Even when saving records is free, the app is not practical ### 2/5 — Can’t be right *2026-07-05, version 1.5* In the ocean the noise is in the dangerous level. Can’t be right ### 4/5 — Not very good *2026-06-21, version 1.5* Sometimes it is not very correct and my room is a quiet room but it is 70 or more ### 3/5 — Sprache *2026-06-04* man könnte noch unterschiedliche Sprachen möglich machen **Developer response:** Vielen Dank für dein Feedback und den Vorschlag! Die Unterstützung mehrerer Sprachen ist eine sehr gute Idee. Wir werden dies bei zukünftigen Verbesserungen der App berücksichtigen, um die Nutzung für mehr Nutzer zugänglicher zu machen. Danke, dass du uns hilfst, die App zu verbessern. ### 3/5 — Not very good *2026-05-02, version 1.5* Sometimes I only breathe but it is 70decibels ### 2/5 — Review *2026-04-15, version 1.5* 5star. Made mistake on stars ### 2/5 — App works, banner is ugh *2026-03-01, version 1.5* I like the simplicity of this app but what’s with the weird porny banner at the bottom of the screen? ### 1/5 — Absolut falsche Werte *2026-02-08* Angeblich über 100 dB bei Stille. Auch habe ich die Kalibrierung wie vorgeschrieben durchgeführt und dennoch falsche Werte. Letztendlich generiert diese App Gewinne durch Werbung und sonst nichts. Wie man es von android kennt! Schämt euch! **Developer response:** Vielen Dank für dein Feedback! Es tut uns leid, dass die Messwerte bei dir nicht zuverlässig waren. Die Genauigkeit kann je nach Mikrofon, Gerät und Umgebung stark variieren, auch nach der Kalibrierung. Wir arbeiten kontinuierlich daran, die Messstabilität und Genauigkeit zu verbessern 🚀 ### 5/5 — Ntf *2026-01-26* Magnifique app **Developer response:** Merci beaucoup pour votre retour ! 😊 Nous sommes ravis que vous aimiez l’application 🚀 ### 1/5 — Absolutely trash *2026-01-09, version 1.4* It’s very inaccurate, as when it was a silent bedroom, it said 47 db still, went up to only 60 when my phone was playing a diss track at max volume on the speakers, yet when I imitated a dragster noise, it goes up to 120?? Also, it crashes when it goes over 120 db, so it’s useless if you’re recording a concert or a plane taking off. ## Most critical reviews (10 lowest-rated) ### 1/5 — Read 142db for my idling exhaust *2026-08-13, version 1.5* Not physically possible ### 1/5 — Inappropriate ads *2026-08-13, version 1.5* AP shared porn ads ### 1/5 — Likely AI Slop *2026-08-11, version 1.5* I tested this application in a quiet room and it reported an unrealistic 45 dBA for the noise level, and worse, the displayed average was not even calculated correctly. ### 1/5 — Highly inaccurate *2026-06-16, version 1.5* While there is the ability to calibrate, it’s still very difficult to get an accurate reliable reading. Other apps without needing calibration performed better. ### 1/5 — 측정수준 *2026-06-09* 최악 **Developer response:** 피드백 감사합니다. 말씀해주신 내용은 더 나은 측정 정확도와 사용 경험을 위해 참고하겠습니다. 사용 중 불편한 점이 있다면 언제든지 알려주세요. ### 1/5 — Sucks *2026-05-30, version 1.5* Me and my friend Coley tried this and it was not accurate. I was talking a little bit loud and it said I was 120 in danger but whenever we try doing it outside and screaming, it only went up to like 110. This thing is not accurate at all, and it does not work. ### 1/5 — Didn’t work *2026-05-22, version 1.5* Asked for permission to use microphone over and over again. Gave permission but it just asked again! ### 1/5 — 갑자기 *2026-05-21* 갑자기 말하면 아무리 작게 해도 110은 넘어가네 이딴거 쓰지 마세요 ### 1/5 — Just use NIOSH… *2026-04-25, version 1.5* …Sound Level Meter. As far as I can tell all this app does on the free version is plaster the screen with ads, and freezes all the time not allowing continuous accurate monitoring. ### 1/5 — Médiocre *2026-03-14* Cela ne mesure pas bien le son. Les mesures ne sont pas précises **Developer response:** Merci pour votre retour ! Nous sommes désolés que la précision des mesures ne vous convienne pas. Les résultats peuvent varier selon le microphone du téléphone, l’environnement et le calibrage. Nous travaillons continuellement à améliorer la précision et la stabilité des mesures 🚀 ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2026-09-02, version 1.5* Just got this app, I’m shocked at how much background noise there is in my ‘quiet room’. Revealing a constant humming sound, I thought it was a problem with my ears, it’s not it’s really there. ### 5/5 — 좋음 *2026-06-27* 데시벨이 잘돼고 좋아요 **Developer response:** 좋은 리뷰를 남겨주셔서 감사합니다! 앱의 데시벨 측정 기능을 만족스럽게 사용하고 계시다니 기쁩니다. 보내주신 응원에 감사드리며, 앞으로도 더 나은 서비스를 제공할 수 있도록 노력하겠습니다. ### 5/5 — Très bonne application gratuite *2026-06-22* Je cherchais une application pour une évaluation temporaire du bruit généré par un climatiseur. L’application a fait le job. Simple à utiliser et m’a bien dépanné **Developer response:** Merci beaucoup pour votre avis ! Nous sommes ravis que l’application vous ait aidé à évaluer le bruit de votre climatiseur. Nous sommes heureux que vous l’ayez trouvée simple et pratique à utiliser. Merci pour votre soutien ! ### 5/5 — Does what it Says *2026-05-24, version 1.5* Does what it Says, nothing more. It’s all I wanted and nothing I didn’t. ### 5/5 — Oh no *2026-05-24, version 1.5* This is very very the best very the best, but the Wendy’s Frosty’s are obviously better NENEN how about W? ### 5/5 — Good! *2026-05-02* Good! **Developer response:** Thank you for your feedback! We’re glad you’re enjoying the app and appreciate your support. ::: ### 5/5 — One more small feature please *2026-04-29, version 1.5* Please add the ability to rename the sounds recorded. For instance the sound level at the station and inside the bus or at the barber. 💈 thanks. 😊 ### 5/5 — Gut funktionierende SchallMesser *2026-03-11* Der Schallmesser läuft stabil. Das kalibrieren geht einfach. Wobei die Einstellungen nur subjektiv sind. Macht Wasser soll! **Developer response:** Vielen Dank für Ihr Feedback! 😊 Es freut uns, dass der Schallmesser stabil läuft und die Kalibrierung einfach ist. Wir arbeiten weiter daran, die Genauigkeit und Einstellungsmöglichkeiten noch besser und objektiver zu gestalten 🚀 ### 5/5 — Trying to find noise in house. *2026-02-16, version 1.5* Oh yeah. The app works and it’s sensitive. ### 5/5 — Sound meter *2026-02-01, version 1.4* Excellent product. Just what I needed. Simple and economical. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
