A grandparent scam protection app: what it does and what to check
Updated October 16, 2026 · 6 min read
The grandparent scam works because a loved voice asks for help and the grandparent wants to act fast. A protection app can’t stop the call, but it can give your family one calm thing to do instead of sending money: check with the real person. Here is how that works and what to look for before you choose one.
What the app should do for a grandparent
- Make the safe move the easy one. Hang up, then check, in one or two steps.
- Work on the phone they already have. Many grandparents will not install a new app.
- Put the real person in the loop. The check should reach the grandchild’s own phone, not just the caller.
- Teach the habit. The best protection is the grandparent having done this once before, calmly.
How Countersign works for grandparents
A grandparent who gets a worrying call hangs up and texts “CHECK” and the grandchild’s name. Countersign asks the real grandchild, on their own phone, whether it was them. The answer comes back by text. No app is needed on the grandparent’s side. In the other direction, the family can send a practice call (with the grandparent’s permission) so the first time they meet the scam is a safe rehearsal.
Before you buy any app, ask
- Does it work with just text messages, for the least technical relative?
- Does the real person confirm on their own phone, or just the person asking?
- Does it avoid promising total protection? Any tool that claims total protection should worry you.
- What happens to your family’s phone numbers and voice data? Read the privacy page.
- Can you cancel easily, and is the free version actually useful?
What an app doesn’t replace
- The rule at home: no money is sent without checking, however urgent the call sounds.
- A saved list of real numbers to call back.
- Bank settings: alerts for large transfers and a trusted contact.
- Telling your grandparent that being targeted is not their fault.
Cost

Frequently asked questions
Is there an app that protects grandparents from the grandparent scam?
Apps like Countersign help by letting a grandparent check with the real grandchild. No app stops the call itself, so it should be paired with a family rule: no money without checking.
Does my grandparent need a smartphone?
Not for Countersign. A grandparent can text “CHECK” and a name from any mobile phone.
What should a grandparent do if they already sent money?
Contact the bank right away, then report it to the FTC at reportfraud.ftc.gov or your national fraud service. Speed matters.
