No subscription required to get started. WHAT YOU CAN ANALYZE Screenshot Any Suspicious Email Take a screenshot of an email in Mail, Gmail, or another app. FraudScope reads it using on-device OCR and explains what may be suspicious. Paste Suspicious Texts and Messages Got a text from "FedEx" about a package? A message from "your bank" about suspicious activity? Paste it into FraudScope. The app scores the risk and explains the tactic in plain language. Inspect Links Before You Tap See where a link really goes before opening it in your browser. FraudScope checks domain age, TLS certificates, redirects, and look-alike domains such as "amaz0n-secure.xyz." Link inspection contacts the destination site and a public domain-age service. You see a disclosure before any request is made. Live Call Shield (Pro) Put a suspicious call on speaker and tap Start Listening. FraudScope watches for scam tactics in real time. Caller ID can be faked, but the caller's script can still reveal common scam patterns. WHY FRAUDSCOPE Core Analysis Is On-Device Every analysis, including OCR on screenshots, runs locally.

Verdict
The clearest difference is rating: FraudScope at 5.0 against Acidity's 4.2. FraudScope also leads on update cadence (every 4 days vs every 4 months). Acidity's advantage is in-app purchases (none vs 4) and ratings volume (10 vs 1). On price and ads there is nothing between them.
