The latest update consolidated five identification tools into a single application, resulting in a 0.74 star rating increase on Android.

How it played out

Retrospective analysisSeptember 28, 2026

The average rating improved by 0.74 stars, driven primarily by a high volume of positive sentiment on Android following the consolidation of identification tools. Despite this, users report significant friction regarding aggressive ad placement and billing practices, including allegations of unauthorized annual charges after trial sign-ups. Momentum appears mixed as technical reliability issues and monetization complaints offset the gains from the expanded feature set.
