Check First — Scam Protection
Check First is a scam-protection app for iPhone, built for families. Paste a suspicious message, email or web address — or add a screenshot — and Check First looks for common scam warning signs and explains what it found in plain language. Results are estimates to help you pause and check, never a guarantee, and anything suspicious should always be verified independently.

Results are estimates — always verify independently
Check First helps you pause and look for warning signs. Its results are estimates of scam likelihood, never a guarantee — and a clear result does not prove a message is genuine. Before acting on anything suspicious, verify it independently using contact details you already know and trust.
How does a check work?
Choose what to check
Pick a message, email, website or screenshot — whatever you or a family member has been sent.
Check First looks for warning signs
The content is checked against common scam warning signs, like pressure to act immediately or impersonating a trusted organisation.
Read the result — an estimate, explained
You get an estimated scam likelihood with each warning sign explained in plain language. It is an estimate, never a guarantee.
Verify independently before acting
Whatever the result says, verify suspicious content through contact details you already trust — never the ones in the message itself.
Warning signs, explained in plain language
Instead of a bare verdict, Check First lists the warning signs it found — pressure to act immediately, impersonating a trusted organisation — and explains why each one matters.
Every result is an estimate of scam likelihood, stated plainly as one. A high-confidence result is still an estimate — and when no obvious warning signs are found, Check First says clearly that this does not prove a message is genuine. Always verify suspicious content independently, using contact details you already trust.
What if no warning signs are found?
Check First says so — and says clearly that this does not prove the message is genuine. Even genuine-looking messages can be part of a scam, so the app still recommends verifying if anything feels off.
Built for families
Add family members and send them a check to review before anyone acts. Requests to review and replies are visible to the family group — useful when a relative isn't sure about a message they've received.
A safe phrase for your family
Families can set a shared safe phrase — a simple way to verify that a call or message claiming to be from a family member really is.
Privacy-led by design
Checks are analysed once and stored nowhere, with no tracking and no ad profiling. Checking something you have been sent should not create a new privacy problem.
