Hi,
My name is Andrew. For the last few months, we’ve been working on Screenshot Bro, a native Mac app for designing, localizing, and uploading App Store screenshots.
Problem:
App Store screenshots look simple until you actually have to ship them. The moment you support multiple device sizes and locales, the workflow becomes repetitive fast:
- Updating the same layout across iPhone + iPad sizes
- Keeping 10+ locales visually consistent
- Re-exporting everything after every tiny text change
- Losing track of screenshot variants and App Store requirements
- Manually uploading assets into App Store Connect
Most tools still treat screenshots as separate static images instead of one connected project, so the process turns into a lot of repetitive busywork very quickly.
Solution:
Screenshot Bro is a native Mac app, and we tried to make it different compared to other solutions available on the market in two ways:
1) A continuous canvas for all device sizes and locales. The whole project lives on one large canvas, more like Figma. You can zoom out to see every device size, locale, and screenshot row at once, then zoom back in to edit details. So you see every device size and each locale on one canvas, keep layouts consistent, adjust only once, without losing track of variants, and get the final screenshots ready for App Store Connect without manually babysitting every export.
2) Local-first AI-editable project files that kill screenshots grind. Projects are stored locally as plain JSON, with a public JSON schema on GitHub. The idea is that you own the files, similar to how Obsidian works with Markdown. It also means you can point an AI agent at the schema and project file and ask it to do things like: make the text larger, translate all labels to Spanish, and change the backgrounds to bright gradient colors. Since the format is structured and documented, the agent can make those edits directly instead of trying to manipulate a closed/proprietary file. In practice, it completely kills the app store screenshots grind.
Features:
It also has many other cool features:
- Real device frames, including iPhone, iPad, MacBook, iMac, Android-style, and invisible layout frames.
- Template gallery with ready-made visual styles to start from quickly.
- Multi-row canvas for building complete screenshot sets at once.
- Shape tools: text, images, SVGs, rectangles, circles, stars, devices, rotation, clipping, borders, and opacity.
- Rich backgrounds: colors, linear/radial/angular gradients, images, and tiled image fills.
- Locale workflow with 30 language presets and per-locale text overrides.
- Batch import, simulator capture, and export to PNG/JPEG.
- App Store Connect upload support with credential storage and validation.
- iCloud sync with conflict merging and deleted-project tombstones.
- Pro-oriented editing niceties: snapping guides, keyboard shortcuts, custom fonts, Quick Look previews, and undo/redo.
We’re trying to figure out whether the “continuous canvas” and the “local-first + AI-editable project files” angle actually makes sense for this kind of app, or whether we’re overcomplicating something that should just be a straightforward screenshot generator.
Would love honest feedback from people who ship apps. Is this useful, or is it solving a problem you don’t really have?
Screenshot Bro is available on the App Store if anyone wants to try it.
