Mockly: Screenshot Maker
50 Languages, One Workflow
Only for Mac
$12.99
Mac
Build's ready, screenshots aren't. Real 3D iPhone, iPad, Mac, and Apple Watch shots in 50 languages, uploaded straight to App Store Connect. Pay once. No subscription.
It's 11pm. The build is signed. The only thing between you and Submit for Review is a folder of screenshots.
Mockly takes you from raw captures to uploaded App Store screenshots in one sitting.
DROP IN, FRAME, DONE
Drop a raw screenshot onto a device and Mockly puts it inside a real 3D model: USDZ geometry rendered with SceneKit on Metal, not a flat PNG glued behind a cutout. Tilt it, rotate it, offset it, scale it. Dial the studio lighting up or down. Switch between a perspective and an orthographic camera.
Positioning is numeric, not a wrestling match with drag handles. Type the number, get the pixel.
UPLOAD, NOT JUST EXPORT
Most tools stop at a folder of PNGs. Mockly finishes the job.
It authenticates with your own App Store Connect API key, kept in the macOS Keychain. Pick your app, pick the version, pick your languages. Mockly renders every page, matches the screenshot display type to your artboard, uploads in chunks, and commits. No zip files. No browser tab. No renaming 40 PNGs at midnight.
Existing screenshots for the selected display type are replaced, and Mockly tells you first.
50 LANGUAGES, AND EACH ONE CAN DISAGREE
Add any of 50 App Store locales, right-to-left scripts included: Arabic, Hebrew, Urdu. Every locale inherits from your base language, so fixing the base fixes all of them. Unlink only what needs to change: devices, text styles, background, or images, each on its own. Ship different device art and a different background for Japan while the captions stay inherited.
Translate captions with AI using your own OpenAI, Anthropic, or Google key. It lives in your Keychain, and you pay your provider directly, at their rate.
Working with a human translator instead? Export every caption to CSV, hand it off, import it back. That path needs no AI and no key.
THE WHOLE APPLE LINEUP, NOT JUST PHONES
Real 3D models for iPhone 17 Pro Max, iPad Pro 11-inch, iPad Pro 12.9-inch, MacBook Pro 16-inch, Apple Watch Ultra, and Apple Watch Series 11.
Artboards sized the way App Store Connect wants them:
• iPhone 6.9-inch — 1320 x 2868
• iPhone 6.5-inch — 1242 x 2688
• iPad — 2048 x 2732
• Mac — 2880 x 1800
• Apple TV — 3840 x 2160
• Apple Watch — 410 x 502
• Landscape artboards for iPhone and iPad
If you ship a Watch app or a TV app, those sizes are already waiting for you.
THE PARTS PEOPLE MISS UNTIL THEY NEED THEM
• Device overflow: let one device bleed across two screenshots so the listing reads as one continuous shot
• Panoramic backgrounds: one artwork sliced across every page, 15 themes
• 140 gradient presets, solid colors, or your own image
• 27 type families, with shadow, stroke, and per-locale styling
• Linked folders: name a file en_page1_1.png and Mockly maps it to the right locale, page, and device on its own. Re-capture, rescan, done
• Multi-page projects with reordering, duplication, and per-page naming
WHAT YOU SEE IS WHAT UPLOADS
Preview and export share one CoreGraphics renderer and one set of layout math. Exports land at exact pixel dimensions with no alpha channel, which is what App Store Connect accepts. PNG or HEIC.
YOUR MAC, YOUR KEYS
Mockly runs entirely on your Mac. Your projects, screenshots, and API keys stay on your machine. The only places anything is sent are Apple, when you upload, and your chosen AI provider, when you use AI. Nothing routes through me.
PAY ONCE
One-time purchase. No subscription, no per-seat math, no watermark. You buy it, you own it, it keeps working.
BUILT FOR
• Indie developers shipping in more than one language
• Small teams who rebuild the same screenshots every release
• Anyone who has exported at the wrong size at 1am
Mockly is built by one independent developer. If something doesn't work the way you expect, or there's a device or artboard size you need, the support link on this page reaches me. Most of what's in this list started as somebody's email.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New models. And now you choose which one.
Mockly's AI translation has moved to the current generation from Anthropic, OpenAI and Google. Every provider is up to date, Gemini included — no more sending your store copy to last year's model.
The new part is the choice. Take the strongest model when a headline has to land in twenty languages. Take the quick one when you're filling fifty locales the night before submission.
Still your key, still your account, still no subscription and no credit packs. You just have more say in what you're paying for.
