How To Make High-Converting App Store Screenshots For Your App (7 Principles)

Over the past year, at Scrnsht Studio we've been obsessed with one thing: designing high-converting App Store screenshots.

Every week, we've tested new ideas, redesigned concepts and spent way too much time trying to understand what actually makes someone install an app.

Some things worked.

Others didn't.

But over time, the same patterns kept showing up.

These are the 7 principles we now use on almost every project ↓

---

1. Start with a clear value prop

Screen 1 = value prop

The simpler and clearer it is, the easier it becomes for users to understand why your app is worth downloading.

Finding the right value proposition isn't something you can guess. It comes from understanding your users, their pain points and how your app is different from the alternatives.

That's why we never start with design. We start with research.

2. Sell the outcome, not the feature

People rarely care about features.

They care about what those features allow them to achieve.

Nobody wants an AI calorie tracker. They want to lose weight. Nobody wants a meditation app. They want to feel calmer.

Every concept starts with the same question:

What is the user hoping to achieve with this app?

Once we have the answer, everything else becomes much easier. The messaging, the visuals and the story should all reinforce that same outcome across every screenshot.

3. 1 screenshot = 1 message

The strongest concepts are often the simplest.

Every screenshot should have one primary message. Everything else should only exist to support it.

That doesn't mean you can't include secondary information. But there should always be one idea that stands out more than the others.

If users remember one thing after looking at your screenshot, you did your job.

4. Make the idea obvious

People always look before they read.

That's why we spend so much time looking for a visual hook before writing the headline. If a concept relies entirely on copy to be understood, there's usually a stronger visual idea waiting to be found.

One exercise we often do is to hide every headline and every piece of copy. If we can still roughly understand what the app does, we know we're heading in the right direction.

The copy shouldn't explain the concept.

It should simply make it even clearer.

5. Humanize the experience

Our eyes are naturally drawn to people.

When someone is comparing multiple apps, a face, a hand or a real-life situation will often grab their attention faster than another UI mockup.

That's why we try to integrate human elements whenever they make sense.

They make the concept feel more relatable and help users picture themselves using the app, instead of simply looking at it.

Across the projects we've worked on, we've noticed that human-centered concepts often perform better.

6. Build trust

No matter how good your app is, people will always have one question in mind:

Can I trust this?

Trust is built through small signals: ratings, reviews, awards, download numbers, press mentions or trusted brands.

These details are often treated as an afterthought, but we've found they can completely change how an app is perceived.

If you don't have these yet, don't try to fake them or make exaggerated claims. Trust is also built through honesty and credibility.

The more credible your app feels, the easier the decision becomes.

7. Keep your copy simple

Founders often try to fit too much into a single headline.

In reality, the best copy is usually the shortest.

Simple words are easier to understand, easier to remember and much easier to scan. More importantly, shorter copy lets you make your headlines much bigger.

And on the App Store, size matters.

A bold, oversized headline is far more likely to catch someone's attention than a paragraph squeezed into two lines.

Don't try to sound clever or technical. Use the words your users would naturally use.

Knowing what makes a great screenshot is one thing.

Turning those ideas into a concept that fits your product is another.

That's where we can help.
