How to market a mobile app on TikTok, Reels and Shorts

Short video is where a lot of people now discover apps, and it rewards the things small app teams already have: a product that does something specific, and people who know exactly why it matters. What it does not reward is polish for its own sake.

This guide covers what to post, how to make it without a production budget, and the part most teams skip: making sure a tap on a post ends up somewhere useful.

Start with one job your app does

The most common mistake in app marketing is trying to explain the whole app in one post. Nobody scrolling cares about your feature list. They care about one moment in their day that your app makes better.

Write down three to five of those moments. For a car app, it might be warming the car up from the kitchen on a frosty morning. For a budgeting app, the moment you realise you can afford the weekend away. Each moment is a series of posts, not a single one.

Four formats that work for apps

The product demo

Show the app doing its job, start to finish, in under thirty seconds. Use real screen recordings, not mock-ups: viewers can tell, and the real thing builds more trust. Lead with the result, then show how quickly you got there.

The customer story

One person, talking to camera or over footage, in four beats: the hook, the problem, the moment they found the app, and what changed. This is the format often called UGC (user-generated content), and it works because it sounds like a recommendation rather than an advert.

Do not invent customers or present a scripted story as a real review. A clearly framed story ("If you are the kind of person who...") works without pretending.

The faceless explainer

A narrated short over b-roll or screen footage, for the days nobody wants to be on camera. Good for "three things you did not know you could do" and quick how-tos.

The tip

Useful advice in your app's area that stands on its own, even for people who never install. Tips earn follows, and follows are the audience your next demo reaches.

Make the tap go somewhere useful

Here is where most app marketing quietly fails. Someone watches your video, taps the link, and lands on a generic website or the store's search page. Or they already have the app installed, and the link sends them to the store anyway.

A good link does three different things depending on who taps it:

• App installed: open the app, on the screen the post was about.
• App not installed: go straight to the right store listing for their phone.
• On a computer: go to your website.

There is a fourth case worth knowing about: in-app browsers. When someone taps a link inside TikTok or Instagram, it often opens in the platform's own browser, which may not hand the link to your app. A small bridge page that offers a clear "Open in app" or "Get the app" button rescues those taps.

On iOS this relies on universal links, and on Android on App Links. Both require your app and your link domain to recognise each other, so set it up once and test it on a real phone.

Measure installs, not views

Views tell you a post was shown. They do not tell you it worked. To know which posts bring installs you need three things:

1. A tracked link per post, ideally per hook, so every tap is counted.
2. A way to tie the install back to the tap. On Android, the Play Install Referrer carries the click through the install. On iOS there is no equivalent channel, so attribution is less precise; be cautious about any tool that claims otherwise.
3. A report from the app when it is opened from a link, so you can see opens as well as installs.

Put those numbers next to what you posted and when, and patterns appear fast: the formats, moments and hooks that bring people who actually install.

Post every day, but make it sustainable

Consistency matters more than any single post, and that is the hard part for a small team. A few things help:

• Batch the thinking, not just the filming. Decide the week's moments on Monday.
• Reuse screen recordings. A good recording of one flow can carry a dozen posts with different hooks and voiceovers.
• Let drafts come to you. Approving a post takes a minute; starting from a blank page takes an hour.

How Fizzpost helps app teams

Fizzpost writes posts for your app every morning, builds short videos from your real screen recordings with a natural voiceover and captions, and gives each post three hooks with their own tracked links. Links open the app where it is installed and the right store where it is not, with a bridge page for in-app browsers. Connect App Store Connect and RevenueCat, and downloads, proceeds and subscribers sit alongside the posts that came before them.
