Shieldr

Shieldr checks suspicious messages for you. Share a text, screenshot, email, voicemail, link or a photo of a letter from the iOS share sheet, and Shieldr gives one of three answers: safe, suspicious or scam, plus a plain-language sentence explaining what gave it away.

Voicemails are transcribed and then judged. Links are checked against Google's list of known malicious sites. When there isn't enough to go on, Shieldr says so instead of guessing.

After a verdict you can report the message to 7726, block the sender, or have Shieldr draft a reply. Family plans let you help parents or relatives check messages too.

Shieldr is a paid subscription app for iPhone.
