What's New in dB Decibel
1.3.0
August 29, 2026
The line that explains the advertising ran off the edge of the screen at larger text sizes. It now wraps and stays readable. A refund now removes Pro, so the app matches what you actually own. The advertising SDK only starts once you have given consent, and the store text no longer claims there is no tracking.
