Most app launches get one post. "We're live, link in bio." A few friends like it, and by Tuesday the launch is over. You spent months building the thing. You also already have what you need for more than one post: a problem worth solving, a screen recording and a few early users.
Start with one short clip
Most of what follows gets easier with 20 to 30 seconds of your app doing its main job. Not a tour of every screen. One person, one task, start to result.
Record it on a real phone with real-looking data and notifications off. Move slowly, and stop on the screen that matters.
A raw screen recording looks unfinished in a feed, so put it in a phone frame. If you're building for mobile, MobileStudio does this on the phone itself: it turns a screen recording into a demo with device frames, zooms and backgrounds, and exports it in 9:16, 4:5 or 1:1 with no laptop step. It's on Google Play now, with iPhone coming.
The five posts
1 · The problem, before the product
Make this a carousel. Put the annoying thing on the cover, in the words your users would use. Spend the slides on why it's annoying, and don't name your app until the last one. People share a problem they recognise far more readily than an announcement.
2 · The demo
This is your clip, with one line on top saying what's happening. Post it to Reels, TikTok and Shorts. Then pin it, because it's the post that answers "what does this actually do?"
3 · How it works, in three steps
Three slides, three verbs. If it takes five, your explanation needs work, and that's useful to find out now.
4 · One real number
Sign-ups in the first week, minutes saved on a task, how many people asked for it. Small is fine, because a small true number is more interesting than a big vague claim. If you don't have a real one yet, skip this post.
5 · Your first user
Ask one early user what they tried before, and what changed. Use their words, and get their permission first. A sentence from someone who isn't you does more than anything you can write about yourself.
Make it look like one launch
Five posts that look like they came from five companies don't add up to anything. Use the same colours, the same fonts and the same logo every time.
That's the job PostPop does. Paste your website and it reads your colours, logo and fonts. Type one line and it writes and designs the post on your brand. Any carousel also exports as a 1080×1920 MP4, with each slide held for as long as its words take to read, so the problem post and the three steps can go to Reels too.
A simple week
Monday, the problem. Tuesday, the demo. Wednesday, how it works. Thursday, the number. Friday, your first user.
That's five posts from one recording and an afternoon of work. And on Saturday, you still have a launch people remember seeing.
