Stop SPAM calls and get your peace back.

Callthentic prevents unwanted calls to your iPhone. It compliments the new iOS 13 "Silence Unknown Calls" feature.

Our unique system provides multiple levels of protection against spam calls. Callers not in your phone’s contact list are presented a key press request that must be entered for the call to complete. This prevents unwanted robo dialer and spam calls without having to deal with a voicemail box full of junk messages. If the caller exists in your contacts, the call is sent through normally. Your contacts won’t know you are using the best spam call protection app available.

For any calls you do not answer, we provide voicemail with automatic transcription. You can access the voicemail within our app, and you will also receive a text message of the transcription.

We only manage your inbound calls, as your outbound calls will be made from your phone as normal.

The app can quickly be disabled or enabled easily on the settings screen. This app does require a data connection (LTE or Wifi) to process non-contact calls.

The app requires call forwarding from your phone. Depending on your iOS version, the call forwarding may be either conditional or unconditional. In iOS12, our app uses unconditional forwarding and handles all inbound calls due to the call feature limitations.

We do not rely on the typical methods other apps have used to prevent unwanted spam calls such as a blacklist or whitelist. That method no longer works because numbers change constantly. We simply divert calls that aren't in your contacts.

Currently supports users on AT&T, Verizon, T-Mobile, and Sprint in the United States. Now with support for Rogers and Telus users in Canada. Requires iOS 12 and higher.

Voicemail won’t change

I updated my voicemail and changed it back later. Although I later removed call forwarding, deleted the app, and changed voicemail thorough my native settings, I still hear the Callthentic voicemail greeting I made for my contacts.... how do I get my voicemail back?

Edit: Pretty fast turn around from the developer to fix my problem. Feels like 5 star service and the app does what it says, but UI could use a little loving.

Developer Response ,

We apologize for the issue you had with the disable call forwarding feature. This was investigated and was found to be a coding defect. We will be updating that in the next release. Thank you for the feedback and the time to update your review.

Callthentic gave me my privacy back!

I cannot recommend this app enough! Prior to installing it, I was plagued by at least 20 calls a week from call centers asking me if I was ”the business owner” and as a result, I would ignore all calls not in my contacts, including legitimate ones!

IOS 13 had the option to automatically silence these calls, but I could never bring myself to turn it on out of fear I would miss something important, but Callthentic gives all callers the phone equivalent of a CAPTCHA, which allows them to leave a message and then texts a transcription to you!

I can say with confidence that this app has given me at least an hours worth of productivity back every day. I don't care if I sound like a shill. They have earned my endorsement!

Developer Response ,

Your descriptive review is much appreciated. You have perfectly described how this app adds value to the iOS 13 feature. Without Callthentic, unknown calls have a dead end destination. Now you still have a way to receive a legitimate call which wasn’t in your contacts.

Hope you continue to get your time back with us!
