單人創辦人如何製作 TikTok App 廣告：實用指南

If you want to know how to make TikTok ads for an app, here is the short answer: pick one problem your app solves, write three different hooks for it, film or generate a vertical video around 10 seconds long that shows the app on a phone, and test the hooks with a small budget before you spend real money on creators. The hook matters more than the edit. The rest of this guide walks through each step.

Why app ads on TikTok are different

People on TikTok are not looking for apps. They are scrolling. Your ad has to look like the content around it, earn the next second, and make the app feel useful before the viewer swipes away. Polished brand videos with a logo intro usually lose to a person holding a phone and talking plainly about a problem.

That is good news if you are a solo founder. You do not need a studio. You need a clear message and a way to test many versions quickly.

Step by step: how to make TikTok ads for an app

1. Pick one problem, not a feature list

Write down the single problem your app solves for one type of person. "Track your expenses" is a feature. "I never know where my money went at the end of the month" is a problem. One ad, one problem. If your app solves three problems, that is three ads, not one ad with three points.

2. Write three hooks for that problem

The hook is the first one to two seconds. It decides whether anyone sees the rest. Write three hooks with different angles so you can learn which one works:

• 1. Problem hook: "If you never know where your money went this month, watch this."- 2. Discovery hook: "I found an app that finally made me stop overspending."- 3. Before and after hook: "This was my budget in January. This is it now." Do not open with your app name or logo. Nobody knows it yet, so it gives them no reason to stay.

3. Keep it short and vertical

Use 9:16 vertical video. Aim for around 10 seconds for a first test. Short ads are cheaper to make, easier to watch to the end, and faster to iterate. A simple structure works:

• Seconds 0 to 2: the hook- Seconds 2 to 7: show the app on a phone solving the problem- Seconds 7 to 10: one clear next step, like "link in bio" or "try it today" ### 4. Show the phone, with a person

The most common format for app ads is a person holding a phone and talking to the camera as if recommending it to a friend. This is the UGC (user generated content) style. It works because it looks native to the feed and shows the product in use.

Make sure the screen is readable. Use your best screen: the moment the app delivers value, not the login page or the settings menu.

5. Add captions

Many people watch with the sound off. Burn in captions for the key lines, especially the hook. Keep the text large and inside the safe area, away from the bottom where TikTok puts its own buttons and caption.

6. Make several versions at once

Do not make one ad and wait. Make three to five versions: same app, different hooks, maybe a different person or setting. You are not trying to make the perfect ad on day one. You are trying to find which angle gets attention.

7. Test with a small budget, then scale the winner

Run the versions side by side with a small daily budget. Watch the early signals: how many people watch past the first seconds, and how many click. Kill the losers fast. When one hook clearly wins, put more budget behind it and make new variations of that winning angle.

8. Pay real creators only for proven angles

Real creators can be great, but they cost time and money, and most first ideas do not work. Test the hook cheaply first. Once you know which message gets clicks, brief a real creator to redo that exact angle. You will waste far less.

Ways to produce the video

You have three realistic options:

• 1. Film it yourself. Free, but slow, and not everyone is comfortable on camera.- 2. Hire UGC creators. Authentic, but you pay per video and wait for delivery, which makes testing many hooks expensive.- 3. Use an AI UGC tool. Fast and cheap for testing many versions. The creators are AI-generated, so use it to find the winning angle quickly. For option 3, I built agent-media (https://agent-media.ai/?utm_source=devto&utm_medium=seo&utm_campaign=how-to-make-tiktok-ads-for-an-app) for exactly this testing stage. You give it an app screenshot and get back a 10-second vertical UGC video ad: an AI creator holding your phone and talking about it. No filming, no actors. You can use it in the web Studio or straight from Claude, ChatGPT or Cursor via MCP. Plans start at $14.90/mo with no watermark. You download the MP4 and post it yourself.

Common mistakes to avoid

• Opening with the logo. Start with the problem.- Explaining every feature. One problem per ad.- Unreadable screens. Zoom in on the moment that matters.- One version only. You cannot learn from a single ad.- Scaling too early. Wait until one hook clearly beats the others. Making TikTok ads for an app is mostly a testing game. The founders who win are not the ones with the best first ad. They are the ones who test the most hooks for the least money and double down on what works.
