About

Wait — should you trust this? Screenshot the text. Forward the email. Share the voicemail. Shieldr reads it and tells you straight: safe, suspicious, or a scam. No threat scores. No jargon. One word and a reason you could repeat to someone else over the phone. HOW IT WORKS Share anything suspicious right from the iOS share sheet, wherever you already are. You get one of three answers, plus a sentence explaining exactly what gave it away. Then report it to 7726, block the sender, or have Shieldr write the reply. WHAT YOU CAN CHECK Texts and screenshots · Emails · Voicemails (transcribed, then judged) · Links · Letters and physical mail, photographed page by page WHEN WE'RE NOT SURE If the image is unreadable or there isn't enough to go on, Shieldr says so rather than guessing. A verdict you can't trust is worse than no verdict. ON A CALL RIGHT NOW? A calm screen with big text and one instruction at a time: confirm nothing, hang up, call the real number yourself. LOOK OUT FOR SOMEONE ELSE The Family plan covers up to three people. Set it up on their behalf in about two minutes. You'll see that they checked something and how it came back — never who it was from, never what it said. WHAT WE SHARE, AND WHAT WE DON'T When you check a sender, the sender and the verdict go into a shared database, so the next person who checks that number gets an instant answer. The message itself never goes in — no wording, no content, nothing that could identify you. Your own scan history stays yours. WHAT'S GOING AROUND See the scams being reported most right now, drawn from what people are actually checking. Recognize the wave before it reaches you. SUBSCRIPTION Solo $9.99/month or $39.99/year. Family $14.99/month or $59.99/year for up to three people. No free tier, no ads — every check costs real money to run, and we'd rather charge you than make money off what we learn about you. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
