
How it works
Three taps to louder.
01
Pick a clip
Choose a video, voice memo or audio file from Photos or Files. Nothing is copied to the cloud.
02
Set the gain
Go up to 200% free, or 1000% with Pro. Add voice clarity or bass if the recording needs it.
03
Save the copy
Export a new file to Photos or Files. The original is left exactly as it was.
FAQ
Good questions.
Short answers here. The full list lives on the support page.
Does Louden upload my videos?
No. Louden processes every file on your iPhone. There is no account system and no media storage on our side, so your videos and audio never leave the device.
How do I cancel the weekly plan?
Open Settings → Apple ID → Subscriptions on your iPhone, choose Louden and tap Cancel. Deleting the app does not cancel the subscription. You keep Pro until the paid week ends.
What is the difference between free and Pro?
Free stops at 200% boost and three exports a day, and leaves out voice clarity and bass boost. Pro goes to 1000%, adds both effects and removes the daily limit.
I bought Pro. How do I get it on a new phone?
Install Louden, open the paywall and tap Restore. Your purchase is tied to your Apple ID, not to the device, so it comes back without paying again.
