Meow Messenger

Meow at me! That is the new way to say "text me". Meow Messenger is for the very closest people: family, the ones you love, a couple of best friends. That is the whole list. No coworkers, no channels, no strangers selling you a garage. PAWS INSTEAD OF TICKS One paw means the meow is on its way. Two mean it landed on the other phone. Pink means it was read — and they only turn pink when the chat was really opened. The paws are honest. NOTIFICATIONS THAT ACTUALLY MEOW A real meow instead of a ping. An important one gets through even in Do Not Disturb, because the people closest to you outrank a focus mode. REQUESTS THAT DO NOT SINK "Grab some milk on your way" arrives as a card with an Accept button, not as one more line in the stream. If it stays undone, a very polite cat will bring it up again. And every request you complete makes your cat kindness stronger — twenty ranks, from your first favour to a lifetime of them. NOT ONE MEOW GETS LOST Subway, elevator, a cabin with no signal — the message waits for the network and arrives. Delivery is a cult around here. VOICE NOTES, PHOTOS, REACTIONS A seven-minute voice note from your best friend? Listen at 3x. Photos go out as originals, without being squashed. A heart is one tap away. CALLS, WITH VOICE AND VIDEO They run straight between devices. We do not record them. GROUPS FOR PEOPLE WHO BELONG TOGETHER Family, the two of you, the cat's own fan club. WHAT YOU WILL NEVER FIND HERE No ads. No channels shouting about discounts. No strangers opening with "Hello, you have won". No work thread called URGENT_edits_FINAL_2. Free. Sign in with Apple or with Google, and meow at your people.
