Softonic flagged the summer job-scam wave at the end of June, and the pattern this year is familiar: an unfamiliar recruiter calls or texts about a remote role that pays unusually well, asks for your Social Security number or a bank login during onboarding, and disappears once you hand it over. The defence is layered. No single app catches every scam, but the right combination of caller-ID, company-verification, and identity-monitoring apps will flag most of the warning signs before you reply. We installed seven Android apps used by people who got burned and want to make sure it does not happen twice.
The picks below cover the three places job scams surface on a phone: the call or text that opens the conversation, the recruiter's company listing, and the data points a scammer asks you to share.
What to look for in a scam-detection toolkit
One app rarely covers the full attack surface. Five things matter when you assemble the toolkit:
- Caller-ID community size. Hiya and Truecaller win because millions of users have flagged the numbers that are calling you. A new app with no community data has nothing to surface.
- SMS scam detection. Job scams now arrive by text more than by call. The app needs to handle both channels.
- Company verification. The fake company you cannot find on LinkedIn or Glassdoor is the giveaway. The verification path matters as much as the call-blocker.
- Identity monitoring. The endgame is your personal data. A monitor that watches for breach exposure shortens the time between handover and damage control.
- Privacy posture. Caller-ID apps see your contact list. Read the data-handling page before you grant the permission.

The apps
1. Hiya: Best community-flagged caller ID
Hiya identifies incoming calls against a database fed by community reports, carrier feeds, and AT&T's call protection layer (Hiya powers a lot of the carrier "Suspected Spam" labels you already see). The free tier flags suspected scam calls with a red header, blocks the obviously-bad ones automatically, and surfaces a reverse-lookup tool so you can check a number after the fact. The Hiya Voicemail feature also transcribes incoming voicemails to text, which is the fastest way to triage a recruiter pitch.
Where it falls short: The Premium tier adds nuisance-call blocking and a sleeker UI, but most of the protection is in the free tier already. Hiya needs phone state permission, which is a real ask.
Pricing:
- Free: full caller ID, scam labelling, basic blocking
- Paid: Premium for nuisance-call blocking and voicemail transcription, from around $4 per month
Platforms: Android, iOS
Bottom line: The default pick if you already see carrier scam labels. The Hiya app surfaces more detail and a community reporting flow on top.
2. Truecaller: Best for the largest caller-ID database
Truecaller still has the broadest caller-ID database thanks to its long history in markets like India where flagging fake recruiter calls is daily behaviour. The community reports surface a name and a "Spam" label for unknown numbers, the search tool lets you reverse-lookup a number that messaged you, and the SMS protection layer auto-categorises incoming texts into Personal, Other, and Spam folders so a fake-recruiter text never sits in the same inbox as a real one.
Where it falls short: The free tier shows ads. The app's data-handling history has been criticised for uploading contact metadata. Read the privacy policy and opt out of the contacts upload during onboarding if that matters to you.
Pricing:
- Free: full caller ID, SMS triage, ad-supported
- Paid: Premium for ad-free and advanced spam blocking, from around $5 per month
Platforms: Android, iOS
Bottom line: The right pick if your job search includes Indian, MENA, or LATAM recruiters and you want the deepest community database.
3. Robokiller: Best aggressive call and text blocking
Robokiller goes further than the others by intercepting suspected scam calls with answer bots that waste the caller's time and feed the results back into the detection model. The Predictive Caller ID flags suspected scams with a confidence score, the SMS scam filter strips fake-recruiter texts out of the inbox, and the call recording feature captures evidence if you decide to file a complaint with the FTC. The product is paid after a short trial, which is the right pick for buyers who actually get a lot of scam calls.
Where it falls short: Paid only after the trial ends. Some users report the answer-bot occasionally engages legitimate cold callers, which can backfire if a recruiter was real.
Pricing:
- Free: 7-day trial
- Paid: from around $4 per month or $40 per year
Platforms: Android, iOS
Bottom line: The right pick for buyers in the US who get hammered by robocalls and want both call and text scams handled aggressively.
4. Should I Answer?: Best privacy-friendly caller ID
Should I Answer? is the open-source caller-ID app for buyers uncomfortable with the contact-upload models the big players use. The community database is built from user reports, the app does not require you to upload your contacts, and there is no advertising. It misses the deepest carrier integrations the paid players have, but it covers the obvious scam patterns and stays out of your private data.
Where it falls short: Smaller community database than Hiya or Truecaller, so fewer flagged numbers. UI is functional rather than polished.
Pricing:
- Free: full app, no ads
- Paid: optional donation
Platforms: Android
Bottom line: The privacy-first pick if you would rather have a smaller community database than upload your contact list.
5. Glassdoor: Best for verifying employers and salary ranges
Glassdoor is the company-side check. When a recruiter pitches you a role at a company you have not heard of, Glassdoor's company profile shows employee reviews, salary ranges, and a Trust Index that aggregates how legitimate the listing looks. The mobile app's search is fast, the salary comparison surfaces when the pitched offer is suspiciously high, and the recent-reviews timeline tells you whether the company has been the subject of scam complaints from past "hires."
Where it falls short: Glassdoor entries can be sparse for shell companies set up specifically to run scams. Some reviews are coloured by disgruntled ex-employees rather than scam victims.
Pricing:
- Free: full app, account required to read full reviews
- Paid: no consumer paid tier
Platforms: Android, iOS, web
Bottom line: The default verification step before responding to any unfamiliar recruiter.
6. LinkedIn: Best for verifying recruiter identity
LinkedIn is the recruiter-side check. The profile of the person reaching out tells you whether they have a real history at the company, whether their account is more than a month old, and whether their connection count is plausible. The Verified badge (when the recruiter has completed identity verification) is the strongest single signal that the person on the other end is who they claim to be. Cross-reference the recruiter's claimed company with the LinkedIn company page and check that the role they are pitching matches what the company actually advertises.
Where it falls short: The free tier still surfaces InMail spam from unverified accounts. Some scammers have refined fake profiles enough to look legitimate, so LinkedIn is one signal, not a complete answer.
Pricing:
- Free: profile, search, verification badge
- Paid: Premium tiers for InMail and recruiter-side tools, from around $40 per month
Platforms: Android, iOS, web
Bottom line: Run the recruiter through LinkedIn before responding. A fresh account with no shared connections at the claimed company is the loudest warning sign.
7. Trend Micro ID Security: Best for identity-leak monitoring
Trend Micro ID Security watches the dark web and breach feeds for your email, phone number, passwords, and a handful of identity fields. If a scam interaction leaks your details into a public breach, the app pushes a notification with the source and a suggested next step, which compresses the window between data handover and damage control. The free tier covers basic monitoring; the paid tier adds extra identity fields and account-recovery support.
Where it falls short: Monitoring is reactive by design. It tells you a breach happened, but it cannot undo the scam itself. Some users find the notification thresholds too noisy.
Pricing:
- Free: basic monitoring for email and a small set of identity fields
- Paid: from around $15 per year for extended monitoring
Platforms: Android, iOS
Bottom line: Add this last in the toolkit. It is the alarm that tells you a scam was successful, not the lock on the front door.
How to choose
Start with Hiya as the default caller-ID layer. The free tier covers most scam-call labelling without paying anyone.
Add Truecaller on top if your job search touches markets with large Truecaller user bases, especially India.
Add Robokiller if call and text scams are a daily nuisance and you would rather pay than triage by hand.
Pick Should I Answer? if you want caller ID without uploading your contacts to anyone.
Use Glassdoor the moment an unfamiliar company name comes up. A missing or thin profile is itself a signal.
Use LinkedIn to verify the recruiter individually. A fresh account, no shared connections at the claimed employer, and an unverified badge together mean walk away.
Add Trend Micro ID Security as the rear guard. If something slips through, you want to know within hours, not weeks.
FAQ
What is the best free app for spotting job scam calls?
Hiya covers the most ground for free. Should I Answer? is the strongest privacy-first free pick if you do not want to upload your contact list to a third party.
Can these apps block scam text messages too?
Hiya, Truecaller, and Robokiller all handle SMS scam filtering alongside calls. Should I Answer? is call-only. Most job scams now arrive by text first, so SMS coverage matters.
How do I know if a recruiter on LinkedIn is real?
Three signals together usually settle it: the account is older than a few months, the recruiter has shared connections at the claimed employer, and the role they pitch matches a public listing on the company's careers page. Missing one signal is fine; missing all three is the warning.
Are caller-ID apps safe to install?
They need access to phone state, contacts (some of them), and call screening. Read each app's privacy policy and prefer the apps that do not upload your contact list. Hiya, Should I Answer?, and the carrier-provided tools (AT&T Active Armor, T-Mobile Scam Shield, Verizon Call Filter) all have stronger postures on contact data than older caller-ID apps.
Will my carrier's free scam-blocker do the same thing?
Partly. US carriers ship free scam-blocker apps that share data with Hiya, First Orion, or TNS depending on the carrier. Hiya specifically powers some of the labelling. A dedicated app surfaces more detail and a reporting flow that the carrier apps hide.
