NoiseLevel is a fun way to measure the sounds in your surroundings. Measure the sound level of the music you listen to, your kids playing or your office environment. NoiseLevel uses your iPhone's built-in microphone to first pick up sound and then displays it in dB (= decibels) on a status bar at the bottom of NoiseLevel's main screen. Sounds are also displayed visually as a balloon whose size and color change according to the level of the sound measured. See the balloon burst at high sound levels - you can also make it burst by creating a sharp, high sound, for an example by clapping your hands. Have fun experimenting! For best results, turn the iPhone so the microphone is pointing directly at the sound source. The screen flips accordingly. Disclaimer: NoiseLevel is fairly accurate but it should NOT be considered a professional sound level meter. The built-in microphone of the iPhone can only measure values between 35 to 110 dB and values may vary slightly between iPhones.

NoiseLevel's advantage is in-app purchases (none vs 2) and update cadence (fortnightly vs every 6 weeks). On review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Simple Markdown Editor holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: NoiseLevel has 28 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of NoiseLevel's written reviews are positive against 50% of Simple Markdown Editor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NoiseLevel ships an update fortnightly, Simple Markdown Editor every 6 weeks. The most recent releases landed on October 31, 2026 and November 7, 2026 respectively.
