Latest updates
3.28.0
+ Every text goes out one at a time, from your own phone number, so it lands like a normal text from you — not a group blast, not a strange 5-digit number, not an email pretending to be a text. Replies come back to you privately, like any other conversation. Most mass-texting services simply cannot do this, because they don't send from your phone — we do.
+ You now have room to write. Pull the message box up and it fills the whole screen, like writing a letter instead of squinting at three lines. Slide it back down to check what people said.
+ Putting each person's first name in your message is now one tap. The buttons sit right above your keyboard: tap "first name," and every single person gets a message with their own name in it — "Hi Sarah," "Hi Marcus," "Hi Emily" — automatically. Sending 50 personal-feeling texts takes the same effort as sending one.
+ Adding people no longer interrupts your writing. Type a name or number right where it says "To" — even someone brand new — and they're added and saved as a contact while you keep writing. Picked a group first? Everyone you add joins it — the app asks just once, and the group's name stays right there with each new person beside it.
+ Fix a contact the moment you notice the mistake. Wrong spelling? Old number? Tap the pencil on their card and correct it right there — and it fixes it in your phone's contact book too.
+ Group lists take care of themselves. Swipe to remove someone, type a name to add someone, put one person into several groups at once. Added the wrong people? Shake your phone and choose who stays.
+ Writing to just one person is now instant. Their actual name appears as you type, and the message sends immediately — no extra confirmation screen for a single text.
+ Wrote something good? Keep it. Save any message as a template and the names automatically become fill-in-the-blanks, ready for the next group.
+ You cannot lose a message anymore. Leave the screen any time — your writing saves itself as a draft, and a small note tells you exactly where to find it.
