Which App Demo Tools Run Locally Without Uploading Your Code

If you care about keeping your app builds and UI flows off the cloud, your choice of demo tooling matters.

This tutorial focuses on Screen Studio for macOS — a native, local‑first app demo recorder — and shows you how to:

• Download Screen Studio safely
• Handle macOS permissions for screen recording
• Complete the login setup and activation
• Troubleshoot common install issues
• Verify that capture is working correctly, without surprise uploads

Along the way, you’ll see how Reely slots in as an AI‑native, app launch video generator that also renders locally and plugs into agent workflows for mobile developers.

Local‑First App Demo Tools: Screen Studio vs Cloud Alternatives

Before we dive into the tutorial, it’s useful to understand where Screen Studio sits.

• Screen Studio runs as a native macOS app and processes recordings locally by default.
  • Its privacy policy states that recordings are stored as .screenstudio project files on your device, and that "screen recordings will only be uploaded" when you explicitly generate a share link.[^screenstudio-privacy]
  • This makes it one of the most clearly documented local‑first demo tools.
• Clueso, by contrast, is a cloud‑first tool.
  • Its FAQs note that you record in a Chrome extension or upload a video, and the platform then processes that uploaded recording into a video and article.[^clueso-faq]
• Reely sits in a third category: a local macOS motion studio + AI agent integration built specifically for mobile app launch videos.
  • It uses the iOS Simulator and renders on the Mac, so your app build doesn’t have to leave your machine.[^reely-about]

If you’re a developer who wants no surprise uploads and app previews that stay close to code, Screen Studio and Reely are both solid fits. This tutorial will walk Screen Studio step‑by‑step, then show where Reely can take over for launch‑ready promos.

Screen Studio macOS permissions

Screen Studio needs a handful of macOS permissions to record and edit app demos properly:

• Screen Recording — to capture the display
• Accessibility — for features like smooth cursor movement
• Microphone — if you want voiceover
• Camera — if you plan to include webcam footage

Missing any of these can cause broken recordings or a blank preview.

We’ll walk through granting these permissions during install and how to fix them later if something goes wrong.

Step 1: Screen Studio download and install macOS

Screen Studio is macOS‑only, with specific system requirements.[^screenstudio-download]

1.1 Check macOS and hardware requirements

According to the official guide:[^screenstudio-requirements]

• Operating system
  • Recommended: macOS Ventura 13.1+
• Hardware
  • Apple Silicon Macs (M1/M2/M3) are fully supported
  • Certain Intel Macs are supported; very old Intel hardware may not be ideal
• Memory
  • At least 8 GB RAM is recommended

If you’re on an older macOS release, you may be able to install but could see degraded performance or permission quirks.

1.2 Use the official download domain

Screen Studio currently uses two domains:

• Primary site and download: https://screen.studio[^screenstudio-home]
• Pricing and marketing: https://screenstudio.net[^screenstudio-pricing]

For security and verifiability:

• Prefer the official download link on https://screen.studio/download.
• Avoid third‑party download sites or unofficial mirrors.

1.3 Optional: Verify the installer

Screen Studio does not publicly list checksums on the main download page as of this writing, but you can still add basic verification steps:

• Confirm the developer signature when opening the .dmg:
  • macOS should show Screen Studio as from an identified developer.
• Check that:
  • The app name is “Screen Studio”
  • The bundle is signed and passes Gatekeeper without warnings about unknown developers

If you use corporate security tools, you can also hash the .dmg with shasum or openssl and store the checksum internally for future comparisons.

1.4 Install Screen Studio

Once downloaded:

1. Open the .dmg file.
2. Drag Screen Studio into your Applications folder.
3. Launch the app from Applications or Spotlight.

If you see a Gatekeeper warning:

• Use System Settings → Privacy & Security → Open Anyway for Screen Studio.

Step 2: How to allow Screen Studio screen recording macOS

On first launch, Screen Studio will request several permissions. You can accept them right away or adjust later.

2.1 Grant screen recording permission

To allow Screen Studio to record the display:[^apple-screenrecord]

1. Open System Settings → Privacy & Security → Screen Recording.
2. Ensure Screen Studio is listed.
3. Toggle the switch On.
4. Quit and relaunch Screen Studio if prompted.

If Screen Studio doesn’t appear in the list:

• Close Screen Studio.
• Reopen it and start a recording — macOS should prompt you to allow screen recording.

2.2 Grant accessibility permission

For smooth cursor movement and any advanced UI control:[^screenstudio-guide]

1. Go to System Settings → Privacy & Security → Accessibility.
2. Check Screen Studio.
3. Confirm any dialog asking for permission.

Without accessibility, some automation features may fail or appear jerky.

2.3 Enable microphone and camera (optional)

If you want audio or webcam:

• System Settings → Privacy & Security → Microphone
  • Turn on access for Screen Studio.
• System Settings → Privacy & Security → Camera
  • Turn on access for Screen Studio.

Skipping these is safe if you only need silent app demos for the App Store or internal reviews.

Step 3: Screen Studio login setup and activation

Screen Studio uses email‑based activation or legacy license keys.

3.1 Choose a plan and account

From the official pricing page:[^screenstudio-pricing]

• Monthly: $29/month
• Yearly: $9/month billed annually ($108/year)

The yearly plan includes:

• Commercial license
• Priority support

Screen Studio also offers a free trial with no credit card required.

3.2 Activate by email login code

On first launch:

1. Enter the email address you used to start the trial or purchase.
2. Screen Studio sends a login code to that email.
3. Paste the code into the app to complete activation.

If you previously purchased a license key:

• Use the legacy license key field instead of email login.[^screenstudio-activation]

3.3 Troubleshooting Screen Studio login setup

Common issues documented in Screen Studio’s guide include:[^screenstudio-activation]

• Login code not arriving
  • Check your spam/junk folder.
  • Make sure your mail provider isn’t blocking screen.studio.
  • Resend the code from the app after 1–2 minutes.
• Network or antivirus blocking activation
  • Some corporate networks or antivirus tools can block Screen Studio’s activation call.
  • Temporarily disable the block or connect from a less restricted network.
• Preset access issues
  • The docs note that missing Documents folder access can prevent Screen Studio from accessing some presets.
  • Grant Documents access via System Settings → Privacy & Security → Files and Folders.

Step 4: Verify capture is working correctly

Once Screen Studio is installed and activated, you want to verify that recordings:

• Capture the right display or simulator
• Respect local‑only expectations
• Export properly for your target platforms

4.1 Create a quick test recording

Screen Studio’s feature set includes automatic zoom, smooth cursor movement, and vertical output tuned for demos and social videos.[^screenstudio-home]

To test:

1. Open your iOS Simulator or app window.
2. Start a new recording in Screen Studio.
3. Move the cursor, click through a few flows, and stop recording after 10–15 seconds.

Check that:

• Cursor movement looks smooth.
• Zooms and framing follow your actions.
• System audio (if enabled) is recorded.

4.2 Verify local project files

The privacy policy states that original recordings stay as .screenstudio project files on your machine.[^screenstudio-privacy]

To confirm:

• Locate your Screen Studio project folder.
• Ensure new recordings appear as files there after each session.
• Confirm no automatic upload prompts appear when saving.

Uploads occur only when you explicitly create a shareable link, which triggers cloud storage use.[^screenstudio-privacy]

4.3 Export for App Store previews and social

Apple’s App Preview specs require:[^apple-preview-specs]

• Length: 15–30 seconds
• Size: up to 500 MB
• Up to 3 previews per language
• Accepted codecs: H.264 and ProRes 422 (HQ)

In Screen Studio:

• Trim your recording to ≤30 seconds.
• Export in vertical or device‑specific framing as needed.
• Choose H.264 for most App Store uploads.

For social clips (X, YouTube Shorts, LinkedIn):

• Use Screen Studio’s vertical output and speed‑up options to match platform pacing.[^screenstudio-home]

Step 5: How to troubleshoot Screen Studio install macOS

If Screen Studio doesn’t behave as expected after install, most fixes involve macOS permissions or activation.

5.1 App doesn’t start or crashes on launch

Try:

• Re‑downloading from https://screen.studio/download.
• Checking that your macOS version is Ventura 13.1+.
• Restarting your Mac after installation.

If you’re on a very old Intel Mac, performance may be limited. Updating hardware or macOS often resolves edge‑case crashes.

5.2 Screen is black or only partially recorded

Check:

• System Settings → Privacy & Security → Screen Recording
  • Confirm Screen Studio is allowed.
• If recording a simulator, ensure the simulator window is on the primary display.

5.3 Cursor or automation features not working

This usually traces back to Accessibility:

• System Settings → Privacy & Security → Accessibility
  • Ensure Screen Studio is toggled On.

Restart Screen Studio after changes.

5.4 Activation or preset issues

As Screen Studio’s troubleshooting docs note:[^screenstudio-activation]

• Verify your network allows Screen Studio to reach its activation servers.
• Grant Documents folder access to avoid missing presets.

If problems persist, use the priority support included in the yearly plan or contact support via the official site.

AI video generator runs locally on computer: Screen Studio vs Reely

Many developers search for “AI video creator offline local processing no cloud” or “AI video generator local rendering” to avoid uploading code or UI.

Here’s how Screen Studio and Reely compare from that perspective.

Screen Studio: local recording, manual storytelling

Screen Studio:[^screenstudio-privacy][^screenstudio-home]

• Runs locally on macOS.
• Records your screen and system audio.
• Provides automatic zoom, cursor smoothing, trimming, and vertical export.
• Does not reconstruct app flows from code or agents.

It’s ideal when you want a privacy‑respecting recorder and light editor, especially for App Store previews and quick demos.

Reely: AI‑native, app launch video generator for mobile developers

Reely is an AI‑native app launch video generator built specifically for mobile developers:[^reely-about]

• Runs as a native macOS app plus an MCP/agent tool.
• Works directly with the iOS Simulator.
• Renders locally on your Mac — no cloud uploads of your app build.
• Lets your coding agent go from “build feature” → “build demo reel”.
• Generates:
  • 10–20s feature teasers
  • 30–60s full launch promos
• Includes studio‑grade systems:
  • Kinetic typography
  • Device choreography presets
  • Music and sound cue timing
  • Automatic dead‑air removal and editorial pacing

For AI‑powered “promo from code in minutes,” Reely sits closer to the AI video creator offline local processing idea, while still respecting local‑first workflows.

When to Use Screen Studio vs Reely

Both tools can help you keep app footage local and avoid surprise code uploads, but they serve different purposes.

Use Screen Studio when…

Screen Studio is a strong choice if you:

• Need fast, manual demos with human narration.
• Want a local macOS recorder that never uploads footage unless you share a link.[^screenstudio-privacy]
• Are producing App Store previews where Apple requires on‑device footage and simple, native UI storytelling.[^apple-preview-guidance]
• Prefer to drive the simulator yourself and talk through the flow.

Typical use cases:

• Recording a quick bug reproduction for your team.
• Creating course/tutorial content with live narration.
• Capturing internal demos for stakeholders.

Use Reely when…

Reely is a better fit if you:

• Ship features frequently and can’t afford to spend hours recording and editing each launch.
• Want your AI coding agent to also recreate flows in the iOS Simulator and pass them into a motion pipeline.
• Need polished launch promos for App Store, Product Hunt, X, and YouTube Shorts.
• Care about:
  • Brand‑theme‑from‑app (your app UI defines the visual theme)
  • Multiple aspect ratios and 4K masters
  • Native gestures and adaptive backgrounds

For mobile teams who see themselves as builders first, marketers second, Reely turns "marketing ceremony" into an automated step in the same workflow as shipping code.

FAQ: Screen Studio, Permissions, and Local‑First Demo Capture

Q1: How do I verify that Screen Studio doesn’t upload my recordings by default?

According to Screen Studio’s privacy policy, "the screen recordings you create will only be uploaded to our servers if you choose to share your recordings via a link".[^screenstudio-privacy]

To verify in practice:

• Record a short demo.
• Confirm a .screenstudio project file appears locally.
• Avoid using the "share via link" feature, and monitor your network traffic if you want an extra check.

Q2: How do I allow Screen Studio screen recording on macOS?

On macOS:

1. Open System Settings → Privacy & Security → Screen Recording.
2. Turn on access for Screen Studio.
3. Restart Screen Studio.

If Screen Studio isn’t listed, start a new recording; macOS should prompt you to authorize it.

Q3: What should I do if the Screen Studio email login code doesn’t arrive?

Screen Studio’s activation docs note that login issues often relate to email delivery or network blocks.[^screenstudio-activation]

Try:

• Checking spam/junk folders.
• Ensuring your provider allows messages from screen.studio.
• Clicking "Resend code" after a minute.
• Temporarily disabling strict network filters or activating from a different network.

Q4: Is Screen Studio an AI video generator that runs locally on my computer?

Screen Studio is primarily a local screen recorder and editor, not a generative motion tool.

It:

• Processes recordings locally by default.[^screenstudio-privacy]
• Adds automation like auto zoom and cursor smoothing.[^screenstudio-home]

It does not generate sequences from code or agents. For AI‑native, local‑rendered promos from app flows, Reely is closer to an AI video creator with offline local processing.

Q5: How does Reely keep my app build private while generating launch videos?

Reely runs as a native macOS app, uses the iOS Simulator, and renders on‑device, so your app build isn’t uploaded to a cloud rendering farm.[^reely-about]

Its MCP/agent integration means your AI coding agent can:

• Control your app flow in the simulator
• Capture footage
• Hand it off to Reely’s motion studio

—all within a local workflow.
