Spam Call Blocker: Call Management Tool

Spam Call Blocker is a phone and SMS utility by Adam that manages and blocks unwanted incoming calls. The app addresses the daily frustration of nuisance calls by allowing you to create a blocked list while also maintaining a whitelist of trusted contacts who can always get through. It stands out by using web scraping to check unknown numbers against real-time data from popular Spanish spam-detection websites, helping you decide whether to answer. All your settings and lists are stored locally, and you can export or import your configuration for easy backup or transfer between devices.

Key features

• Block and unblock specific phone numbers with a simple tap.
• Maintain a whitelist of approved contacts who can always reach you.
• Automatically look up unknown numbers using real-time web scraping from listaspam.com and responderono.es.
• Export your full configuration, including blacklists and whitelists, to a file for backup or transfer.
• Import previously saved settings to quickly set up the app on a new device or after a reset.
• Stores all your preferences and lists locally on the device, with internet access used solely for number lookups.

How to install

1. Tap the download button on this page to get the APK file, which is about 3 MB in size.
2. When prompted by Android, allow your browser or file manager to install apps by enabling the 'Install unknown apps' setting.
3. Open the downloaded APK file from your notifications or file manager.
4. Tap 'Install' and wait for the process to finish.
5. Open the app and begin configuring your block and allow lists. The app requires Android 10 or higher.

This app is ideal for beginners in Spain or those who frequently receive calls from Spanish numbers, as its core blocking intelligence relies on two Spanish-language spam databases. It suits privacy-conscious users who want a transparent, ad-free, and open-source tool without paying for a premium caller ID service.

For best results, when you receive a call from an unknown number that isn't automatically flagged, you can manually add it to your block list. Remember to regularly export your settings if you plan to switch devices or perform a factory reset.

Overall, Spam Call Blocker is a straightforward choice for anyone seeking a no-cost, open-source solution to reduce nuisance calls. Its reliance on Spanish-language spam databases and local-only data storage makes it a privacy-conscious, albeit region-specific, utility.
