Web lookup plus app protection
iPhone app protection
Roblock is more than a lookup page
The web lookup helps you check a number before calling back. The iPhone app brings Roblock reports into iOS call blocking, SMS filtering, and the system report flows.
Filter spam texts from unknown senders
Enable Roblock in iPhone Messages settings to help route unwanted SMS messages away from your main inbox.
Report from Phone and Messages
After selecting Roblock for SMS/Call Reporting, you can report unwanted calls from Recents and messages from the Messages app when iOS offers the report action.
Choose identification or blocking
Some people want a visible warning before answering. Others prefer direct blocking. Roblock is designed around that choice.
More recent protection data
Premium access is positioned around the most recent block-list updates and neighbor spoofing protection in the iPhone app.

What Roblock protection is built from
Roblock combines a block-list database, community reports, FCC complaint signals, recent app updates, and iOS extensions. These are directional trust signals, not a promise that every unwanted call or text can be stopped.

Roblock supports unwanted call and message reporting paths from iOS.
Privacy positioning
Protection should not require exposing your contacts
Roblock's safest behavior is built around iOS extensions and minimal reporting. Keep report descriptions short, avoid private details, and use the app's optional on-device contact whitelist to reduce false positives for people you know.
Read Privacy PolicyContacts stay local for whitelisting
The app's contact-whitelist positioning is on-device, so contact details do not need to be uploaded to build that protection.
iOS handles call blocking
The Call Directory extension works from a local block list on the device. Incoming call handling is controlled by iOS.
Reports should avoid private content
When adding context to a report, do not include passwords, account details, private message text, addresses, or other sensitive information.
Scam intelligence
Track the patterns behind unwanted calls and texts
