SuperBlaze27 ★★★★★ v1.0.1 2026-07-01
Apple is complicit
Apple iOS is as bad as (if not, worse) than Google browsers. I’m writing this review before I throw my phone in the trash. I’m kidding, at least for now, but this is the first app I’ve seen demonstrate to a great extent the variables apps can use to build a fingerprint. It’d be cool to see some recommendations as to how we can potentially reduce the surface that apps are able to access, if possible, and maybe a demonstration of (opt-in) fingerprinting via Firebase (crashlytics?) and the despicable persistent keychain data that can’t be deleted that apps use to fingerprint. Looking forward to future updates!

Eye opening!
When they told me that any app could see exactly when my phone was activated, write down to the second, it helped me comprehend how easy it is for them to identify me and track me. I mean, how many of my exact model of phone were activated at the exact second I activated my phone? This app is really starting to make me aware that I need to take steps to protect my privacy.
