Short-form video for solo app developers

A practical system for marketing a mobile app with TikTok, Reels and Shorts when you are the only person on the team.

You shipped the app. The code works, the store listing is live, and now the part nobody taught you begins: getting people to notice it. For a solo developer, short-form video is one of the few channels where a single person with a phone and a laptop can reach people who have never heard of them. It is also a channel that can quietly eat every evening you have.

This guide is about doing it sustainably: a small system you can run next to your day job or your next release, without pretending to be a full-time creator.

Start from the problem, not the feature list

The most common mistake developers make on TikTok, Reels and Shorts is filming a feature tour. A feature tour answers a question nobody in the feed has asked yet. People scroll short-form video for entertainment and recognition, not for a changelog.

Flip it around. Write down the three to five situations in which someone would actually want your app. Not "it syncs across devices" but "you wrote the shopping list on your laptop and you are standing in the shop with only your phone". Each of those situations is an angle: a specific problem, who has it, and why it hurts.

A good angle has three parts:

  • The moment — a concrete scene the viewer recognises in the first second.
  • The friction — what makes that moment annoying, slow, embarrassing or expensive.
  • The resolution — how the situation ends better, which is where your app can appear, or not.

Once you have angles, you have an endless supply of videos, because every angle can be told with a different hook, a different format and a different closing.

Hooks are a writing problem

The first line of a short video decides whether anyone sees the second. Developers tend to be good at this once they treat it as writing rather than as "marketing". Some hook shapes that work without any production budget:

  1. The confession — "I built this because I kept forgetting my own passwords."
  2. The specific frustration — "Nobody tells you your habit tracker is the reason you quit."
  3. The contrarian claim — "You do not need another to-do app. You need fewer lists."
  4. The list promise — "Three things I stopped doing after I started tracking my sleep."

Write ten hooks per angle before you film or render anything. Most will be weak. That is the point: picking the best three out of ten is much faster than trying to write one perfect hook.

Pick formats you can repeat

A solo developer cannot sustain a format that needs a studio, a second person or an hour of editing per clip. Choose formats you can produce in minutes, and that still look intentional.

  • Slideshows — a hook slide, two or three slides that walk through the problem, and a closing slide. On TikTok and Instagram these can go out as native photo carousels. We wrote a whole piece on why they are underrated: Slideshows: the most underrated format.
  • Text over a clip — one strong line of text over a calm, looping background clip. The text carries the message; the clip carries the attention.
  • Green-screen memes — a recognisable reaction clip over a background that shows your problem, with a caption. Easy to overdo; see how to keep them original.
  • Hook plus demo — a short hook followed by a screen recording of the app doing the one thing that resolves the angle. This is where your product finally appears, and it earns its place because the hook set it up.

You can browse how each of these looks on the formats page. The honest advice: pick two formats and get good at them before you add a third.

Not every video should sell

If every post ends with "download now", people learn to scroll past you. A healthier pattern is to let most videos simply be useful or relatable, and to mention the app in a smaller share of them. The ones that do mention it should feel earned: the angle set up a problem, and the app is the natural next step.

This also takes pressure off you. A video that just names a frustration clearly, and makes someone nod, is a perfectly good post. It builds recognition that the next, more direct video can use.

Consistency beats bursts

Posting twenty videos in a week and then nothing for a month teaches the platforms and your audience very little. A steady, modest rhythm teaches both a lot more, and it is far easier to keep up.

Plan in batches. One session a week to write hooks, one to produce the week's videos, and then let a scheduler release them. When you batch, you also notice patterns: which angle keeps producing hooks you like, which format you dread making. Drop what you dread.

There is also an upper bound worth respecting. More posts per account per day is not automatically better, and platforms watch for behaviour that looks automated or spammy. We explain the reasoning, and the cap we use, in What 3 posts per account per day means.

Keep the platform rules in one place

Each platform has its own length limits, aspect ratios and carousel rules, and they change. Keep a single note of what each one accepts and check your formats against it, rather than rediscovering the rules when an upload fails. Our summary lives at TikTok, Reels and Shorts format rules.

A few habits that save time regardless of the current numbers:

  • Produce vertical by default, and keep text away from the edges where the platform draws its own buttons.
  • Keep videos short enough to fit your strictest platform, so one render can go everywhere.
  • Write a separate caption per platform. The same caption rarely reads well on TikTok and LinkedIn.

Measure the right things

Early on, raw view counts are noisy and mostly tell you about luck and timing. More useful questions for a solo developer:

  • Which angle gets people to comment with their own version of the problem?
  • Which hook shape keeps people past the first two seconds?
  • Does anyone mention the app by name, or ask what it is?
  • Do store page visits move in the days after a video that mentioned the app?

Treat each week as an experiment on one variable. Change the hook shape, or the format, or the angle, but not all three at once, otherwise you learn nothing from the result.

Where automation helps, and where it does not

Automation is good at the repetitive parts: turning an angle and a hook into a slideshow, rendering the same idea in several formats, spreading posts across the week, and respecting per-account limits so you do not have to count. It is not good at knowing your users. The angles, the voice and the judgement about what feels honest still have to come from you.

That is the split we designed Reachira around: you bring the angles and the product, and it generates, schedules and publishes videos across your connected accounts, with the free formats such as slideshows and green-screen memes costing no AI credits. If you want to see the flow end to end, how it works walks through it.

A one-week starting plan

If you want something concrete to try this week:

  1. Write down three angles for your app, each with a moment, a friction and a resolution.
  2. Write ten hooks for each angle and keep the best three.
  3. Turn those nine hooks into slideshows and text-over-clip videos.
  4. Schedule them across the week at a calm pace, one account per platform to start.
  5. At the end of the week, note which angle drew the most genuine comments, and write ten new hooks for that one.

That is the whole loop. It is not glamorous, but it is repeatable, and repeatable is what a solo developer can actually sustain.
