SMS Filter+ vs Secret Text

This is a safe, ef­fi­cient and pro­fes­sion­al SMS fil­ter. You can cus­tomize your own fil­ters to help you fil­ter spam and MMS mes­sages from un­known phone num­bers. What it does: Automatically classify your messages, filter junk messages, let you avoid being disturbed by spam during work, rest or when you are on your phone(such as gaming or reading). Privacy matters: All ver­i­fi­ca­tion ac­tiv­i­ties oc­cur in a closed and se­cured process pro­vid­ed by iOS, with­out the need to con­nect to the net­work through­out, and SMS Fil­ter+ will not read, col­lect or tag your mes­sages. Customize your filters: Filter your messages like a pro, support check phone numbers, text, containing multiple keywords, start/end with keywords, match with Regular Expression and other advanced features. How it works: When a mes­sage comes, SMS Fil­ter+ will al­ways go through your Allow, Transaction and Promotion filters. Once there is any filter made a match, messages automatically classified into the corresponding folder. If those filters can not make a match, then SMS Fil­ter+ will go through your Junk filters, mes­sage will be fil­tered if it matched as spam. Notifications & Badge If a message classified as Allow, Transaction and Promotion, you will still get notifications and unread badge on the Message app icon, if a message filtered as spam, you won’t get any notifications and there is no unread badge.

Secret Text is free to download and use for contact setup and handshake. It is a secure text translator, not a chat app. Encryption and decryption require an active 3-day free trial or Secret Text monthly/yearly auto-renewable subscription. It encrypts your plaintext into ciphertext that you can copy and paste through any messaging app (iMessage, WhatsApp, Telegram, WeChat, etc.), and decrypts ciphertext back into plaintext on the other end. How it works: 1. Add a contact and complete a guided handshake to establish an encrypted session 2. Start the official 3-day free trial or subscribe to unlock encryption/decryption 3. Type your message -> tap "Encrypt & Copy" -> paste the ciphertext into any messenger 4. Receive ciphertext -> tap "Paste & Decrypt" -> read the plaintext Security: - End-to-end encryption powered by Signal Protocol (X3DH + Double Ratchet) - AES-256-CBC with HMAC-SHA256 for every message - Per-message forward secrecy: compromising one key cannot decrypt past or future messages - Out-of-order message decryption support - Identity fingerprint verification through a trusted channel - All keys are generated and stored locally on your device Features: - Works with any messaging platform, no need to switch apps - Guided handshake wizard with step-by-step instructions - Contact management with session status at a glance - Monthly and yearly auto-renewable subscriptions with a 3-day free trial - Supports English, Simplified Chinese, and Traditional Chinese - Available on iOS and macOS with cross-platform session compatibility - Dark mode support Your messages stay private, no matter which messenger you use.
