01 / Creative research

Turn the unknowns into a research plan.

01

Check the acquisition promise

Read the store headline, screenshots and description. What problem is the app promising to solve?

Study the storefront ↗
02

Look for ad evidence

Explore apps with direct store-link matches. Compare their hooks and formats without assuming the same approach works here.

Browse observed advertisers ↗
03

Separate demand from paid growth

Store rankings and revenue estimates describe market context. They do not establish ad spend, conversions or ROAS.

Review the market context ↗

02 / Storefront & product

Where the click lands.

Study the product story and store experience behind the acquisition funnel.

Exactly what I was looking for

Simple, very very simple my only complaint is theres not enough content to really justify the app but I still like it

Is what it says, elementary

Elementary SQL, very elementary. If you've written SQL on the job anywhere chances are this will teach you little to nothing. It's very bland though but is focused on simple presentation. If your learning or taking a class, the visuals are nice for things like outer joins. Good start!
