How to Make a Mobile App Demo Video From a Phone Screen Recording (2026)

You built an app, and now a client, a tester, an investor or a landing page visitor needs to see it working. The fastest honest answer is a short video of the real app, recorded on a real phone.

Both Android and iPhone have a screen recorder built in. What makes the difference is the preparation before you press record and a few decisions after it.

This guide is for indie developers and small teams showing an Android or iOS app to other people.

#The short version

1. Pick one flow a viewer should see, such as sign up, create the first item, and see the result.
2. Prepare the phone: Do Not Disturb on, battery charged, demo account with believable data, default text size.
3. Turn on touch indicators on Android (Show touches or Show taps). iPhone has no built-in equivalent, so you will explain taps in narration or captions.
4. Record with the built-in recorder: Quick Settings on Android, Control Center on iPhone.
5. Tap slowly and pause for a second after each screen change.
6. Trim, then add narration and captions, either by hand or with a tool.
7. Export for where it will play: portrait for app stores and social, a portrait video on a background for 16:9 pages and YouTube.

#Step 1: Decide who is watching

A client wants to see that the agreed flow works. A tester wants to know exactly what to tap. An investor wants to know what the app does and why anyone would use it. Write one sentence: who is watching, and what should they know afterwards. Then pick the one flow that answers it. If you have three flows to show, make three short videos. Our guide to making a product demo video goes deeper into planning a click path, and most of it applies to taps as well.

#Step 2: Prepare the phone

A phone recording shows everything, including the status bar and every notification.

• Turn on Do Not Disturb. A message preview sliding down mid-demo is distracting and can leak personal information. Turn it on in Control Center on iPhone or in Quick Settings on Android.
• Charge the battery. A red battery icon in the corner looks careless.
• Tidy the status bar. Turn off anything that adds icons you do not need, like a VPN or a hotspot. Connect to Wi-Fi so the signal looks normal and screens load quickly.
• Use a demo account with realistic data. An empty list looks broken. A list of "test1, test2, asdf" looks unfinished. Create believable, fictional names, amounts and photos. Never record a real customer's data.
• Reset text size and display zoom to default unless you want to show accessibility support. Larger text can change your layout, so the video may not match what most users see.
• Run through the flow once without recording. Dismiss first-run permission prompts, cookie banners and "rate this app" dialogs before you start, unless they are part of what you are showing.

#Step 3: Record on Android

Android's built-in screen recorder lives in Quick Settings. On a Pixel, Google's screen recording help page describes it like this:

1. Swipe down twice from the top of the screen.
2. Tap Screen record. You may need to swipe sideways to find it. If it is not there, open the Quick Settings edit controls and drag Screen record in.
3. Choose what to record, and whether to record audio and show touches on the screen.
4. Start. Recording begins after a countdown.
5. To stop, swipe down again and tap the screen recorder notification.

Recordings land in the Photos app under Collections, On this device, Movies. Google notes that on Pixel some of these steps only work on Android 11 and later.

The name and location of the tile vary by phone maker, and some makers add their own recorder options. If you cannot find it, search your phone's Settings for "screen record" or check the maker's help pages.

#Show your taps on Android

Viewers cannot see your finger. On Android you can fix that two ways. The recorder's own show touches option, mentioned above, is the simplest. There is also a system setting: enable Developer options by tapping Build number seven times (on a Pixel it is under Settings, About phone), then turn on Show taps in the Input section. A circle appears under your finger and follows it.

#Step 4: Record on iPhone

On iPhone, screen recording is a Control Center control. Apple's iPhone User Guide gives these steps:

1. Swipe down from the top-right corner to open Control Center.
2. Tap the Screen Recording button and wait for the three-second countdown.
3. Swipe up to dismiss Control Center, then use your app.
4. To stop, tap the red indicator at the top of the screen (on phones with the Dynamic Island, tap the red circle) and tap Stop.

Recordings are saved to Photos. In Collections, scroll to Media Types and tap Screen Recordings.

If you do not see the Screen Recording control, add it. On current versions of iOS you do that inside Control Center itself: open it, start editing, tap Add a Control and pick Screen Recording (Apple's Control Center guide). On iOS 17 and earlier, the same thing is in Settings > Control Center.

To record your voice, touch and hold the Screen Recording button, tap Microphone to turn it on, then tap Start Recording. Apple's support article on screen recording describes the same long-press.

iPhone has no system setting that draws a circle where you tap. Keep that in mind when you plan narration: say what you are tapping, or let captions say it.

#Step 5: Pace your taps

Most phone demos are too fast. You know the app, so your thumb moves before the viewer has read the screen. A few habits help:

• Pause about a second after each tap before doing anything else. The screen change needs time to register, and you get clean cut points.
• Scroll slowly and stop on purpose. Fast flicks blur text and make viewers dizzy.
• Type at a steady pace. If you mistype, stop, wait, clear the field and type it again. A clean retake is easier to cut than a messy correction.
• Record short takes. One flow per recording. If something goes wrong at second 40, you redo 40 seconds, not five minutes.

For more on pacing, zoom and captions, see our demo video best practices.

#Step 6: Portrait or landscape

Record in the orientation people use your app in, which for most phone apps is portrait.

Where each orientation fits:

The awkward case is the wide one. A portrait recording in a 16:9 player gets black bars on both sides. The usual fix is to place it in the middle of a 16:9 frame on a solid colour or soft pattern.

#Step 7: Keep it short

There is no magic length, but a phone flow is usually short. Signing up, creating something and seeing the result can often be shown in well under a minute once dead time is cut. Trim the loading spinners, the hesitations and the bit at the start where you swipe Control Center away.

Store limits are a useful guide even off the stores: Apple's app previews can be at most 30 seconds, and Google Play autoplays only the first 30 seconds of a preview video.

#Step 8: Add narration

A silent tap-through is fine for testers. Almost everyone else needs to be told what they are seeing.

Talk while you record. Quick, but talking and tapping at once is hard, and every stumble means a retake.

Record silently and add voiceover afterwards. Write one line per step, record it, and line it up in an editor. Better narration, but syncing takes time. Our post on adding an AI voiceover to a screen recording covers this route.

Captions only. For landing pages and store previews that autoplay muted, on-screen text often does more than voice. Apple notes that app previews play muted by default and suggests using copy to add context.

Whatever you choose, keep the lines short and concrete: "Tap the plus button to add a habit" beats "Here you can see our intuitive habit creation experience."

#Where Nook fits

This is the part Nook does for you. Nook does not record your screen. You record with the built-in recorder as described above and upload the file: MP4, MOV or WebM, up to 15 minutes, and portrait is fine.

Nook finds each tap and screen change, writes a line of narration per step from what is on screen, and voices it. You can use an AI voice in 15 languages, your own voice, or captions only. It adds captions, and it can place a portrait recording on a coloured background so you get a 16:9 video for YouTube or a landing page. You can add intro and outro cards in your colour and background music. Alongside the video it writes a step-by-step guide with screenshots, which you can export as PDF, Word or Markdown, useful for testers and client handovers.

#Step 9: What the app stores ask for

If the video is going on a store listing, the store's rules come first. Keep these brief and check the official pages before you upload, because they change.

#Google Play preview video

On Google Play, the preview video is a YouTube link, not a file upload. According to Google's preview assets help page:

• Paste the URL of the individual YouTube video, not a playlist or channel, and without extra parameters like timecodes.
• Turn off ads (monetization) on the video.
• Set it to public or unlisted, not private. Do not use an age-restricted video, and make sure embedding is allowed.
• Only the first 30 seconds autoplay. Google recommends keeping it short.
• Landscape and portrait are both supported. Avoid black bars on a portrait video.

#App Store app previews

Apple calls these app previews, and they are uploaded as files in App Store Connect. From Apple's app previews page and the App Store Connect specifications:

• Up to three previews per language, each 15 to 30 seconds long.
• Accepted formats are .mov, .m4v and .mp4 (H.264), or .mov with ProRes 422 HQ, up to 500 MB, at most 30 frames per second.
• Previews are device-specific. For the large iPhone sizes, the accepted resolution is 886 x 1920 in portrait or 1920 x 886 in landscape. Check the specifications page for other devices.
• Previews must show only content from within the app. Apple says not to film people holding the device or fingers tapping the screen.
• They autoplay muted, so on-screen text matters. Avoid prices and dated references like "new for spring."
• If features need an in-app purchase, a subscription or a login, you must disclose it.

So a narrated 16:9 demo for your website and a store preview are usually two different exports from the same recording.

#FAQ

#How do I make a demo video of my app?

Record one flow with the phone's built-in recorder after turning on Do Not Disturb and setting up a demo account. Tap slowly, trim dead time, then add narration or captions.

#How do I show taps in an Android screen recording?

Turn on the recorder's show touches option before you start, or enable Developer options and turn on Show taps under Input. A circle then follows your finger in the recording.

#Can I show taps on an iPhone screen recording?

iPhone does not have a built-in setting for this. Describe each tap in narration or captions, or add highlights while editing.

#How long should a mobile app demo video be?

As short as the flow allows. For store listings, Apple app previews must be 15 to 30 seconds, and Google Play autoplays only the first 30 seconds, so make the start count. For clients and testers, the length of one flow with the waiting cut out is usually right.

#Should my app demo video be portrait or landscape?

Usually portrait, as people use the app. For YouTube, decks and wide players, place the portrait recording on a coloured background in a 16:9 frame instead of leaving black bars.

#Can Nook record my phone screen?

No. Nook works with a recording you already have. Record with the phone's built-in recorder, move the file to your computer, upload it, and Nook adds narration, captions, an optional 16:9 background, intro and outro cards, and a step-by-step guide.

#How much does Nook cost for an app demo?

Your first video is free, up to one minute and watermarked. After that it is $9 per video, or Pro at $19 a month for 10 videos. Prices are lower in many countries, such as India and Brazil.

#Wrapping up

A good mobile app demo is mostly preparation: one flow, a quiet phone, believable data and slow taps. Then shape it for where it will play: muted and captioned for stores and landing pages, narrated and 16:9 for clients, investors and YouTube. If you would rather not do the narration, captions and framing by hand, you can upload the recording to Nook and get the video and a written guide back.
