“Ethiopia natural. 40 bags. Go.”
How it works

Three steps. Zero doomscroll.

01
Create a hashtag
Short, memorable, yours. Open to the world or closed behind an invite code.
#pizza_night
02
People subscribe
From your profile, a shared link, or a QR on your door. Per-topic, not per-person.
#closing_early
03
Ring it
One tap, optional two-line note. Every subscribed phone gets one push. Done.

Be in the know, without the noise.

For businesses & creators

Reach 100% of your subscribers. Every time.

No algorithm deciding who sees your post. If someone subscribed to #closing_early, they get #closing_early. A gym, a coffee roaster, a food truck — one tap, every phone.

Per-topic subscriptions — followers pick exactly what they want pinged about
Subscribers control mute hours and sound; you never spam anyone
A QR code on your counter is your entire growth strategy
open
Public topics anyone can find and follow. Your storefront bell — #deal_alert, #iam_live.
closed
Invite-only — shown as locked on your profile, or fully invisible if you prefer. The group chat minus the chat — #five_a_side rings when it’s game time.

Your hashtag is waiting.
Someone else wants it.
