Ratings and reviews

The ads are infrequent, which is great. This app should come to Googlebook this fall, in my honest opinion, if the developer wants! :) Edit: I meant the upcoming Googlebook from Google.

SIMGUARD exceeded my expectations. It’s fast, clean, and feels like a genuinely premium security app. With banking, email, social media, crypto, and 2FA all connected to our phones, the security monitoring and clear alerts are extremely useful. It’s polished, easy to understand, and packed with great features. Definitely worth downloading.

As a crypto user, SIMGUARD detected an address poisoning attack in my wallet history before I noticed it. The alert explained exactly what was happening and made me verify the correct wallet address before my next transfer. That one alert likely saved me from a $50,000+ loss. Highly recommended.
