LevelCheck is built around a simple workflow. You do not need to know what you are doing before you start.
Open the app and you are measuring immediately. The live meter shows the current dB level, updating in real time. There is nothing to configure before this works.
You can see the current level, peak, and average at a glance. The spectrum view shows a sense of where the sound is concentrated — low, mid, or high frequencies.
Hears sound roughly the way humans do. Better for general listening checks and everyday loudness awareness.
Counts bass energy more than A-weighting does. Useful when you want to include the full weight of low-frequency sound.
About accuracy: LevelCheck uses your iPhone's built-in microphone and heuristic DSP. This is good for practical guidance and awareness. It is not intended as formally calibrated or certified measurement. For most creator, DJ, and studio uses, the level of useful information is more than enough for setup decisions.
Guided checks are the core of LevelCheck. Instead of leaving you to interpret a reading on your own, the app walks you through a structured set of steps and then tells you what it found.
Each check is designed for a specific type of setup or question. You follow the instructions — where to stand, what to do — and the app performs a heuristic comparison.
A fast check of loudness, basic tonal balance, and obvious problems. Good as a first pass for any space you are working in.
Takes about 2–3 minutes
Built for DJ booths and similar performance setups. Looks at loudness levels, spectral balance, and likely room reflections.
Takes about 3–4 minutes
Checks whether left and right channels feel balanced at your listening position.
Takes about 2 minutes
Helps you see whether your listening position is affecting what you hear.
Takes about 3 minutes
After a check, LevelCheck gives you a prioritised list of what to try next. Not a wall of numbers. Not a raw frequency graph. A short, clear set of actions in plain English.
The most important suggestion is pinned at the top. Supporting observations appear below it. If you want more detail, you can expand any finding to read more.
The recommendations are based on what the check found — not generic advice. They are meant to be actionable and honest about what can be fixed.
Saving results is how LevelCheck pays off over time. Once you assign sessions and checks to a saved profile, you can compare earlier and later results.
The comparison view shows what changed between two results — letting you see exactly how that new acoustic panel or speaker position affected the space.
