Ringwall: Spam Call Blocker

Ringwall is a caller ID and spam call blocker that helps you see who is calling before you pick up, check unknown numbers, and keep unwanted callers out of your day.

WHAT RINGWALL DOES
• Caller ID on incoming calls: see the name of anyone saved in your contacts, plus a clear risk label for numbers that match the app's spam database.
• Spam call warning: when a number looks risky, the call screen shows a "Spam risk" warning so you can decide whether to answer or decline.
• Number tracker: type any phone number to see its risk level, category and how many community reports it has.
• Call blocker: add numbers to your block list, or block a number straight from your call history. Calls from blocked numbers are rejected automatically once Ringwall is your default phone app.
• Call history: your recent calls with All, Missed, Incoming and Outgoing filters, plus Blocked and risk badges so spam stands out.
• Contacts and dialer: search and add contacts, see recent activity for a contact and place calls from the built-in dialpad.
• Unseen messages (optional): if you grant notification access, Ringwall lists message previews from supported chat apps in one place, so you can glance at a preview without opening the chat. Opening the chat app itself may still mark messages as read.
• 15 languages, from English and Spanish to Arabic, Hindi, Japanese and Vietnamese.

PRIVATE BY DESIGN
Spam lookups use a database bundled inside the app, so the numbers you look up are not sent to a server to be checked. Your contacts, call history, blocked numbers and message previews are processed on your device. No account or sign-in is needed.

SET RINGWALL AS YOUR PHONE APP TO BLOCK CALLS
Android only lets an app reject incoming calls automatically when it is your default phone (dialer) app. Ringwall asks you to choose it in the setup screen or from the banner in the Block tab, and you can switch back to another phone app at any time in Android Settings.

PERMISSIONS, EXPLAINED
Ringwall asks for each permission only for the feature that needs it, and you can change them in Android Settings at any time.
• Phone and call screening: Ringwall uses the Android phone state, call screening and in-call services to see the number of an incoming call, show caller ID and the spam warning, and reject calls from numbers you blocked. Placing and answering calls from the dialpad and call screen uses the call-placing and call-answering permissions.
• Call log: Ringwall reads your call log to show your recent calls and to let you block or save a number from that list.
• Contacts: Ringwall reads your contacts to show names on calls and in the Contacts tab, and writes to them only when you ask it to save or edit a contact.
• Notification access (optional): used only by the Unseen tab. Ringwall reads notifications from supported messaging apps to show their preview text. Previews stay on your device and you can turn access off in Android Settings at any time.
• Notifications and full-screen call screen: used to alert you to incoming calls and to show the call screen when your phone is locked.

GOOD TO KNOW
• Spam labels come from a community-sourced database (mostly US numbers) and simple on-device checks. Labels can be incomplete, outdated or wrong, and Ringwall cannot identify or block every unwanted call.
• Ringwall is not meant for emergency situations. Do not rely on it to place or receive emergency calls.
• Ringwall is not affiliated with, endorsed by or sponsored by any phone carrier or messaging service. The Unseen tab only reads notification previews that the other app has already shown.
• Ringwall is free to use and contains ads. See the Privacy Policy for details on advertising and analytics partners.
