The calendar companion for Buffer
Buffer publishes. PostIQ plans.
Your posts are scheduled. Is your content actually planned? PostIQ shows what’s coming, spots the open slots, and holds the ideas and to-dos that aren’t ready to publish yet.

Buffer sign-in loads your scheduled posts and enables Buffer actions. Free during public beta. One of the earliest companion apps built on Buffer’s public API. Independent; not endorsed by Buffer.
How it works
Buffer keeps posting. You keep the plan.
Most content gaps aren’t a publishing problem. They’re a planning one: ideas sit in notes, to-dos sit somewhere else, and the thin days go unnoticed. PostIQ puts them on one calendar beside your queue.
See the gaps
Open slots appear on the posting days you choose, so you can spot the thin parts of the week at a glance.
Fill or plan
Fill a slot from the Shelf in one tap, or add a note, to-do, or idea. Send to Buffer when you’re ready.
See it for yourself
Go ahead. Plan something.
Drag a plan to another day, fill an open slot from the Shelf in one tap, or add something in plain English, then Undo. This sample never touches Buffer.

One-tap planning
See the whole plan. Not just the scheduled posts.
The Today card brings today’s posts and to-dos into view. A dashed open slot can suggest a starred evergreen post, so you can fill a gap without starting from zero.
- Solid cards are confirmed Buffer posts; outlined cards are your plans
- Quick add understands “Fri: film B-roll” and “todo tomorrow: review captions”
- Drag to reschedule, with Undo if you change your mind
Room for ideas
Keep the ideas that aren’t ready yet.
Keep past posts and ideas on the Shelf. Give an idea a target date to see it beside the rest of your calendar; it stays clearly marked as not scheduled. Holidays, backups, and calendar exports are close at hand in the menu.
- Star evergreen posts for one-tap fill suggestions
- Download or restore a backup of your local planning work
- Export notes and plans to your calendar app

Your Buffer connection
You decide every Buffer action.
PostIQ uses Buffer’s public API with OAuth (PKCE). When you sign in, it can:
- Read your channels, scheduled queue and recent posts
- Create a draft, queue a post or schedule one only when you choose that action
- Leave existing Buffer posts alone when you change plans, rhythms or days off
- Disconnect from PostIQ settings, or revoke access in Buffer, at any time
An independent product
PostIQ is built and run by one person on Buffer’s public API. It is independent and not endorsed by Buffer. Buffer remains your publishing home. Buffer also featured PostIQ as an example app in its Buffer Commit contest.

Common questions
Quick answers.
To see your scheduled posts or send anything to Buffer, yes. You can open the calendar preview, add notes, and save content without one.
You choose posting days in the calendar’s Posting schedule. Dashed open slots show days where a confirmed Buffer post is not loaded; notes, drafts, and dated ideas remain plans.
No. Content goes to Buffer only when you choose Draft, Queue or Schedule. Changing a rhythm, marking days off, or planning a target date never moves, cancels or deletes a Buffer post.
The real app, without your Buffer data: the calendar, notes and actions, Shelf, Compose drafts and settings, all stored in your browser. Open slots needs connected channels to measure anything. A short three-step tour opens the first time you visit; skip it whenever you like, or restart it from Take a tour in the app.
Notes, schedules, days off, dated Shelf ideas and settings are kept in your browser’s local storage. A snapshot carries its shared content inside the link itself. See the privacy policy and the beta limits guide.
No. PostIQ is independently built by Ben Campbell using Buffer’s public API, one of the earliest companion apps for it. It is not endorsed by Buffer. It’s free during the public beta, and features may change as Buffer’s API evolves.
