Plan a month of posts in one sitting
A calendar, ready ideas, your Instagram grid before you post, and your own best time to post. Free, private, no sign-up.
Instagram grid preview
Add the photos you plan to post. Tap one, then another, to swap them. Photos never leave your device and are cleared when you close the page.
Starting points
General guidance, not a rule. Your own results (right) beat any chart.
Your best time
Log views for posts you've published (in the calendar: time + views). After 5 posts, Plotfern shows the day and time slot where your posts did best.
Questions
When is the best time to post?
General starting points: Instagram Tuesday to Thursday around 11 am to 1 pm or 7 to 9 pm, TikTok weekday evenings, YouTube weekend afternoons, all in your audience's time zone. Your own results matter more: log a few posts and Plotfern shows your best day and time.
Is Plotfern free?
Yes: plan 4 weeks ahead, the 60-idea bank, a 9-photo grid preview and your own best time, no sign-up. Pro is $9.99 once for unlimited months, a 30-photo grid and CSV/calendar export. Plus ($2.99 a month or $24.99 a year) adds a new dated idea pack on the 1st of every month.
Does Plotfern post for me?
No. Plotfern plans; you post. It never logs in to any social account.
Why not Planoly or Later?
Planoly starts at $14 a month and Later at $18.75 a month billed yearly; both also schedule posts for you. If you post yourself and want a private planner, Plotfern Pro is $9.99 once.
Where is my calendar stored?
In this browser. Export a CSV with Pro to keep a copy or move it to another device.
