Loupe hit the App Store on June 8, 2026, offering a detailed look at what iPhone apps can silently gather.
The app lists every detectable fingerprinting signal, including the device language, battery health, list of installed apps, and persistent identifiers such as the IDFA. It pulls this data from the same APIs that third‑party apps use, then displays the results in a clear, itemised view.
Why it matters: privacy‑conscious users now have a concrete way to audit the data their apps are harvesting, something that has previously required technical digging. By exposing the breadth of information available to developers, Loupe forces a conversation about what data collection is acceptable on a locked‑down platform.
At a time when iOS privacy claims are under scrutiny, an app that simply shows the raw signals is a modest but useful reality check.
