User Reviews

User reviews are mixed. Many praise the app for being free, easy to use, and sometimes helpful for quick, real-world noise checks and educational use (voice projection, office noise, RV generator). However, a strong recurring theme is inaccuracy and unreliability: readings often appear too high (sometimes by ~20 dB), and the app can fail to provide measurements or save data. Reviewers also complain about advertising and potential bait-for-clicks, plus spelling/grammar errors on a single-screen UI. Overall, it may be useful for rough checks, but not a dependable replacement for a real SPL meter.

Pros

Free to use (no subscription or annual fee)
Easy to use with a simple, one-screen interface
Useful for real-world tasks (voice projection practice, measuring office noise, RV generator testing, etc.)
Helpful for quick, basic sound level checks and educational use

Cons

Inaccurate readings: often off by tens of dB, can show dangerous levels or be higher than a true meter
Reliability issues: sometimes doesn’t work or fails to provide readings; can't save measurements
Advertising heavy / bait-and-switch and affiliate links interfere with experience
UI/grammar quality concerns: noticeable spelling mistakes and poor wording in the app
