The App Ad Creative Guide We Hand to Every New Client

01Why app ad creative now does the targeting for you

Most new clients arrive believing their problem is audiences or bidding. When we open the account, the problem is almost always the app ad creative. There are six ads live, four of them variations of the same screen recording, and the best one has been running for three months. The campaigns are not broken. They are starving.

Here is why. Since Apple’s App Tracking Transparency arrived with iOS 14.5 in April 2021, apps have had to ask permission before tracking people across other companies’ apps and sites. Detailed targeting lost much of its precision, and the platforms responded with broad, automated delivery. In that setup, the creative is the targeting. The words in the first frame, the face on screen and the problem you name all decide who stops, and the platform learns who to find next from those people.

So when we say creative is the biggest lever in app growth, we do not mean it in a vague, brand-building way. We mean it mechanically. A fitness app ad that opens on a tired parent at 6am finds a different audience from one that opens on a gym regular lifting heavy. Same app, same budget, completely different cohort.

What this guide covers, and what it leaves out

This is the creative half of the system. If you want the full picture of channels, budgets and scaling rules, our guide to app user acquisition covers that. Here we stay focused on concepts, hooks, formats, testing, fatigue and briefs: the work that decides whether your media budget has anything good to spend on.

02The app ad creative concepts that keep working

A concept is the core idea of an ad: the reason someone should care. Formats, edits and hooks all sit on top of it. Across the subscription apps, games, fintech, health and ecommerce apps we run, a handful of concept families keep producing users who stay.

The mistake is choosing one family and living in it. A language learning app we picked up had spent a year on polished feature demos. They were clean, on brand and flat. When we added a creator talking about freezing up on a work call in another language, the cost per Day-7 learner dropped noticeably in the first fortnight. The product had not changed. The reason to care had.

Concepts that tend to bring the wrong users

• Pure curiosity bait. Odd visuals that earn clicks but say nothing about the app. Great click-through rate, poor Day-1 retention.
• Fake gameplay. Showing a puzzle mechanic the game barely uses. You will pay for installs that uninstall within the hour.
• Discount only. Fine as a test, dangerous as a strategy. It teaches the platform to find people who wait for deals.

03Hooks: winning the first three seconds

On feed platforms, most of an ad’s result is decided before anyone hears the app’s name. We treat the opening three seconds as a separate creative problem, and for every concept we write at least three hooks before anything is filmed.

A good hook does one of three jobs: it names the viewer, it names their problem, or it shows something they did not expect. The best do two at once. “If you have tried three budgeting apps and quit all of them” names the viewer and the problem in a single line.

How we write hooks in practice

1. Start from the one sentence that describes who the ad should stop.
2. Write five openings: one call out, one pain point, one pattern break, one result first, one question.
3. Cut anything that needs sound to make sense. Many people watch muted, so the on-screen text has to carry the hook alone.
4. Keep the three strongest and film or edit them onto the same body, so the test isolates the hook.

The body of the ad sells the app. The hook decides whether anyone is still there to hear it.

04App ad creative formats for each channel

The same concept needs to be cut differently for each platform. People use TikTok, Instagram Reels, YouTube and Snapchat in different moods, and an ad that ignores that mood looks like an ad. We brief one concept and plan several native cuts from the start, rather than resizing one master file at the end.

For TikTok, boosting real creator posts usually beats anything that looks produced, and our TikTok Spark Ads work is built around that. On Meta, our Meta app campaigns team runs video and static concepts side by side, because statics are cheap to make and often tell you which message wins before the video is even edited. For apps that need explaining, YouTube Demand Gen campaigns give you space for a proper walkthrough, and for younger audiences Snapchat ads reward speed and a lighter tone.

Do not forget the store page

Your ad is only half of the creative. The other half is the page people land on. If the ad promises a calm sleep routine and the first screenshot shows a dashboard of graphs, you lose people at the door. Apple’s custom product pages let you create additional versions of the product page for different ads, and Google Play offers custom store listings. Our app store optimisation team builds those pages from the same brief as the ads.

05An app ad creative testing framework that respects your budget

Creative testing goes wrong in two ways. Either nothing is tested properly, so the account runs on gut feel, or everything is tested at once, so no test gets enough spend to mean anything. The fix is structure: decide what you are testing, at what level, and what result counts as a win before you launch.

Level 1: Concept tests

Three to five genuinely different concepts, each with its best guess at a hook. The question is simple: which reason to care finds users who stay? We read these on cost per activated user first, then cost per Day-7 user once enough data has arrived.

Level 2: Hook tests

Take the winning concept and run three to five hooks on the same body. This is where most of the extra performance hides, and it is cheap because you are only re-editing the opening.

Level 3: Execution tests

Now try different creators, lengths, music, captions and calls to action. These tests matter, but they rarely rescue a weak concept, which is why they come last.

On iOS your read is also limited by privacy-safe attribution, so we look at creative results alongside product analytics and blended trends rather than trusting any single dashboard. The broader app marketing setup has to support this, otherwise creative decisions end up based on whichever number looks best that day.

06Spotting creative fatigue before it costs you

Every winning ad wears out. The only question is whether you notice before or after it has dragged your numbers down. On higher spend accounts we often see a strong concept lose its edge within a few weeks, while on smaller accounts the same ad can last for months.

• Frequency rising while click-through falls. The same people are seeing the ad and caring less each time.
• Cost per activated user creeping up week on week with no change in targeting, budget or product.
• Hold rate dropping in the first seconds. The hook has stopped surprising anyone.
• Comments turning stale or negative, such as “I keep seeing this” on social placements.
• The platform shifting spend away from an old winner on its own, which is often an early warning.

None of these alone proves fatigue. Two or three together usually do. When we see that pattern we do not pause the ad straight away. We start feeding its replacement into the same campaign first, so the account never runs dry.

07Iterating winners without killing what made them work

When something works, the temptation is to duplicate it twenty times with tiny changes. That rarely helps. The platform tends to treat near copies as the same ad, and you learn nothing new. Good iteration keeps the core of the winner and changes one meaningful thing at a time.

A meal planning app we work with had one UGC ad that carried the account for weeks: a parent opening an almost empty fridge on a Wednesday. We kept the fridge and the Wednesday, and changed the person, the room and the first line. Six iterations later, four were still pulling their weight. The original idea lasted far longer because it kept looking new.

When to stop iterating

If three solid iterations of a concept all underperform the original, the concept itself is tiring, not just the execution. That is the signal to move the budget towards your next concept test rather than squeezing another edit out of an idea the audience has already seen.

08Briefing creators and designers for app ads

Weak briefs produce weak ads, and most app briefs are weak in the same way: they describe the app instead of the viewer. A creator does not need your feature list. They need to know who they are talking to, what that person is struggling with, and what one thing the app does about it.

What goes in every brief we send

1. The viewer in one sentence. Who the ad should stop, in plain words.
2. The problem. The specific moment of frustration, not a category.
3. The single message. One benefit, shown on screen, not just said.
4. Three hooks to film. Written out, with on-screen text for muted viewing.
5. What to show in the app. The exact screens, in order, with test accounts ready.
6. Do and do not. Claims to avoid, brand words to use, anything legal needs to approve.
7. Deliverables. Vertical first, plus any square or horizontal cuts, and raw footage for re-edits.

We ask for raw footage every time. Many of our best hook tests come from re-editing footage we already own rather than paying for new shoots. Our video content production team films both creator style and polished pieces, and for statics and end cards our Canva design services keep turnaround fast. When the product screens themselves need tidying for ads or the store page, our Figma design work handles the mock-ups.

09Putting your app ad creative system into practice

The apps that win on creative are rarely the ones with the biggest production budgets. They are the ones with a rhythm: a weekly slot for new hooks, a monthly batch of new concepts, a clear rule for what counts as a winner, and a habit of reading results on retained users rather than clicks.
