New: AI Bodyguard answers your calls, speaks Czech with the caller, and sends you a summary of what they wanted. Top-rated Czech call-blocking app. First week free.
You know the moment: an unknown Czech number is calling. Your courier? A telemarketer? Another "investment opportunity" — in a language you barely understand?
Zvednout to? (Czech for "Answer it?") has been protecting phones from spam and scam calls since 2016. It knows 220,000+ Czech numbers, labels or blocks unwanted callers — and when you can't answer, AI Bodyguard handles the call for you.

Your bodyguard got new gear. And we stopped making a few things harder than they need to be.
• Subscription expired? You still get into the app. Caller ID and blocking show as inactive, and one tap brings them back.
• Used up your screened-call limit? Upgrade to a bigger plan (50 or 80 calls) right in the app, no support email needed.
• Unread screened calls now show as a badge on the app icon. It clears once you've actually looked at them.
• Deleting the app? Long-press its icon and your bodyguard reminds you to turn off screening first. Otherwise he keeps answering your calls, and you can no longer get to them.
• Minor improvements and bug fixes.
4.9.3 Oct 6
Your bodyguard straightened his tie and cleared two spots where you could get stuck.
• Turning off call screening no longer gets stuck on the "Disable forwarding" screen. After you dial the carrier code, the Done button lets you move on.
• On iOS 27, the app now offers the manual code right away when you set up or disable forwarding, even right after a system update. Auto-dialing simply doesn't work there.
• Minor improvements and bug fixes.
4.9.2 Sep 18
Your sharp-tongued bodyguard just got sharper. Here's what's new:
• Out of call-screening credit? Instead of a note about a subscription you already have, you now see when your credit resets. And one tap on the new button writes to us about a bigger limit.
• On an invoice-billed plan? The app now recognises it on its own. Call screening is unlocked, and the Subscription section shows your plan name and renewal date.
From recent updates:
• Screened calls show names from your contacts, not just bare numbers.
• We rebuilt the AI Bodyguard setup from scratch. It clearly explains what happens before you begin.
• Rated a call summary? You can now tell us why. Every word helps us put annoying callers in their place.
• Minor improvements and bug fixes.
4.9.1 Sep 15
The bodyguard hates job interviews, but he'll make an exception for you. Free demo call.
• Call screening has a new welcome screen: see what the bodyguard actually does, and try a free demo call – ring yourself and hear him in action.
• Screened calls now show names from your contacts instead of bare numbers. Grant contacts access with a single button, right in the call list.
• After you rate a call summary with a thumbs up or down, you can add a quick note on why. Optional, but it makes our summaries better.
• Minor improvements and bug fixes.
4.8.8 Aug 31
Signing in should never be a guessing game. This update takes care of the bumps at the front door.
• We've improved the reliability of signing in with your phone number – the verification code now arrives as it should.
• Sign in with a different method than the one you registered with, and the app now tells you exactly which door to use.
• Phone number stuck with an old account? No longer a roadblock – sign-in sorts it out on its own.
• Fixed a bug that made activating call screening harder for some of our long-time subscribers.
From recent updates:
• We've added company numbers to the database – so you can identify many more callers, not just the annoying ones.
• Minor improvements and bug fixes.

Another round of updates to help you deal with annoying calls like a pro.
• Our database just grew by 160,000 company numbers — that's over 220,000 numbers we keep an eye on. You'll know right away when it's your bank, a courier, or another business calling.
• Fixed a bug where the app could forget to cancel your original subscription when activating a new one. Not on our watch.
4.6.1 Aug 14
Who's calling? Now you'll know, even when the number isn't in your contacts.
• Calls from businesses now show up under the company's name – the restaurant, the garage, your doctor's office, the courier. We added over 100,000 business numbers to the database to make it happen, so you can stop guessing who's on the other end.

4.5.1 Aug 4
Your bodyguard now comes in two sizes. Pick yours — or let us recommend one.
• Two packages to choose from: “Peace of Mind” flags and blocks nuisance calls and deals with scam texts, while “I Know Why” adds a bodyguard who screens unknown numbers and finds out who's calling and why.
• Right at first launch we ask a few quick questions and recommend the package that fits you best.
• We show you live how screening unknown numbers works — and you decide there and then whether you want it.
• Already signed in? We won't nag you to do it again, onboarding just skips it.
• Polished buttons and copy so everything hangs together.
• Minor improvements and bug fixes.
4.5.0 Jul 30
