◆ FOR MOBILE APPS & APP STUDIOS
Social media automation for mobile apps.
Because nobody finds an app in the store any more.
PostOtter reads your app's website or landing page, works out what the app actually does, then writes and publishes a post a day to Instagram, TikTok, and X — with real vertical video, which is the format your installs come from.
App discovery moved. People find apps in a feed, watch someone use one for eight seconds, and then go looking for it by name — the store listing closes the deal rather than starting it. That makes short-form video the top of your funnel, and short-form video is the single hardest thing for a small app team to produce every day. PostOtter automates that: it builds a profile of your app from your own site, then writes the captions and renders the vertical video daily, on a schedule, to all three platforms.
What an app team actually needs
Vertical video, daily, without an editor
Instagram and TikTok each get a real 9:16 video every day. Not a screenshot with a zoom on it — the format those feeds actually distribute, produced without anyone opening an editor.
Film your own app screens, free
@postotter/video is an MIT-licensed package with no account and no API key. Run it in your repo and it renders vertical video from your app's own components, stylesheet, and fonts — and it knows where a caption can sit without Instagram's own UI covering it.
Your landing page is the only brief
Point PostOtter at your app's site and it reads what the app does, who it is for, the tone you write in, your colours and icon. Nobody writes a content brief, and nobody fills in a calendar.
$14.99 a month, everything in
One price for your app across Instagram, TikTok, and X. No per-channel maths, no tier to upgrade into when you want video, no annual lock-in.
Three platforms, three different posts
The same day's idea is rewritten per platform — hook-first on TikTok, story-led on Instagram, short on X, with hashtag counts that match how each one surfaces things. Cross-posting one caption three times is what makes an app account look dead.
A free first week that really publishes
The trial posts for real to your connected accounts, no card required. You are judging a week of your app's actual feed, not a mockup of one.
PostOtter vs a scheduler
Buffer is the tool most small app teams already have open. The difference is not the calendar — it is who makes the thing that goes in it.
| PostOtter | Buffer | |
|---|---|---|
| Cost for Instagram + TikTok + X | $14.99 / month, all three | $15 / month — Essentials is $5 per channel |
| Writes the caption | Yes, per platform | No — you write it |
| Makes the image | Yes | No |
| Makes vertical video | Yes, daily on IG + TikTok | No |
| Renders from your app's own screens | Yes — @postotter/video, MIT, free | No |
| Schedules and publishes | Yes | Yes |
| Analytics | Basic | Yes, more detailed |
Buffer pricing as published on buffer.com in 2026: Essentials $5 per channel per month, so Instagram, TikTok and X together are $15. See our Buffer pricing guide for the full breakdown. Buffer is a good scheduler and better than PostOtter at analytics — the comparison here is about who produces the content.
The store listing is the end of the journey, not the start
App Store Optimisation still matters for the moment someone searches your name or your category, but it is a conversion lever, not a discovery one. Almost nobody browses a store hoping to find something. They see an app being used, in a feed, and go and get it.
That means the work that grows installs is producing something watchable, repeatedly, for months — which is exactly the work that gets dropped when a two-person team is shipping features. PostOtter takes that specific job: a post a day, every day, with the video made for you.
Your app's screens are the content
The best thing a mobile app has to show is itself in motion: a flow that is faster than people expect, a moment of polish, the one screen that explains the whole idea. Producing that daily means screen recordings, timing, cutting, and captions positioned so the platform's own interface does not sit on top of them.
The free @postotter/video package handles that inside your repo. It compiles your project's real stylesheet and renders 9:16 video from your own components and fonts, so the clip looks like your app rather than a stock template with your colours applied — and it plans which screen gets filmed on which day, so the week is not seven takes of the same home screen. MIT licensed, no account, no telemetry, whether or not you ever subscribe.
Scheduling is not the part that was hard
A scheduler assumes the post already exists. For an app team, it never does — there is no photographer, no editor, and no one whose job is to decide what Tuesday is about. The calendar sits empty and the tool sits waiting.
PostOtter produces first and publishes second. Each day it picks an angle from your app's own content pillars, writes it three ways, renders the visual, and posts at natural-looking times. Everything lands as an editable draft, so you can rewrite a caption or swap a clip before it goes — or leave the week alone.
What it will not do
It will not invent five-star reviews, download counts, or press quotes. If a number is not on your own site, it does not appear in a post — which matters more for apps than most categories, because store listings and ad platforms both take a dim view of claims you cannot back.
It also does not do paid user acquisition, ASO keyword research, or replying to reviews. It does the daily organic production and publishing, which is the part that otherwise quietly stops happening.
◆ MADE BY POSTOTTER, FOR POSTOTTER
Real posts on our own accounts. Your free week looks like this.
Same brand, three different posts. Instagram and TikTok share the render; the captions don't. Each one is written native to the platform it's on, and the hashtags are weighted the way that platform's discovery actually works. That is why Instagram gets ten and X gets two.
Here is the plain version of what PostOtter does. 1) You drop in your website URL. PostOtter reads it to learn your brand voice, what you sell, and how you talk. 2) You connect your accounts. Instagram, TikTok, and X. That is it.
#socialmediamanager#marketingautomation#smallbusinessowner#solopreneur#founderlife#brandvoice#instagramreels#tiktokmarketing#PostOtter#PostOtterAISee it on InstagramYou're juggling a line out the door, and your “scheduler” is still waiting for you to write the post. That is not help. PostOtter learns your brand voice from your website, then creates, schedules, and publishes a post every day to X, Instagram, and TikTok.
#socialmediamarketing#smallbusinessowner#solopreneur#contentmarketing#instagramreels#tiktokmarketing#marketingautomation#PostOtterSee it on TikTok
You open a scheduler and it just stares back, waiting for a caption you don't have. So you post nothing. Again. PostOtter isn't a scheduler—it creates, schedules, and publishes daily to X/IG/TikTok (images + real Reels/TikTok video). Try it today.
#smallbusinessowner#PostOtterSee it on Xwe didn't lift a finger: no captions written, no hashtags picked, no content made, no times set, nothing published by hand
but every one of them was ours to change first: rewrite the caption, swap the hashtags, upload your own photo or video, move it to another day. and so is every post you get.

◆ QUESTIONS
App marketing FAQ
Does this do App Store Optimisation?
No. PostOtter does organic social — writing, making, and publishing a post a day to Instagram, TikTok and X. ASO is a different job, done on your store listing. The two work together: social is where people discover the app, the listing is where they decide.
Can it show my actual app, not stock footage?
Yes, through @postotter/video — a free MIT package you run in your own repo. It compiles your project's real stylesheet and renders vertical video from your own components and fonts, and plans which screen is filmed on which day. No account, no API key, no telemetry.
What if my app has no website, only a store listing?
PostOtter builds the brand profile by reading a web page, so it needs a site or landing page to read. A single-page site for the app is enough — it does not need to be elaborate, it just needs to say what the app does and who it is for.
How much gets posted?
A post a day on each platform — roughly 90 a month, of which 14 a week are video for Instagram and TikTok and 7 a week are images for X.
Will it claim things about my app that are not true?
No. Posts are written against the claims your own site makes. It will not invent download numbers, ratings, testimonials, or press mentions — if it is not on your site, it does not go in a post.
What does it cost, and is there a trial?
$14.99 a month for one app across all three platforms, billed monthly. The first week is free, needs no credit card, and publishes for real so you can judge actual posts. Cancel any time.
I have several apps. Can I run them all?
Yes. Each app is added as its own brand with its own voice, connected accounts and schedule, billed at $14.99 each. You switch between them from one login.
