About this app

Measure how loud it is in dB with your phone's microphone, and stamp the moment as a record.
Leave it running overnight to see exactly when noise happened and how loud it got.

■ What you can do
• Instant measuring — big dB number, color level gauge, min/avg/max and a live graph
• Night mode — dims the screen so you can measure all night (charging tip, double-tap to exit)
• Save as a record — keep a session as one stamped record and add a note
• Nothing lost — saves every minute while measuring and resumes if the app closes
• Loud moments marked — finds sudden spikes above the background: count, time and the loudest one
• Noise log report — hourly average, maximum and loud moments, shared as an image (PNG), text or CSV
• Calibration — adjust ± dB to match your phone's microphone
• 15 languages

■ No audio is kept
The microphone is used only while measuring. Sound is turned into dB numbers on your device and discarded right away. Your records (numbers, times, notes) stay on your phone.

■ Ads and premium
• No ads when the app opens or while measuring (one banner at the top of the Records tab)
• Measure up to 10 minutes at a time for free — premium for your first 24 hours after install
• Watch one ad for 24 hours of premium: records up to 24 hours, reports and CSV

■ Please note
Readings come from a phone microphone and are for reference only. They do not replace a certified sound level meter or an official measurement.

• The ad button is hidden while premium is active
• When your connection comes back, the top of the Records screen recovers right away
• Changing the language no longer stops a measurement, and you land back on Settings
