Decibel Meter Pro is full of features sound level meter with exclusive accuracy of measurements and integrated Spectrum Analyzer. Calibrated with professional dB meter.
The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?
dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.
(Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.)

App内課金を無効
アプリを入れる前は勝手に課金されたとか言ってる人多くいますが、設定どうなってるんですかね。パスワード等何も入力なしにアプリ入れれる設定になってるんだと思いますが、私はそもそもアプリ内課金は無効に (制限)にしているので勝手に課金されるといった現象に遭遇してません。
アプリの方ですがまともに音量測れるアプリ無かったので助かってます。
しかしながら無音の部屋に居ても20db以下に下がらない。低い音ほど適当感ありますが…
ピークの周波数が表示されたり波があったりと便利です。
※レビューで何か特典あるかも知れないので星5ですが、実際は星3です。尚意味がないかも。

Thank you so much for your positive feedback 🙏🏻
勝手にアップデート課金された
使っていたら英語のポップアップが上がり、消そうと思って操作していたらアップデートする項目をタップしてしまいました。
そして運悪くホームボタンに指を置いていたため、なんのアラートもなく勝手に課金されてしまいました…
普通、アップデート課金するなら確認画面ありますよね?
完全に詐欺です。せっかく良いアプリだと思ったのに非常に悔しいですね。

Thank you for using dB Meter and sorry for the inconvenience.
It looks like you have started in-app purchase with Start Pro button and when you saw payment confirmation dialog you tapped at home button to close the app instead of tapping cancel button on the dialog. When you touch your touch ID Apple decided it as confirmation of purchase. it's the way iOS working. You might disable such a behavior in iOS settings.
勝手に1200円課金されます。
操作中に課金のポップアップが出て、閉じようとすると課金が発生します。悪質です。
もし課金してしまった場合はアプリ製作者ではなく、appleに問い合わせてください。私の場合、1200円返金されました。
