How high-performing app teams get new creatives live in half the time (checklist included)

App creatives are the images and videos app marketers use to win installs, on App Store listings and in paid user acquisition campaigns. They include screenshots, app previews, icons and the ad creatives that run on Apple Ads, Google Ads, Meta and TikTok. As of October 2026, they also include the App Store creative assets, a new category you can upload today.

A repeatable process gets new creatives live faster. At the app businesses SplitMetrics works with, which skew toward mid-size and enterprise budgets, a new set usually takes 4 to 8 weeks, and well-prepared teams do it in 2 to 4. Design is rarely the longest step. The time goes to rework and to approvals between teams that each own part of the result.

Follow this guide and your next creative set can go live in weeks, not months. Grab the free checklist to put it into practice.

Why does app creative production take 4 to 8 weeks?

Most of that time goes to coordination. Three teams have to agree before a change goes live, and each owns a different part of the result:

• The brand team owns the visuals, including colors, typography, logo use and the claims the company is willing to make.
• The performance marketing team owns the metrics the creatives are judged by, such as tap-through rate, conversion rate and cost per install.
• The mobile development team owns deployment, because changes to the store listing have often gone out with the next app release.

Each team can stop a change, and none can move it forward alone. A draft that suits performance goes back to brand for revisions, and the approved version then waits for a release slot. For App Store creative assets, that last wait gets shorter: new Asset Library lets you upload and submit assets without an app version update.

Rework takes longer than design

Per our customers, the slowest part of the whole process is rework. The process often starts with a vague brief, and from there everyone has their own opinion about what “good” looks like. Each round of feedback creates a new version, and that version goes back through approval.

SplitMetrics suggests planning around the number of hypotheses the team needs to test, rather than the number of assets. A plan built on hypotheses links every creative to something the team wants to learn.

What should an app creative brief include before production starts?

An app creative brief should include the audience, the message and the metric that will judge the creative. All of it goes on paper before anyone opens a design file. Here’s what a complete brief looks like for a bill-splitting app:

1. The audience. Users researching and comparing bill-splitting apps in the App Store.
2. The problem the audience wants to solve. Splitting a restaurant bill with friends without doing the math at the table.
3. The objection the creative answers. “I don’t have time to learn another app.”
4. The message you want to test, written as one sentence. “Split any bill in three taps.”
5. Where the creative will run. The first screenshot on the store listing, where people give you a few seconds. A search ad or a social video gives them a different amount of time to look, so the same message may need a different treatment.
6. The metric that will judge the creative. Conversion rate from product page view to install. Everyone who approves the creative agrees on this before design starts.

When the last point is missing, every reviewer judges the creative by a different standard. That usually leads to more rounds of rework.

Tap-through rate and install quality can point in opposite directions

A creative can win on tap-through rate and still lose on installs. Take a game ad that shows a level players only reach after weeks of play. It earns the tap, but the install never follows, and the players who do install leave within the first week.

That’s why the brief uses one metric to judge every variant, for example the conversion rate from impression to install or day-7 retention. The brief also says which result stops the test. If installs fall, a high tap-through rate doesn’t make the creative a winner.

A brief can only work when everyone on your team saw and approved it before jumping to the design stage. It should be used as a reference point for all reviewers

Who should own app creatives, and who signs off?

App creatives should have one owner. That person owns the creative roadmap across the brand, performance marketing and mobile development teams. Without an owner, nobody can set the order of approvals or settle a disagreement between teams. In many of the app businesses we work with, store creatives sit between teams, and a product manager often ends up owning them by default, next to their main job.

Every reviewer needs a defined role

Between 3 and 6 functions signing off on a creative is normal in the app businesses we work with. The delay usually comes from reviewers without agreed roles, rather than from the number of reviewers. Here are the questions you need to answer:

• Performance marketing checks whether the creative can reach the metric in the brief.
• Brand checks whether the creative stays inside the brand guidelines.
• Legal or product checks whether every claim is accurate.
• The owner gives the final approval.

With one question each, the reviews can run at the same time, so the creative doesn’t wait in a queue.

Legal approval is several separate checks

Not every creative goes through legal review. It mostly matters for large brands and for apps in categories under legal scrutiny, such as gambling. If your team does have a legal step, note that “Legal” is often written into the approval plan as one item. In practice, it covers different checks with different stakeholders and lead times. The table below shows the ones we see most often:

Mapping these checks separately lets you start the slowest one first.

Brand guidelines and creative testing can work together

A brand team that blocks testing usually does it to keep the brand consistent across every channel. SplitMetrics recommends agreeing on what can be tested inside the brand guidelines before any test starts. In practice, that works in four steps:

1. Agree on a creative toolkit with the brand team. It lists the approved visual principles, typography and claims, and what can change by channel.
2. Start with low-risk variables. Message order, use case emphasis and format work well as first tests.
3. Agree on the test design before launch. Write down what changes, what stays the same and how long the test runs.
4. Run a pilot in one market first. A clear result there makes the case for a wider test.

With an owner and clear roles, a creative gets approved faster. The test that follows still needs the right method to give a result you can trust.

How do you know a creative test result is reliable?

A creative test result is reliable when the test has enough traffic and conversions to detect a difference that matters to the business. The number of days a test ran doesn’t tell you that on its own. We don’t use a fixed test length. On high-volume paid traffic, a test usually needs 1 to 2 weeks. Low-volume markets and apps with low conversion rates need longer.

Calling a test early produces false winners

Calling a test as soon as one variant pulls ahead is a common way to end up with a false winner. The early lead often comes from something other than the creative:

• A small sample, where a few conversions swing the result.
• Day-of-week patterns, when the test hasn’t run for a full week.
• Changes in ad delivery while the test is running.
• A short promotion that lifts one variant for a few days.

Agree on the stopping rule before the test starts. A solid rule has three parts:

1. A minimum run time. At least one full week, so every day of the week is represented. Run two weeks if your traffic is low or the difference between variants is small.
2. A confidence threshold. Don’t call a winner until the test reaches the confidence level you set up front (90 to 95% is typical), and not before the minimum run time is also met.
3. A written definition of a win. One primary metric, taken from the brief. For example: “Variant B beats the control on conversion rate at 95% confidence after at least 7 days.”

You can run these tests with product page optimization in App Store Connect, Google Play’s store listing experiments or CPP Experiments in SplitMetrics Acquire.

A test with no clear winner still answers a question

First, check whether the test could have detected a meaningful difference. If traffic was too low, the test was too small to answer the question. If traffic was high enough and the variants still performed the same, the change was too small to matter to users. The next test should change something bigger, such as the audience, the use case or the main promise of the app.

These testing principles apply to every channel. The App Store creative assets add a new type of creative to brief, approve and test. Once your assets are ready, you can submit them for approval in App Store Connect. From there, product page optimization lets you test alternative header visuals organically, and SplitMetrics Acquire’s custom product page experiments show how each page performs on paid traffic, so every creative decision is backed by data. 

What should app marketers prepare as the App Store creative assets launched?

The App Store creative assets are a new category of images and videos for brand messaging, seasonal offerings and new content. You can upload them in App Store Connect now and use them on your organic listing and later — in Apple Ads. They complement the screenshots and app previews already on your product page, and they don’t have to show the app in use.

The best use of this week is to get ready, so approved assets are live when Apple Ads opens to them. SplitMetrics advises uploading ahead of the date you want a campaign to run, and leaving time for both reviews.

Audit what your current screenshots carry

Check each screenshot for awards, rating badges and call-to-action lines. SplitMetrics advises against using the entire asset to highlight general accolades or call-to-action statements. In our reading, the product page header gives promotional messages their own place, so screenshots can go back to showing the app in use. Then list the brand and campaign creatives you already have, and check which of them meet the asset best practices.

Brief each placement separately

Each placement does a different job, so each gets its own brief, with its own message and metric:

• Search results asset: wins attention and shows the app matches the search. Relevance to the query is the goal. 
• Product page header: opens the product page, where the screenshots back up the promise.
• Today tab asset (coming later): builds brand affinity with a distinctive set of images. It uses images only. Video can be used in search results ads, not on the Today tab.

Design for silence and for localization

Videos can be uploaded with audio, but audio will not play in ads. Build every video so it works silent, with captions and text overlays carrying the message. Text in a creative asset can be localized. Upload a localized version for each market, plus a version without text to cover countries and regions where you have no localized text.

Give each custom product page a purpose before it gets a header

Each custom product page can carry its own header, and you can use a different creative asset for each. That doesn’t mean every page needs one. Start with the pages that already get traffic from a campaign. Give each page one purpose, one traffic source and one success metric.

When an asset is used in an ad, keep the journey consistent: the same visual on the ad and on the page header, then a deep link to the right place in the app. Two details to plan for. If you add an ad deep link in Apple Ads, it serves instead of the deep link set on the custom product page. And to link an asset to specific keywords, all of those keywords need to sit in the ad group the asset is linked to.

Plan for two reviews, each with its own owner

Creative assets go through two separate reviews:

1. App Store review in App Store Connect. The first approval takes about the same lead time as an app version. Assets can be submitted on their own through Asset Library, without an app update. After that, an approved asset can go up and come down on the product page header and in search results with no new submission.
2. Apple Ads review of the ad. After you build an ad with a creative asset, Apple Ads reviews the ad against its own guidelines before it can run.

Name one owner for each review. Then count the lead time back from the date you want the creatives live.

Shape your first header test before production starts

Product page optimization lets you test alternative headers against your current page. Each test runs up to 3 treatments against the original for up to 90 days. SplitMetrics recommends testing your app’s logo, its core value or a new feature.

To read the same header on paid traffic, run it as a custom product page test with CPP Experiments in SplitMetrics Acquire, which compares page variants on paid Apple Ads traffic using Switch, Parallel or Dayparting rotation methods. You see the full funnel, from tap-through and download rate to trial start rate, cost per trial and ROAS, so a header that lifts taps but not installs or subscriptions doesn’t pass as a winner.

Video doesn’t win automatically. Simply Piano tested adding an app preview video as the first asset, and the original page won by 3%.

Where should the optimization of app creatives start?

The optimization of app creatives should start small, with one audience and one asset. Anastasia Voronina, User Acquisition Manager at SplitMetrics, recommends this sequence:

One page can be enough to prove the approach. SplitMetrics Growth Services team rebuilt a single custom product page around a clearer value proposition, real social proof and benefits in place of feature lists. Measured against the version it replaced, tap-through rose by 30%, download rate lifted by 7% and cost per trial dropped by 27%. That result came from one page and one test.

How SplitMetrics supports App Store creative assets

Creative assets give you more to design, more to localize and more to test. SplitMetrics helps with each.

Never run out of creatives to test with Lyra. Testing needs fresh variants and Lyra delivers them without adding headcount or agencies. Build your workflow once in one shared canvas, from script to final cut. Then turn it into 10x ad variations with new hooks, characters or voiceovers, resized and localized in a single run. Your Brand Kit keeps every version on brand and you can edit every single step without starting over. 

Run custom product page optimization end to end with Acquire. The full custom product page workflow lives in one system. See which headers and keywords your competitors use, then test your variants on Apple Ads traffic with CPP Experiments tracking the full funnel impact from tap-through to ROAS. When a winner is found, activate it at the right moment with the CPP Scheduler.

What to fix first to speed up app creative production

App creative production gets faster when creatives run as a repeatable process instead of one-off requests. A brief with one success metric, one owner with clear approval roles and tests judged with the right method cut down the rework between teams.

App Store creative assets add new creatives to that process, and uploads are open now. Teams that fix the brief, the ownership and the testing first will be ready to use them when Apple Ads opens to them. The checklist turns every step in this guide into a task your team can work through.

Everything Apple Ads, in one place.
