How to Make a Product Hunt Launch Video
Seven guides rank for this and all seven treat the video as the hero asset. On Product Hunt it is not — the gallery is, and the difference changes what you build first.

Product Demo Animation: When to Animate vs Record
Every page ranking for this term is published by a studio that sells animation, and every one of them reaches the same conclusion. Here is the case for the other answer.

Record Camera, AR and Scanner Flows in the iOS Simulator with RocketSim
If you’re shipping a SwiftUI feature that uses the camera (AR, QR/barcode scanning, photo picker) and you want a Product Hunt launch video or App Store…

How to Create a Demo Video for an App in Under an Hour
Every guide on this topic lists the same six stages and none of them tells you what a stage costs. Here is the same job with a clock on it, and a rule for what to drop.

App Store Preview Video Examples From Apps That Rank
Every gallery of preview examples has the same flaw: you cannot watch a single one of them in a browser. The reference set is already in your pocket.

Mobile App Promo Video: Formats, Length and Aspect Ratios
Two of the places this video goes can reject the file. The rest just bury it. Build for the two, crop for the rest, and the afternoon stops being an afternoon.

App Preview vs Screenshots: What Converts Better on the App Store
Every page ranking for this question quotes a conversion percentage from somebody else's app. Apple ships a free test that answers it for yours, and almost nobody mentions it.

App Demonstration: How to Show Your App to Anyone
The phrase covers three unrelated jobs. The one that goes badly is almost always the one you prepared for as though it were a different one.

15 Product Demo Video Examples Worth Copying

Shipping a new iOS build is satisfying.

How to Record a SwiftUI App Demo Video on Mac (Using Only Free Tools)
SwiftUI developers ship fast. Your demo videos should keep up.

Every guide optimises the first take. The take that decides whether this was worth doing is the fifth one, three months from now, after the UI moved.

App Store Screenshot Dimensions and Requirements (2026)
Nine near-identical pages publish the same table. None of them tell you how to originate a pixel-exact file, which is the only part that ever goes wrong.

SaaS Demo Video: How to Make One That Sells
Most guides assume you can already record clean footage and that the output is one file. Both assumptions are wrong, and both are why the video never ships.

How to Make an App Promo Video That Converts
Three destinations, three sets of rules, one take. Decide where the video is going before you write a word of it, because one of the three destinations will reject what the templates make.

How to Market an App: The Solo Developer's Playbook
Your marketing budget is hours, not dollars. The order of the steps decides the outcome more than the list of channels does — and the first hours belong to your product page.

App Store Preview Video: Specs, Sizes and Requirements
Apple publishes the numbers. Nobody publishes the arithmetic — no iPhone screen is shaped like 886 x 1920, and the popular fix for that is itself a rejection reason.

How to Make an App Demo Video (Without Recording One)
Every guide has one answer to "where does the footage come from." There are three, and which one you pick decides how well your cuts land.

What Is a Product Demo Video? Types, Length and Examples
Most guides sort these videos by tone. Sort them by what footage you start from instead — that predicts the effort, the price, and the pain when the UI changes.

What Is an AI App Demo Video Generator?
Sort the category by one question — when the video plays, what is on screen? An AI presenter, your screenshots, or your app actually running. That answer decides the rest.
