Got a text saying your Apple ID is locked? A delivery fee to pay? A grandchild who needs gift cards? Take a screenshot and share it to Hold Up. It reads the message right on your iPhone and gives you a plain answer: โข Likely scam โข Unclear โข Looks ok Then it names three things it noticed in that specific message, and tells you what to do โ usually: do not tap that link. NOTHING IS UPLOADED There is no account to make. Turn on Airplane Mode and it still works, because the whole check happens on your phone. Your history stays on the device. BUILT TO BE READ OUT LOUD Large type, high contrast, and one thing to tap. Made for the moment you are on the phone with a parent trying to talk them out of sending money. TWO TAPS FROM MESSAGES Screenshot the message, tap Share, tap Hold Up. That is the whole thing. Hold Up is a second opinion, not a guarantee. If money or passwords are involved, hang up and use a number you already know. Five free checks. Then $19.99 a year, or $2.99 a month. SUBSCRIPTION Hold Up Unlimited gives you unlimited checks. โข Yearly โ $19.99, billed once a year โข Monthly โ $2.99, billed once a month Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel it any time in your Apple Account settings.

Verdict
The clearest difference is in-app purchases: SealSkin at none against Hold Up's 2. Hold Up's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
