Read full description

Fast Message is a powerful messaging toolkit that lets you send messages to any phone number — across WhatsApp, Telegram, Signal, and SMS — without saving it to your contacts. Built for business professionals, delivery coordinators, online sellers, and travelers who communicate with dozens of numbers daily, Fast Message goes far beyond a simple dialer. It's a full-featured messaging hub with a built-in contact book, analytics dashboard, business card scanner, and more. MULTI-PLATFORM MESSAGING Send messages via WhatsApp, Telegram, Signal, or SMS — all from one screen. Switch between platforms with a single tap. No need to install separate shortcut apps for each service. BUILT-IN CONTACT BOOK & MINI-CRM Save contacts directly inside the app with custom groups (Client, Delivery, Vendor, Personal), tags, notes, and star your favorites. Search and filter instantly. Track how often you message each contact. Unlike your phone's contact list, this CRM is purpose-built for quick messaging — no clutter, no syncing your entire address book. BUSINESS CARD SCANNER Point your camera at any business card and automatically extract the name, phone number, email, and company. Powered by Apple's on-device Vision framework — no data leaves your phone. Scanned contacts are saved directly to your contact book, ready to message. MESSAGE ANALYTICS DASHBOARD See your messaging activity at a glance: total messages sent, weekly trends, daily averages, and sending streaks. View a 14-day bar chart of your activity, see which platforms you use most, and discover your busiest hours and days. Your top contacted numbers are ranked so you can identify your most important connections. MESSAGE TEMPLATES Create, organize, and reuse message templates across categories — Work, Personal, and Emergency. Stop retyping the same messages. One tap fills your composer with a saved template. SCHEDULED MESSAGES Plan messages in advance. Set a date and time, and receive a notification reminding you to send it when the moment arrives. QR CODE GENERATOR Create shareable "Tap to Message Me" QR codes with your phone number and a pre-filled message. Perfect for shops, business cards, and flyers. Save QR codes as images or PDFs. Supports multiple QR types: Text, WiFi, Phone, Email, URL, and SMS. SMART FEATURES - Scan phone numbers from images using your camera (OCR) - Clipboard detection: prompts when a phone number is copied - Voice-to-text message composition - Share your live location or snap a photo while composing - Share Extension: select text or an image in any app, share to Fast Message, and the number is extracted automatically SIRI SHORTCUTS "Hey Siri, send WhatsApp to [number] using Fast Message" — hands-free messaging with App Intents support. iCLOUD SYNC Keep your contacts and templates synchronized across all your Apple devices. Enable iCloud sync in Settings and your data stays up to date everywhere. GLOBAL SUPPORT Works with international dialing codes and phone number formats from every country. Default country code is auto-detected. PRIVACY FIRST All data is stored locally on your device. No accounts, no servers, no tracking. Business card scanning uses Apple's on-device OCR — nothing is uploaded. Your messaging data never leaves your phone. No ads. No subscriptions. Just fast messaging.
