About this app

Nize is an easy-to-use caller ID reader and free spam call blocker for Android, which enables you to get contact info on who’s calling you, block robocalls, screen calls from blocklisted numbers, customize the app UI based on your preferences by switching between the Light & Dark theme, and more.


- Utilize “Who called me” functionality
- Trap call spam using the smart spam shield & robocall blocker
- Benefit from using the easy-to-use call screener
- Get offline access to a global call detector database
- Switch between the light and dark app themes

Leveraging robust reverse lookup features, Nize enables you to identify an unknown caller ID and determine a real caller name fast & easy, even if you missed the call itself.

Using the app, you can get instant alerts, identify and easily block spam, robocalls, ping calls, aggressive advertising, annoying survey requests, harassment calls, etc.

It’s also possible to create custom call block lists based on your call log history. In such a way, you won’t even need to bother with getting unwanted calls, since the in-app screener will block numbers from the created list automatically.

More importantly, Nize enables you to identify unknown phone numbers even if you're offline - in a massive database, available for your reverse phone lookup free.

And last but not least, you can get your spam call blocker free with Nize, hence accessing its advanced call protect features without paying a dime.

Nize requires the following app permissions:

* Call log - enables app access to your call log and a caller's phone number.
* Phone - allows identifying incoming and outgoing calls.
* Contacts - enables the app to determine, if you already know a caller.

Note! Nize does NOT collect, store, or disclose your Phone contact list to any third parties!
* Overlay (run over other apps) - enables the display of an incoming caller ID on the call screen.

How to get started?

Nize enables you to configure a wide array of settings the first time you’re using the app. Let’s see how it works.

1. Open Nize.
2. Sign up using your phone number.*
*An SMS with a 6-digit verification will be sent on your device.
3. Enter the code you received to verify your phone number.
4. Grant the required permissions to the app.
5. Download the up-to-date offline database for easier phone number lookup, whenever you like, even with no Internet connection.
6. Configure stability and usability features:
* Disable battery optimization - switch on the feature to prevent Nize to ensure the proper caller identification.
* Block calls from low-rated numbers - switch on this feature to stop spam calls from phone numbers with a two-star rating or less.
7. Personalize app settings (e.g. switch to the Dark theme), if needed.

Seems pretty good to use, updates to the database though don't tell you when they're done installing.

Hi, Thank you for your comment, this was done on purpose in order to not bother the user. However, you can check the download status in the app menu - settings.

Only option I wish was added would be to auto-block callers with low ratings, but otherwise great app!

Another useful app by Cube Apps. Thanks to developers. Newly using it. It's working well so far. An important feature to add is, Contacts List showing contacts' photos, from automatic upload, by automatic sync to their facebook, and/or other social media profiles. This function, if added, will make this app a more user-friendly and developer-beneficial dial-up app.

Hello, thank you very much for your review. Actually, the photos must be displayed in the call logs inside the app. Can you describe your suggestions in more details?
