Frequently asked
Does DecibelKit record audio?
No. It analyzes sound on-device to show a decibel reading and never records, saves, or uploads audio.
How accurate is it?
It’s a consumer estimate, not a certified instrument. Use the Calibration offset in Settings to align it against a reference meter if you have one.
What does DecibelKit Pro unlock?
A one-time purchase unlocks session History, the daily-dose Exposure dosimeter, Calibration, and CSV export. The live meter is always free.
I bought Pro on another device — how do I restore it?
Open Settings and tap “Restore Purchases.” Pro is tied to your Apple ID.
