Description

Been using Robokiller – Spam Call Blocker for a couple months now. It’s basically an app that blocks spam calls and texts so you only get the important ones. Pretty solid if you’re sick of all those annoying robocalls and scammers.

Here’s what you do: you can add numbers to a blocklist, and Robokiller’s got this audio fingerprinting tech that automatically blocks any call that matches known spam. And there’s also a feature where you can set it as your default SMS app and it’ll block 99% of spam texts too. Took me a while to figure that one out but it’s super useful.

Look, if you’re constantly getting bombarded with spam and just want some peace and quiet, you’ll probably like this. It’s not perfect – the blocklist can be a pain to manage sometimes – but overall it does the job. Worth checking out.

Editor Opinion

So here's my honest take on Robokiller - Spam Call Blocker. I've tested a bunch of spam blocking apps and this one's one of the better ones. The AI-powered call and text filtering works pretty well, and I like how you can customize your blocklist. But it can get annoying having to manage that list, and the free version has some ads that get old after a while. Still, if you want an effective way to stop spam without a ton of hassle, Robokiller is a solid choice.
