iPhone · calls and messages
Most spam blockers tell you what they stop. This one also tells you what it misses.
Ringfence blocks known unwanted callers before your phone rings, labels the ones it is only suspicious of, and never claims a certainty it does not have. Your Allowed list always wins.
Impossible caller IDs, numbers we have observed calling, and the numbers you block yourself. The call never rings.
Lower-confidence signals — FTC complaints, community warnings. The call still rings, with context in Phone. A label is not an accusation.
Your Allowed list takes priority over every block Ringfence ships. iOS handles Contacts and your Phone blocks separately.
What it does, and what it cannot
Every spam blocker has the second column. Most leave it off the website.
Ringfence does
- Block known unwanted numbers before the phone rings, on-device.
- Filter spam and unknown-sender texts into the Messages junk folder.
- Identify unknown callers live, using Apple's encrypted lookup.
- Let you block a number yourself, without asking anyone to vote.
- Keep your Allowed list, your blocks and your contacts on your iPhone.
Ringfence cannot
- Block every unwanted call. No product can, and one that says so is selling something.
- Prove a labeled number is a scammer. Labels come from unverified complaints.
- See a call you answer before it forwards — it never reaches Ringfence.
- Tell you which SMS filter iOS selected. iOS publishes nothing an app can read.
- Read your messages. The filter runs on-device with no network permission.
Where your data goes
The protection list is downloaded to your iPhone and applied there. Ringfence does not receive a log of your calls. What leaves the device is a push token that carries no identity, a random install identifier, and only the numbers you deliberately choose to report.
