STEP 01 / CONNECT
Start with a cable.
Connect your unlocked iPhone over USB. Approve “Trust This Computer” on your phone, then select it in Mask Desktop.
Apple's free development signing usually needs renewal within 7 days. Access-code expiry is separate. Developer Mode and developer trust still require your approval on the iPhone.
03 / CHOOSE YOUR COMPUTER
Make yourself
at home.
Same Mask. Two companions. Choose your platform for the download and its own installation guide.
For Mac.
⌘Apple silicon · macOS 11 or later

Unnotarized preview. Opening instructions are on the next page.
For Windows.
⊞Windows 10 / 11 · Intel / AMD x64
Desktop 0.1.5 · 49.8 MiB setup EXE
Unsigned preview. Build and basic launch checks passed; real iPhone installation remains unverified.
Use only with devices you own or have permission to test. Your administrator-issued access code is still required. No Apple Account sign-in happens on this website.
CLEAR BY DESIGN
Local installation.
Honest about the connections.
The app installs over USB on your computer. Signing and renewal contact Apple and a signing helper; access verification contacts Mask's online service with an installation token and, at activation, your access code.
Your pairing record is device-specific and is not included in public downloads. This website has no Apple sign-in form or added analytics scripts. Hosting providers may process standard connection logs.

Before
you begin.
What am I downloading?
Mask Desktop, the Mac or Windows companion that bundles the Mask iPhone app for installation. You do not need Xcode to use the desktop installer.
Does everything work offline?
No. Apple signing, the signing helper and Mask access verification need internet. Maps, search and route planning may also use network services.
Why do I need an Apple Account?
Apple's development signing uses your account to provision the iPhone app. Enter details directly in the desktop app, not this site or a chat. Account requirements and certificate or App ID limits can prevent installation.
Do I have to renew it?
Yes. Free Apple development signing typically lasts 7 days. Return to the desktop app to refresh it before expiry. Successful unattended self-renewal is not guaranteed.
What do I need on my phone?
Follow the desktop's guide for Developer Mode, developer trust, your phone's pairing record and LocalDevVPN. iOS and network conditions affect availability.
What does “development preview” mean?
The Mac app is not Developer ID–signed or notarized; the Windows installer is not Authenticode-signed. Read your platform's notices. Windows build and launch checks do not yet verify real-device installation or refresh.
