Spam SMS Blocker: Filtr

Quiet your inbox, keep your privacy.

If your messages are buried under delivery scams, fake bank alerts and loan spam, Filtr is built for you. It is an on device SMS filter that quietly sends junk texts to the right folder before they ever interrupt you. Filtr uses Apple's message filter system, which means every decision happens on your iPhone: no message you receive is ever sent to a server, read by us, or shared with anyone. It is made for people who are tired of spam but unwilling to trade their privacy for a clean inbox.

Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a one-week free trial; you may cancel anytime during the trial to avoid being charged.

Set Filtr as your SMS filter once and it works in the background from then on. Incoming texts from unknown senders are checked against your rules and sorted into the junk folder automatically, so promotions, scams and one time spam stop landing next to messages that matter. You build the logic with simple, readable rules: block by keyword, by sender pattern, by links, or by number prefix, and allow the senders you trust so a real code or a family text always comes through. Ready made preset packs cover the most common spam in your region, so protection starts strong on day one.

A clear activity view shows what Filtr has caught, so you stay in control instead of wondering what got filtered. You can review blocked messages, recover anything caught by mistake with a tap, and tune a rule in seconds. Custom lists let you keep a personal blocklist and allowlist, and because the matching runs locally, filtering keeps working with no signal, no account and no setup beyond a one time toggle in Settings. There are no ads, no tracking and no inbox scanning, ever.

Filtr fits real life, where spam never stops evolving. The day a new scam wave hits your region, add a keyword or a number prefix and it is gone from then on. Keep a code from your bank coming through while a lookalike sender is blocked, let a delivery update reach you while fake tracking links go to junk, and review a week of caught messages to see exactly what you have been spared. Because nothing leaves the phone, it protects an elderly parent, a child's first phone or your own number without ever building a profile of who texts you.

Filtr ships in 39 languages with full VoiceOver and Dynamic Type, and it never asks for your contacts or your message history. The whole point is a calmer phone that still belongs to you: spam in the junk folder, real messages where they should be, and your private texts staying private. It works as a spam blocker, a scam filter, a junk text sorter and a quiet layer over the Messages app you already use.
