How to Market an App on TikTok and Instagram with UGC

Why short-form video is the cheapest way to market an app

Paid installs cost money from the first click. Organic short-form costs time. And on TikTok, a new account isn't locked out: TikTok has said that follower count isn't a direct factor in what its For You feed recommends. How people react to the post matters more.

The audience is large. Pew Research Center found that 37% of US adults use TikTok, including 63% of adults under 30, and that about half use Instagram.

Be clear about the limits before you commit a month to it:

• It's slow and uneven. Expect weeks of small numbers. One post can do more than the previous twenty combined.
• Views aren't installs. A funny post with huge reach can send fewer people to the App Store than a plain demo with a fraction of the views.
• Some products show better than others. Problems you can show in three seconds (money, food, fitness, study, languages, focus) suit it. A B2B tool with a six-month sales cycle will get less from it.
• It can't fix retention. If people install and leave, more installs only make the leak bigger.

Find your angle: the problem, the aha moment, the result

Before you make a post, write down three things in your users' words, not your marketing words.

1. The problem. What they're tired of. Not "inefficient meal planning" but "My partner and I argue about what to eat every single night." That line is from the homepage of Supperly, a sample meal-planning app we set up, and Feedrick turned it into a talking video.
2. The aha moment. The first time the app does its job. For Supperly, it's a week of dinners planned in five minutes, starting from what's already in the fridge.
3. The result. What's different a week later. The bag of spinach gets eaten instead of thrown away.

Then write ten versions of the problem. Find the exact words in reviews of competing apps (the two- and three-star ones are the most specific), Reddit threads in your niche, your support inbox and your onboarding survey. Each version is a hook, and each hook can become several posts.

One problem can split into many angles. For BudgetBird, a sample budgeting app for freelancers, "a big invoice isn't a big month" became a silent story. "POV: Sunday night, you're about to look at your bank balance" became a meme. "Rich for ten days vs. steady all quarter" became a carousel. Same problem, three ways in.

5 TikTok and Reels formats that drive installs

Each format below has one job. Mix them rather than picking one and stopping.

1. The problem POV

Someone acts out the moment the problem hits, with text on screen and no talking. Viewers recognize themselves before they realize it's about an app. A post for DeepNook, a sample focus app, opens on "POV: YouTube is one click away and nobody is watching you" and only names the app near the end. Feedrick calls this format a silent story.

2. "I found this app": reaction plus demo

A person reacts to something on their phone, then the video cuts to a screen recording of the app doing its job. It's the closest organic format to an ad, and the one most likely to get comments asking for the app's name. The demo matters more than the reaction. Record your aha moment in 9:16, keep it under 15 seconds, and skip the setup screens.

3. The slideshow

Five or so slides, one idea per slide, with the app appearing around slide three or four. Slideshows are cheap to make, which makes them a good place to test hooks. Our guide to TikTok slideshows covers the templates that work.

4. The meme

One picture, one punchline about the problem. Memes rarely explain the product, but people send them to friends, and that builds familiarity for the posts that do explain it. TinyLoop, a sample habit app, used "POV: you're sick in bed and the 20-page goal stares at you." See our meme marketing guide for more.

5. The one-line opinion

A person says one strong line to camera, with captions. Myths and mistakes suit it: "Walking breaks aren't cheating. They're the plan," from StrideBack, a sample running app for people getting back into it. One line, one claim the viewer can agree or argue with.

How many posts you need, and how to make that many

Nobody can give you a number of posts that guarantees results. What you can plan around is that every post is one test, most tests fail, and you learn something from each one.

A workable start for a solo founder is one or two posts a day on TikTok, with the same posts going to Instagram and YouTube. That's 30 to 60 posts a month. Give each angle five or six posts in different formats before you judge it, because one flop tells you very little.

That's a lot to make by hand. Here is what a month looks like in Feedrick credits, where a photo post (meme or carousel) costs 1 credit and a video costs 2:

• 30 photo posts and 30 videos: 90 credits, which fits Starter ($29 a month, 100 credits).
• 60 photo posts: 60 credits, also Starter.
• 60 videos, or 120 posts split evenly: 120 or 180 credits, which fits Growth ($69 a month, 280 credits).

The Free plan (12 credits to start, then 5 a month, TikTok only, with a watermark) shows you what the posts look like for your app. It won't cover a daily schedule. See pricing for the details.

Making UGC for your app without hiring creators

UGC-style posts look like a person filmed them on a phone, not like a brand made them. There are three ways to get them.

• Film them yourself. Free, and as a founder you're the most believable person to talk about the app. It's also the slowest option, and few founders keep it up daily.
• Hire creators. Real people on camera help with trust. But each video costs money and takes days, so testing 30 hooks this way gets expensive. Our UGC marketing guide covers where to find creators.
• Use AI UGC. AI-made people act out the scene, react or say the line. It's fast and cheap enough to test many hooks. It's weakest where trust depends on a real person's experience, such as health claims.

Feedrick is an AI social media agent built for the third option. You paste your website, App Store or Play Store link. It reads your pages in about a minute (what you sell, who it's for, what they're tired of and what you can prove), then makes posts in five formats starring about 30 AI influencers. They're AI-made, so no real person's face is used. Our AI UGC guide goes deeper.

Rules for using AI influencers

• Label it. TikTok's Community Guidelines require creators to label AI-generated or significantly edited content that shows realistic scenes or people. Meta may require its "AI info" label on photorealistic video or realistic-sounding audio on Instagram and Facebook. Both rules are as of October 2026. Every TikTok post Feedrick publishes is marked as AI-generated and as promoting your own brand, and its YouTube posts are marked as containing synthetic media. On other platforms, check the post settings.
• Don't pass an AI person off as a real customer. Acting out a scene is fine. Captioning it as a real user's review is not. The FTC's rule on fake reviews and testimonials, announced in August 2024, bans fake consumer testimonials, including ones made with generative AI.
• Keep claims true. If a post says "five minutes to plan a week," the app has to do that.

Posting to TikTok, Reels, Shorts, X, LinkedIn and Threads

Make each post once, in 9:16, and send it everywhere it fits. A few platform differences matter.

• TikTok. If you post as a business, use TikTok's Commercial Music Library. TikTok says businesses can't use the general music library for commercial content (as of October 2026).
• Instagram Reels. The same videos work here, and Instagram reaches a wider age range than TikTok. Carousels work too, and Instagram allows up to 20 photos or videos in one.
• YouTube Shorts. Worth the extra upload. Links in Shorts descriptions and comments stopped being clickable in August 2023, so point people to your channel or to an app store search instead.
• X, LinkedIn and Threads. These matter more for SaaS. Memes and one-line opinions suit X and Threads. Carousels that teach one thing suit LinkedIn.
• Upload clean files. Don't cross-post a video you downloaded from another app with its watermark on it. TikTok's For You feed standards treat content with someone else's visible watermark as unoriginal, which makes it ineligible for recommendation.

Feedrick handles this step for the posts you keep. It schedules each one at a good time and publishes it to the accounts you've connected. Starter and Growth cover TikTok, Instagram, YouTube, Facebook, LinkedIn, X and Threads. See how it works.

Measuring installs and signups from organic social

Views tell you a hook works. Installs tell you a post works. Track both, and don't confuse them.

• App Store campaign links. App Store Connect lets you create campaign links with a provider token (pt) and a campaign token (ct). Make one per platform, such as ct=tiktok and ct=reels, and put it behind your bio link. Apple shows a campaign after about 24 hours, once at least five people have downloaded the app for the first time through it.
• Google Play UTM links. Play Console's acquisition reports count visitors who reached your store listing from a UTM-tagged link under "Tracked channels (UTM)."
• UTMs on your website. For SaaS, tag the bio link with utm_source and utm_campaign and watch signups in your analytics.
• Ask in onboarding. Add one question: "Where did you hear about us?" Many installs from short-form never touch your link. People see a post, then search for the app by name days later.
• Watch the baseline. Compare installs from app store search on the days after a post takes off with your normal days. That lift is often the clearest sign a post worked.

Judge a format on installs per post over a few weeks, not on its best single post.

How to market an app in 30 days: a launch plan

Week 1: angle and setup

• Write down your problem, aha moment and result, plus ten versions of the problem.
• Record a 9:16 demo of the aha moment, under 15 seconds.
• Set up TikTok, Instagram and YouTube accounts with a one-line bio and a tracked link.
• Paste your link into Feedrick and review the first batch. Keep or skip each post. Every choice teaches the next batch what to make.

Week 2: volume

• Post once or twice a day, using all five formats.
• Try every hook in at least two formats.
• Reply to every comment, especially the ones asking what the app is.

Week 3: double down

• Find the three posts with the most shares or app-name comments. Make five variations of each: a new opening line, a new person or a new format.
• Drop angles that got nothing after five or six posts.

Week 4: measure and decide

• Check installs by campaign link, and read your onboarding answers.
• Decide which angles, formats and platforms to keep.
• Set a cadence you can hold for three months. A steady quarter tells you more than a busy first month.

If nothing has moved after a month, try new angles before you give up on the channel. The hook is the cheapest part of a post to change.
