Level is a fast, honest sound-level meter for iPhone. A big live decibel reading, plus Leq, Min, L90, and Peak alongside it — toggle on only what you need. A built-in reference generator and calibrated-mic support are there for speaker work or true SPL. One clean instrument, not a busy suite. FEATURES Big decibel reading — A/C/Z weighting, Fast (125 ms) or Slow (1 s) response Four toggleable stats in a 2×2 grid: Leq (energy-average), Min (quietest moment), L90 (background level — exceeded 90% of the time), Peak (true instantaneous peak). Always computed; show only what you need Peak-hold "Max" — a marker holds the loudest moment; tap to reset Reference signals: pink noise, white noise, ten octave tones (31.5 Hz–16 kHz), level-matched. 1 kHz tone pairs with a 94 dB calibrator Play any output — iPhone speaker, AirPlay, Bluetooth, or USB — while the meter keeps reading Calibrated-mic support: Dayton iMM-6C, miniDSP UMIK-1/UMIK-2/EARS, Behringer ECM8000, REW. Frequency correction plus a true-SPL anchor from the file's 1 kHz sensitivity Manual calibration offset Share card — current reading, your enabled stats, and the level bar Full VoiceOver support No account, no analytics, no third-party SDKs, no in-app purchases, no network connections HOW IT WORKS Open Level, allow the microphone, and read the room. Turn on Leq, Min, L90, and/or Peak in Settings → Readings to see them beside the live number in a 2×2 grid. Tap the meter to reset Max and every stat. For speaker work, tap play to send a reference signal to any output — pink noise for level-setting, white noise for tweeters, an octave tone for room modes, or the 1 kHz tone against a 94 dB calibrator. Long-press play (or use Settings) to switch. With the built-in mic, readings are approximate but honest and well-behaved. A calibrated USB mic and its cal file give true SPL. Either way, Level is a measurement tool, not a certified Type 1/2 instrument. GREAT FOR Checking if a room, party, nursery, or workspace is too loud Home theater/hi-fi — matching channels, setting levels, dialing in a subwoofer Car audio — matching and balancing components Live-sound hobbyists and DIY speaker builders Anyone who wants an honest number, without a pro measurement suite PRIVACY Audio is measured live only — never recorded, written to disk, or transmitted. No account, no analytics, no in-app purchases, no network connection at all. QUICK START Open Level, allow the microphone Read the big number (A-weighted by default) Settings → Readings: turn on Leq/Min/L90/Peak to add them to the grid Tap the meter to reset Max and every stat For speaker work: tap play to send a reference to any output; long-press to switch signals IMPORTANT Level is a general-purpose meter, not a certified Type 1/Type 2 instrument. Built-in mic readings are approximate; a calibrated USB mic with a cal file gives true SPL. ## Key features - Live decibel reading - Built-in pink-noise generator - Peak-hold maximum marker - A, C, & Z frequency weighting - Manual calibration offset - Multiple color themes ## Frequently asked questions about Level ### Does Level have ads? No, Level is completely ad-free. The app explicitly states it has no advertisements, ensuring an uninterrupted user experience. ### What is the accuracy of Level's readings? The app notes that the iPhone's built-in microphone is not a calibrated instrument, so absolute readings are approximate. Level functions as a well-behaved relative meter, ideal for level-matching, and can be trimmed with a manual offset against a known reference. ### Can Level be used offline? Yes, Level can be used offline. It makes no network connections at all and requires no account or signup, making it fully functional without internet access. ### How often is Level updated? The latest version of Level is 1.2, which was last updated on July 1, 2026. This indicates a recent update, suggesting active development and maintenance. ### What devices does Level support? Level is currently supported on iPhone devices. The app's compatibility is limited to iOS smartphones at this time. ### Is Level suitable for beginners? Yes, Level is designed for anyone who wants to set and match levels quickly without a complex professional measurement suite. Its straightforward interface and clear readings make it accessible for both hobbyists and professionals. ### Does Level collect any user data? No, Level prioritizes user privacy and collects no data. It has no accounts, no analytics, and no third-party SDKs, ensuring your audio measurements remain private. ### What is the price of Level? Level is completely free to download and use. There are no in-app purchases or hidden costs associated with this utility. ## Version history (last 4 releases) ### 1.4 — 2026-08-24 Level 1.4 turns the live number into a real meter. • Four new secondary stats — Leq, Min, L90, and Peak — toggle any combination on in Settings → Readings; they show in a clean 2×2 grid beside the live reading. All four are always computed, whether or not you show them. • L90 is new: the level exceeded 90% of the time — the standard way to describe a steady background level, not just the loudest or quietest moment. • Peak is new: the true instantaneous peak, independent of the meter's Fast/Slow response — a different, faster-moving number than the existing peak-hold Max, and useful alongside it. • The Share card now mirrors whatever's on the main screen — the current reading plus your enabled stats, in the same 2×2 layout. • Two accuracy fixes: the first reading after launch no longer shows a false spike while the frequency-weighting filter settles in, and Peak no longer jumps to an unrelated value each time you tap the meter to reset. ### 1.3 — 2026-07-17 Level 1.3 makes a good sound-level meter into a useful one. • Session Leq — the energy-average level pros and regulators quote — sits beside the live number, and resets when you clear Max. • Reference signals built in: pink noise, white noise, and octave-band tones from 31.5 Hz to 16 kHz. All level-matched, so switching doesn't jump the meter. The 1 kHz tone pairs with a 94 dB acoustic calibrator. Long-press the play button (or use Settings) to switch. • Calibrated-mic support expanded: alongside the Dayton iMM-6C, Level now imports cal files for miniDSP UMIK-1, UMIK-2, EARS, Behringer ECM8000, and REW exports. Frequency correction is applied; with a 1 kHz sensitivity in the file, absolute level is anchored to true SPL. • Cleaner look: white type, an orange meter bar, one confident color story throughout — the color-theme setting has retired. • Full VoiceOver support — the meter announces cleanly for eyes-off use. Under the hood: adopted Swift 6 (with fixes for a crash the play button could trigger under strict concurrency), safer cal-file imports, and a raft of small hardening from an adversarial review. ### 1.2 — 2026-07-01 Share your readings — tap the share icon to export a capture card showing your current level and session peak. Great for documenting a room, a mix, or a system check. Settings get a refresh: cleaner native iOS controls throughout, and a smoother slide-up sheet instead of a separate screen. Updated splash screen and other minor visual refinement. ### 1.0 — 2026-06-23 No release notes. ## More apps by Carl Sieber - [Pull: Acceleration Tracker](https://appshunter.io/ios/app/pull-acceleration-tracker/id6777791130) - [Lean: Inclinometer](https://appshunter.io/ios/app/lean-inclinometer/id6780365308) - [Grip: G-Force & Cornering](https://appshunter.io/ios/app/grip-g-force-and-cornering/id6781833028) - [Sweep: Speaker Tuning](https://appshunter.io/ios/app/sweep-speaker-tuning/id6784438195) All apps by Carl Sieber: https://appshunter.io/developer/6777791133 ## Related topics [sound check level](https://appshunter.io/ios/topics/sound-check-level) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
