Weaponize it
Best spam call blocker apps — an honest comparison
Yes, we make one of these, so read this with that in mind. We'll make it easy to check our work: here's what each option genuinely does well, including our competitors.
The honest table
| Option | Best at | Weak spot | Price |
|---|---|---|---|
| Carrier apps (ActiveArmor, Call Filter, Scam Shield) | Network-level blocking of known scam numbers before your phone rings — the free baseline everyone should enable (setup guides) | Reputation-only; fresh spoofed numbers sail through; gray areas just get labels | Free |
| Truecaller | Caller ID — the biggest community number database in the world; excellent at telling you who's calling | Identifying isn't stopping; free tier carries ads; the database only knows already-reported numbers | Free w/ ads; paid tiers |
| Robokiller | Aggressive blocking plus Answer Bots that play prerecorded loops at spammers — they pioneered making spam fun | Bots are loops, not conversations — most scammers bail in seconds; aggressive blocking can eat legit calls | Subscription (~$5/mo range) |
| Nomorobo | Simple, cheap, effective on classic robocalls; the landline OG | Light on fresh-number and text protection; no screening layer | ~$2/mo mobile; free landline |
| Google Call Screen | Free conversational screening on Pixels — genuinely catches fresh numbers | Pixel-only; robotic voice makes real humans hang up; identified spam just... ends | Free (Pixel) |
| Spam Slayer | Conversational screening with a human-sounding voice (catches fresh numbers), plus the crew: spam calls become held calls, transcripts, and shareable clips | Newest entrant — our crowd database is the youngest on this list, growing with every crew call; the crew costs $4.99/mo | Free tier; Crew $4.99/mo |
How to actually choose
- Want zero effort and zero dollars? Enable your carrier app and phone settings today. That's the floor, and it's decent.
- Mostly want to know who's calling? Truecaller's database is the best in the business at that job.
- Want spam calls to just die quietly? Nomorobo or an aggressive carrier setting.
- Want fresh spoofed numbers caught too? You need conversational screening — Call Screen on a Pixel, or Spam Slayer anywhere.
- Want the scammer to regret dialing? That's the category we built. Answer bots gesture at it; a crew that actually converses is the difference between a twenty-second bail and a twenty-two minute Wilma call.
