How to Make an App Demo Video With Your Mac and iPhone
A practical app demo video workflow for indie developers using a Mac, iPhone camera, screen recording, and lightweight edits.
Short answer
A good app demo is not a tour of every feature. It is a tight proof that the app solves one valuable problem.
Key takeaways
- Start with the use case, not the feature list.
- Record face, screen, and voice together when possible.
- Edit for momentum: remove setup time, dead air, and repeated clicks.
Write the promise first
Before recording, write one sentence: after watching this video, the viewer should believe the app can do what?
That sentence controls the demo. If a feature does not support the promise, leave it out.
Capture the right sources
For a founder or product demo, the strongest setup is usually screen plus face plus voice. The screen proves the product, the face builds trust, and the voice keeps the viewer oriented.
Splonk is built for that capture pattern: Mac screen, iPhone camera, microphone, then a lightweight timeline for edits.
Use a three-part structure
Open with the painful before state. Show the product doing the core action. End with the finished outcome.
Do not narrate every click. Narrate decisions and outcomes. Viewers can see the clicks.
Edit ruthlessly
Cut loading pauses, failed clicks, repeated setup, and every sentence that explains what the viewer can already see.
If the video feels slow, it is probably because the editor kept context that mattered during recording but not during watching.
FAQ
How long should an app demo video be?
For launch pages and social posts, 30 to 90 seconds is usually enough. For a walkthrough, make chapters rather than one long unfocused recording.
Should I show my face in an app demo?
If trust matters, yes. A small iPhone camera view can make the demo feel more human without hiding the product.
