RedFlag analyses language patterns, sender data, links, and known scam signatures and returns a score from 0–100.
Every score comes with a plain-English explanation — the specific signals that raised the score and which patterns are known scam indicators.
A 0–100 score isn't enough. We tell you exactly which signals triggered it and why — so you learn as you check.
We track what's circulating right now — HMRC texts, Royal Mail phishing, Netflix scams — and publish detailed breakdowns with screenshots so you know what to look for.
Millennials — this is for you. When your mum forwards a suspicious text, you check it with RedFlag, then tell her what to do. No technical knowledge required on her end.
We show our scoring logic. We explain every flag. There's no upsell, no bait-and-switch, no hidden bundle required. £5/month, straightforward.
