Nuumara

Nuumara is a caller ID app designed to protect you from all the spam calls you receive on your Android device. The app is able to identify a wide variety of incoming numbers thanks to its extensive database. You can also manually add other phone numbers to prevent them from calling you, making it so that your device doesn't even ring.

In order to function properly, Nuumara needs permission to overlay on top of other apps, which is a very sensitive permission. However, without it, it won't be able to recognize calls, so you'll have to grant this permission if you want to use the app.

If you have doubts about the origin of a specific phone number, Nuumara allows you to search its database. You can search for free for 30 minutes, with an ad displayed after each search query. If you want to avoid the time limit or the ads, all you have to do is pay for the premium subscription. You can also sync your call history, after which the app can analyze all the numbers that appear there.

So, if you're looking for an interesting spam number identification app, downloading the Nuumara APK is a great choice.
