Most sound tools stop at the reading.

A decibel number does not tell you where to put your speakers, how to treat your room, or what to do next. LevelCheck is an acoustic advisor — guided checks, plain-English recommendations, and Fix-Verify so you know what to fix and whether it worked.

DJs

Run a booth check before your set. Spot speaker balance issues, monitor loudness in real time, and get quick fixes — no sound engineer needed.

Producers & studio engineers

Optimize monitor placement, check room modes, run signal-assisted room-response checks, and use the fix-and-verify workflow to confirm treatment changes actually worked.

Podcasters & creators

Run vocal booth and broadcast checks, track noise floor levels, and get plain-English advice on acoustic treatment and gear placement.

Venues & rehearsal spaces

Run quick room checks before doors open, save profiles for each space, and compare results over time to track improvements.

Acoustic advisor. Not just a meter.

Check. Fix. Verify. Metering included when you need it. No technical expertise required.

Live loudness meter

See current dB, peak, and average at a glance. A, C, and Z weighting. 7-band spectrum, RTA, Log, and Lin analyzer views.

Guided checks

Step-by-step guidance for setting up rooms, booths, and venues. Optimize placement, get acoustic treatment suggestions and more.

Actionable recommendations

After each check, you get a prioritized list of what to try first — plus a fix-and-verify workflow so you can confirm the change actually helped.

No. LevelCheck is local-first. All your data stays on your device, and no account is required to use any feature.
LevelCheck uses your iPhone's microphone with on-device signal analysis to provide reliable measurements for setup decisions, room optimization, and loudness monitoring. Pro users can connect an external mic for even greater precision.
Core measurement works offline. Some store-related actions (like purchase refresh/restore) may require connectivity.
No. LevelCheck processes audio in real-time to calculate levels and spectrum data. We never record, store, or transmit your personal data or raw audio.
