This simple app lets you restrict incoming calls to your contact list only.

There are lots and lots of apps similar to this. Here are some features that might make this app the correct fit for you:

* Easy to set up. App will show you the simple steps to enable it.
* No complicated allow and deny lists. It blocks non-contacts and that's it.
* Simple settings to choose exactly how calls get blocked.
* Allow non-contacts to call for a short time, when you need to.
* Simple log screen showing which incoming calls were allowed or blocked.
* Free and advert-free and always will be.

If you're a person who doesn't answer the phone unless you are either expecting a call or can see who is calling, then this might be a useful app for you.

If you're a person who receives mainly spam and phishing calls from the numbers you don't recognise, then this might be a useful app for you.

Your privacy is important. This app works entirely on-device and does not send any of your personal information or call logs anywhere.

Bonus tip: you can select phone numbers from the log text and use the "share" function to your device's browser and search engine if you want to easily find information about who unidentified callers are.
