  • Launching
  • SaaS, web + iOS + Android
  • chimepost.com
Chimepost homepage: "Post when your audience is listening", with a week planner of scheduled posts and suggested peak slots.

What it is

A social media scheduler for small teams. One draft becomes a native post on each network, scheduled for the hours your audience is actually around, from the web or the phone.

What was hard

Every network, its own rules
From Bluesky and Mastodon to Instagram, TikTok and YouTube, every network has its own API, limits and approval process.
Security that holds up
Login tokens never reach browser JavaScript. Refresh tokens rotate on every use, and a reused token revokes the whole session family.
One product, three apps
A web app and native iOS and Android apps share one API, one set of rules and one team workspace model.
Timing that learns
Chimepost learns each account’s peak posting windows as it publishes, and suggests slots from real results.
