How to Create a Mobile App Walkthrough From Screenshots

To create a mobile app walkthrough from screenshots: screenshot every screen of one task on a phone, name the files in order, upload them, and on each screen mark where to tap and write one short instruction. You end up with a clickable sequence that opens from a link in any phone browser. Nobody installs anything, and you never touch a video editor. The steps below cover capturing clean screens, ordering them, writing instructions people actually follow, and testing before you send it.

This approach suits products that live on phones: field service, maintenance, inspections, delivery, site management. If your product is a web app, you can record the flow with a browser extension instead. For native apps, screenshots are the most practical way in.

1. Pick one task and one role

Before you take a single screenshot, write down the task in one sentence, from the user's side:

• "A technician closes a work order."
• "A supervisor approves a permit."
• "A new inspector submits their first checklist."

One task, one role. If the workflow passes between people, as most field workflows do, make one walkthrough per role. A technician doesn't need to see the approval screens, and a supervisor doesn't need the scanning steps. Shorter walkthroughs get finished; long ones get abandoned halfway.

2. Capture the screens on a real phone

Use a test account with realistic data. Screens with an empty list or "Test 123" everywhere make the walkthrough harder to follow, because the viewer can't tell what they're looking at.

• Android: press Power + Volume Down together.
• iPhone with Face ID: press Side + Volume Up.
• iPhone with a Home button: press Side (or Top) + Home.

Both save PNG files. Take one screenshot per screen state, including the in-between ones people miss: the dropdown open, the confirmation dialog, the success message. If a step needs the user to scroll, take two screenshots, one before the scroll and one after, rather than trying to fit everything into one.

3. Clean up and name the files

Move the screenshots to your computer and do three things:

1. Delete duplicates and mistakes. If you tapped the wrong thing and went back, remove those screens.
2. Hide anything private. Worker names, phone numbers, customer addresses. You can blur these inside most walkthrough tools after uploading, so you don't need a separate image editor.
3. Rename in order: 01_jobs.png, 02_job_detail.png, 03_checklist.png. Use two digits (01, not 1) so 10 doesn't sort before 2.

Good walkthrough tools sort uploads by file name, so the names become the step order.

4. Upload and mark each tap

Upload all the files at once. Then go through the screens one at a time and, on each:

• Draw the tap target over the button, row or field the user should tap. Make it a little bigger than the element so it's easy to hit with a thumb.
• Write one instruction that says what to do and why, in the user's words.

Some screens don't need a tap (a summary, a "you're done" screen). Leave those without a target. A good player shows a plain Next button on them, so the viewer can carry on.

5. Write instructions people actually follow

This is where most walkthroughs go wrong. The tap target already shows where. The text's job is to say what and, when it matters, why.

The rules:

• Start with a verb. "Scan," "Pick," "Confirm," "Open."
• One action per screen. If you need two sentences, you probably need two screens.
• Name the thing on screen, in the same words the app uses, so the viewer knows they're in the right place.
• Add the reason when skipping it would cause harm. "Apply your lock and tag before you start" is a safety step; say so.
• Write in the language your users work in. If the crew works in Hindi or Tamil, write the walkthrough in Hindi or Tamil. A separate walkthrough per language is fine.

6. Test it on a phone, not your laptop

Open the share link on an actual phone, ideally a cheap Android rather than your own flagship, and go through it the way a new user would:

• Can you hit every tap target with your thumb?
• Is the instruction readable without zooming in?
• Is there any screen where you weren't sure what to do next?

Then hand the phone to someone who has never used the app and watch without helping. Every place they hesitate is a screen to fix.

7. Send it where your users already are

For frontline teams that usually means a chat group, not an email or an LMS login. Paste the link with one line of context ("Go through this before Monday's go-live, takes 3 minutes"). See how to share software training on WhatsApp for message templates and what to avoid.

Keeping it current

When the app changes, replace only the screens that changed and leave the rest. That's the main advantage over video: a new button color costs you one screenshot, not a re-shoot.

If you're rolling out an app to field teams, the field teams walkthrough guide shows how this fits a go-live, with one walkthrough per role.
