Spam SMS Blocker: Filtr
Filter spam texts on your iPhone, privately
Filtr sorts junk texts from unknown senders into the right folder before they interrupt you. It uses Apple's built-in message filter system, so every decision is made on your iPhone with rules you control. No message is ever sent to a server.
What it does
On-device filtering
Texts from unknown senders are checked on your iPhone and sorted into Junk, Promotions or Transactions.
Your own rules
Block by keyword or sender, add regex rules and keep a whitelist of trusted senders.
Ready-made presets
Start from keyword libraries for common spam in different countries and languages.
Filter dashboard
See recently filtered messages, mark mistakes and follow simple statistics.
Home Screen widget
A widget shows how many messages Filtr has blocked.
Rules backup
Export your rules, blocked senders and whitelist and import them later.
