The Best Scam Blocker Apps for Seniors, Compared
Five apps compared. Honest math. We'll tell you when Tiina isn't the answer.
Most caregivers should run two apps on a parent's phone, not one. A call blocker (Nomorobo at $1.99/month is the cleanest pick) catches the known-bad numbers before they ring. Tiina ($24.99/month) is the calm voice your parent opens after a call that got through, when they aren't sure if it was real. They solve different problems and they don't compete. RoboKiller is fine if your parent likes the prankback feature. Truecaller we'd skip for a parent's phone — its caller ID runs on a crowd-sourced database model we walk through below. Aura is overpriced for what most families need.
The question we get from caregivers more than any other, almost always at the end of an email about something else: "What app should I put on her phone?"
The honest answer is: that depends on what you mean by scam. A robocaller dialing ten thousand numbers a day is a different problem than a stranger at 2 AM pretending to be your nephew. A tech-support pop-up is a different problem than a man who says he's from Medicare. No single app solves all three. Most caregivers should run two — a blocker plus a companion — and we'll show you why below, including the categories where Tiina (our app) is not the right answer.

The honest read on each
- Cheap and effective for known-bad numbers (claims block 90%+ of repeat robocallers).
- Works on VoIP (internet-based) landlines too — rare and important if your parent still has one. Traditional copper landlines aren't supported.
- Quiet operation — calls go straight to voicemail, no theatrics.
- Clear privacy policy. US-based.
- Doesn't stop one-off social-engineering calls (the dangerous ones).
- No identity-theft features — it's a single-job app.
- iOS setup involves enabling Call Blocking in Settings, which trips up some parents on first install.
- Block coverage on par with or slightly above Nomorobo.
- "Answer Bots" hold scammers on the line wasting their time — entertaining, occasionally educational.
- Visual call-history dashboard caregivers like for peace-of-mind monitoring.
- $3 more per month than Nomorobo for substantially the same blocking quality.
- The prankback feature is a feature for you, not for your parent — most seniors don't want their phone "playing pranks."
- No landline support.
- Powerful caller-ID lookup against a community-built database.
- Free tier is genuinely usable.
- Caller ID here runs on a crowd-sourced database of names and numbers. The structural cost of that model: your parent's name and number can end up in it because someone else shared their data — no action by your parent required.
- Its data practices have drawn scrutiny abroad — Nigeria's data-protection agency opened a privacy inquiry into the service in 2019 (a Nigerian federal court later ruled in Truecaller's favor, in 2023), and in 2025 South Africa's Information Regulator opened an investigation into complaints that the app breaches that country's privacy law.
- To be fair to the current app: Apple's App Store rules bar apps from uploading your saved contacts, and Truecaller says its opt-in contact-sharing feature is not part of its app-store builds. Our hesitation is the database model itself — not a claim that today's iPhone app copies your parent's address book.
- Genuine all-in-one — robocall blocker plus credit monitoring plus dark-web scanning plus password manager plus VPN.
- White-glove identity-theft recovery service if something does go wrong.
- Family-plan pricing makes the per-person math reasonable for 4-5 family members.
- $15-30/month for a single user is steep when most caregivers really only want #1 (call blocking).
- Bundled features mean a denser app and more "do you want to enable X?" prompts — friction for older users.
- Not voice-first; your parent needs to navigate a dashboard to do anything.
- Voice-first — your parent opens the app and talks. No menus, no buttons, no PINs.
- Stops the second-call problem: most parents who got scammed once don't tell anyone, and get scammed again because they have no calm voice to call. Tiina is that calm voice.
- Helps with the social-engineering calls that no call blocker can stop — voice-cloned grandparent scams, IRS imposter calls, fresh Medicare scripts.
- Works after the call ends — when shame and confusion are highest and a child isn't reachable.
- Doesn't block calls. If your parent never picks up unknown numbers, you don't need Tiina — you need Nomorobo.
- iOS only as of May 2026.
- $24.99/month is more than any single-purpose blocker. We're a different category, but if you're price-shopping a blocker, we're not the answer.
- Requires your parent to actually open the app after a call — works best when set up with the parent, not for them.
Run two apps. Total: $26.98/month.
Nomorobo + Tiina. Nomorobo catches the calls from known-bad numbers — the bulk of the robocall volume — before the phone even rings. Tiina handles the ones that get through — the social-engineering calls a blocker can't see — and the moment of doubt after.
If your parent already has identity-theft monitoring through their bank or a credit card, skip Aura. If they don't and they're a high-target profile (recent widow, recent inheritance, public records), Aura's bundle starts to make sense. We'd skip Truecaller — not because it doesn't work, but because a crowd-sourced caller-ID database isn't a trade we'd make with a senior's number and social graph.
The honest version: there's no single app that solves "phone scams targeting seniors." A blocker plus an after-call calm voice is the closest thing.
A scammer counts on no one being there to ask. Tiina is — a companion on the phone who'll talk through any "urgent" call, calmly, before your parent does anything they can't undo.
Frequently asked
What this sounds like with Tiina in the room
Sunday afternoon. Your mom's iPhone rings — Nomorobo silenced four unknown calls this week before the phone even buzzed. But one got through: a man saying he was from Apple about her iCloud. She hung up. She opens Tiina. "He said my iCloud was compromised. I hung up. Did I do the right thing?" Tiina answers. Yes — Apple doesn't call you about iCloud. Walks her through how to verify her account is fine in the Settings app. Doesn't sell her the next defense. Just confirms: the call was a scam, you handled it, here's how to check.
Nomorobo blocks the obvious calls. Tiina handles the one that gets through.
No filter catches every scammer — and the ones that slip past are the ones built to sound real. When that call lands, she needs somewhere to take the story before she takes the action.
