TL;DR
Prep is filling the app with real-looking data and polishing the screens before you capture. A populated, tidy app screenshots far better than the same app shown empty.
The same app can look bare or genuinely useful depending on how it is prepped before you capture screens. Prep is the cheap, fast work you do in Expo before the screenshots come out. It is often the difference between a listing that converts and one that looks half-built.
Prep before you capture
- 1Fill it with data: add realistic entries so screens are not empty.
- 2Fix the small stuff: line up spacing, fonts, and any cut-off text.
- 3Clear placeholders: remove lorem ipsum and test labels.
- 4Set the scene: open the screen to the most impressive real state.
- 5Tidy the frame: hide dev banners and pick clean, on-brand content.
A ten-minute fill-in can noticeably change what an app looks worth. Empty screens make a browser assume the app is thin or unfinished. A tracker with real entries or a planner with a full day tells them it actually does something, which lifts your download rate.
Match the effort to the launch
You do not need a studio setup for a first app. Scale the effort to what you are shipping. A simple utility just needs clean, filled screens. A more visual app earns a little care with realistic sample content that shows it at its best.
Do not fake the app. Prep makes it look its honest best, not better than it is. Fill it with realistic data and pick strong screens, but every screenshot still has to match the real build, since reviewers compare them and misleading shots get rejected.
Common questions
What does preparing an app for screenshots mean?
Filling it with realistic data, polishing the screens, and opening it to its most impressive real state before you capture. Prep makes an app look useful and cared for, which lifts your download rate on the listing.
How much time should I spend prepping?
Scale it to the launch. A quick data fill and tidy is enough for a simple utility, while a visual app earns more care with realistic sample content. Do not overbuild a fake demo for a tiny first app.
Does realistic data really change conversion?
Often, yes. Empty screens make browsers assume the app is thin, while populated screens show it doing its job. A ten-minute fill-in can noticeably shift how useful the app looks in your screenshots.
Should I show the app in active use?
Yes. Capture it the way someone would have it after real use - a streak going, a list filled, a chart with data. Include those alongside clean shots of the core screens so browsers see the app working.
Can prep hide an unfinished app?
It should not. Prep shows the real app at its honest best, but every screenshot must match the actual build. Faking screens you have not built gets caught in review and leads to a rejection.
Do I need special tools to prep the app?
No. Use Expo to run your real app, add realistic data by hand, and capture the screens. The point is a filled, tidy app and clean content, not a decorated studio set. Simple and real beats staged and fake.
