What's New in Noise Meter
1.1.1
September 7, 2026
localized name and subtitle ONLY. nothing else changed. To reviewers, Please don't "shoot down a strawman". This app do not use HealthKit, nor CareKit - it is against our core value of "Security First". I have tested and use chatgpt and claude to verify it. But I welcome any constructive objections with screenshots or evidence to make sure no HealthKit/CareKit is completely absent. If you can use LLM to test and point out any evidence, that will make our app most secure in the world.
