The Drunk Grandmother Test: How to Write Value Props That Actually Work

TL;DR

If a tired person at 4 a.m. can’t immediately understand what problem you solve, you’ve already lost them. Most app listings hide behind jargon and list features instead of solving one clear problem. Attention is the scarcest resource in the App Store—strip the jargon, pick one problem, make your value obvious before anyone has to think.

Who This Is For

B2B SaaS founders and Shopify app developers who wonder why their listing gets views but no installs.

The Core Problem

You’re writing for yourself, not for exhausted merchants scrolling at 11 p.m. trying to fix a specific pain. They won’t decode your feature set—they’ll bounce.

Open your app listing.

Now imagine your drunk grandmother logs in at 4 a.m.

Can she understand what you do in 5 seconds?

If the answer is no, you’re losing merchants before they even scroll.

The Test That Reveals Everything

I use this test with every Shopify App Audit:

“If your drunk grandmother can’t log in at 4 a.m. and immediately understand what you do, then it’s not good enough.”

Harsh. But accurate.

Most app listings fail this test.

They hide behind jargon. They list features instead of solving one clear problem. They assume merchants will read three paragraphs to figure out what problem this solves.

They won’t.

Why 4 A.M. Matters

The drunk grandmother isn’t literal.

She’s a stand-in for your actual customer at their worst moment.

A burned-out merchant scrolling the App Store at 11 p.m. after a long day.

Someone who just got a complaint about their checkout process and needs to fix it now.

A founder with 47 browser tabs open, trying to solve one specific problem before they can go to bed.

They’re not in learning mode. They’re not in exploration mode.

They’re in “does this solve my problem or not?” mode.

And they’re giving you about 5 seconds to answer that question.

What Happens in Those 5 Seconds

They land on your listing. First thing they see is your title and subtitle.

If those don’t immediately communicate what problem you solve, they’re already scrolling to the next result.

They might glance at your first screenshot. If it’s full of UI without context, it doesn’t help.

They might read your first sentence. If it starts with “Our platform leverages advanced technology to…” they’re gone.

Five seconds. That’s all you get.

If you haven’t communicated clear value in that window, you don’t get a second chance.

The next app in the search results does.

Why Most Listings Fail This Test

Because founders write listings for themselves, not for their customers.

You know your product intimately. You understand every feature. You appreciate the technical complexity. You’re proud of what you built.

So you write about features. You explain how it works. You list capabilities.

“Advanced customization options.”

“Seamless integration with your existing workflow.”

“Powerful analytics and reporting.”

All technically accurate. All completely useless to someone trying to figure out if you solve their problem.

Because they don’t care about your features. They care about their pain.

What Clarity Actually Looks Like

Clear positioning answers one question instantly:

“What problem does this solve for me?”

Not “what does this do?” Not “how does this work?” Not “what technology does this use?”

What problem does this solve?

If you can’t answer that in one simple sentence using words a tired person would understand, your positioning isn’t clear yet.

“See which ads actually drive revenue” is clear.

“Multi-touch attribution tracking” is not.

“Get customers to spend more without annoying them” is clear.

“Intelligent cross-sell optimization engine” is not.

“Add revenue at checkout without slowing it down” is clear.

“Checkout upsell widget with advanced customization” is not.

Notice the pattern. Clear positioning describes the outcome. Unclear positioning describes the mechanism.

The Jargon Trap

Industry jargon is invisible to people inside the industry.

You use these terms every day. Your team uses them. Your competitors use them. So it feels normal.

But merchants don’t think in your terminology.

You think “attribution.” They think “which ads are actually working?”

You think “cross-sell optimization.” They think “how do I get customers to buy more stuff?”

You think “checkout upsell.” They think “why isn’t anyone adding to their cart?”

When you lead with your internal language instead of their actual thoughts, you create friction.

They have to translate your words into their problem. That translation takes mental energy.

And in those 5 seconds, they don’t have mental energy to spare.

How to Pass the Drunk Grandmother Test

Step 1: Strip the jargon

Take your current app listing. Read your title, subtitle, and first paragraph out loud.

Every time you use industry terminology, replace it with plain language.

“Multi-channel inventory synchronization” becomes “Stop overselling products.”

“Advanced segmentation engine” becomes “Send emails to the right customers.”

“Intelligent recommendation algorithm” becomes “Show products people actually want.”

If your grandmother wouldn’t understand the word, don’t use it.

Step 2: Pick ONE problem

Your app might solve multiple problems. Your listing can’t communicate multiple problems in 5 seconds.

Pick the one problem that matters most to your best customers.

The problem they had before they found you. The pain point that made them search for a solution.

That’s your positioning.

Not all the things you can do. The one thing merchants care about most.

Step 3: Make it obvious

Your value should be clear without explanation.

No “learn more to understand how this works.” No “read our docs to see the benefits.”

Just immediate, obvious value.

If someone lands on your listing and thinks “oh, this might solve my problem,” you passed.

If they think “I’m not sure what this does,” you failed.

What This Looks Like in Practice

Here’s a real example.

An app that did customer data synchronization across platforms.

Their original positioning: “Unified customer data platform for Shopify merchants.”

Technical. Accurate. Completely unclear to their actual customers.

The problem their customers actually had? They were manually copying customer information between systems and making mistakes.

New positioning: “Stop copying customer data by hand.”

Same app. Same features. Completely different clarity.

A tired merchant at 11 p.m. who just spent an hour manually updating customer records sees that title and thinks “yes, that’s exactly my problem.”

They don’t need to understand what a “unified customer data platform” is. They just need to know you’ll stop the manual work.

When Clarity Feels Too Simple

Founders resist this advice because clear positioning feels too simple.

“But our product does so much more than that.”

“We don’t want to limit ourselves to one use case.”

“What about all our other features?”

Here’s the thing: Clear positioning isn’t about limiting what your product does. It’s about making it easy for customers to understand why they should care.

Once they install your app because it solves one clear problem, they’ll discover all your other features.

But they won’t install at all if they can’t figure out what you do.

Better to be clear about one thing than vague about everything.

Testing Your Own Positioning

Pull up your app listing right now.

Read your title out loud.

Would someone exhausted at midnight immediately know what problem you solve?

If the answer is anything other than “obviously yes,” you have work to do.

Show your listing to someone outside your industry. Give them 5 seconds. Ask them to explain what your app does.

If they can’t, neither can your customers.

And if your customers can’t understand what you do, they won’t install.

No matter how good your product is.

Frequently Asked Questions

Won’t oversimplifying make us sound less sophisticated?

Clarity and sophistication are not opposites. The most sophisticated companies explain complex products in simple language. If you can’t explain it simply, you don’t understand it well enough yourself.

What if our product really does multiple things equally well?

Then pick the one thing your best customers hired you to do first. You can mention other capabilities later, after you’ve earned their attention with clear value.

How do I know which problem to focus on?

Ask your most successful customers: “What problem were you trying to solve when you first installed our app?” That’s your positioning. Not what you think they should care about—what they actually cared about.

Doesn’t this approach ignore our technical differentiators?

Technical differentiators matter after someone understands what you do. But if they bounce before reading your description, your differentiators never get a chance to matter. Lead with clarity, follow with sophistication.

What if our competitors are using the same simple positioning?

Then you differentiate on specificity, not jargon. “Reduce checkout abandonment for stores with subscriptions” is clearer than “reduce checkout abandonment” even if both are simple.

Key Takeaways

The 5-second rule: If a tired person at 4 a.m. can’t understand what you solve, you’ve already lost them. Attention is your scarcest resource.
Jargon kills conversions: Merchants don’t think in your industry terminology. Translate technical features into clear outcomes they recognize.
One problem, clearly stated: Your app might do many things, but your listing can only communicate one clear value in 5 seconds. Pick the problem that matters most.
