Online Booking (*)
Clever Dialer can use telephone numbers of contacts to determine whether a restaurant offers online reservations or whether you can book an appointment online with a doctor or hairdresser.
These numbers are not stored outside the mobile phone.
(*) Currently, only available in selected countries.

In addition, we display contacts in the speed dial and contacts list of the app.

With Clever Dialer spam callers don't stand a chance. Incoming calls are being checked against our extensive spam caller database. The Clever Dialer community helps us staying on top of things. Every user can report spam calls, so even numbers that spam only very recently are included.

Want to block your boss or ex spouse? With Clever Dialer you can block any number you want and get your privacy back.

Unknown numbers can mean trouble. That’s why spam recognition is Clever Dialer’s most important feature. Because if an unknown caller wants to annoy you, we’ll find out who it is. By working with various partners, Clever Dialer can identify telephone numbers as spam and block them – making it the ideal ad blocker. Someone ringing from a call center can be identified for example, and the app can block the associated phone numbers. This works, even if you have no internet connection because all spam numbers are stored in your app and updated as soon as you are online. This way you are protected even if you are offline.

With the call blocker, you don’t have to bother with unknown numbers from call centers – identify spam and simply block the numbers – it makes life so much easier :)

It’s also possible to review the caller straight after the call. If you feel harassed, you can give the caller a bad review and also leave a comment directly. Everybody else benefits too because this means that the app warns even more effectively against annoying spam callers. Naturally, you can give a positive review and comments after a call, too.

Number recognition not only shows you unknown spam numbers but also allows you to block unknown callers. Identify calls and add the numbers to the Blocked list – then there’s no chance that those numbers can ever reach you again. Your telephone won’t ring if you receive a call from someone on the Blocked list – because the app recognizes the caller and instantly blocks the call.
Your telephone won’t ring if you receive a call from someone on the Blocked list – because the app recognizes the caller and instantly blocks the call.

We guarantee you that we treat your contact details responsibly. We will never upload your data or disclose them in any other way.

Doesn't block calls until the number is entered into the block list. That's not really a big deal though. There are two issues: First, even though a call might be blocked from ringing, the "blocked" caller can still leave a voice mail - not sure that qualifies as blocking a number. Second, and even more annoying, is that if I'm on a call and this app blocks another caller, my phone call is always disconnected. Not cool guys, you really need to fix this app.

Hi, thank you for your feedback. I see that you are using a quite old version of Clever Dialer. We improved blocking significantly in the last versions. I would recommend that you update to our latest version. If you still have any problems, please feel free to contact our support at

Mostly good. Third one I tried that actually worked. blocked numbers can still leave a voicemail. and they still show up on my history! how can i turn both of these off please?? is there also a way to have my number go straight to voicemail instead of ringing? i essentially want the same experience as the basic android call blocking feature. 1. it sends them straight to voicemail and 2. never shows up in my history. almost like it never happened. Thank you!

Hi Cristian, thank you for your feedback. The blocked calls show up in your call history to make you aware of them. We are currently working on a solution to remove blocked calls from the call log. As for the redirection to voice mail, it is more tricky, because IMHO it depends on the phone provider what happens.

So far so good. I appreciate the lack of clutter of ads that seem to be the norm for other call blockers I've used. The ads are non-intrusive and the app is user-friendly. Thanks to the app developer that assures users that the app will remain free. I deleted one that started out free and was doing a good job but then started charging a fee out of the blue and then threw in annoying junk to try to force me to opt for its paid version. THX & keep up the good work with this NON-bait & switch app!
