Study screens, flows and paywalls from top-earning iOS apps, then build from what wins.
A builder, not just a researcher
Agent skills that make AI agents genuinely good at building mobile apps — studied against the top-grossing apps, finished to a simulator-verified bar.
Appllama is the design library of top-grossing mobile apps — their real screens, flows, and UI patterns, with revenue and download context. These skills turn that library into an agent's working method: study every screen of the apps that already win, extract the category's design language, then build screens that hold up next to them.
The skills
appllama-usage — The research engine: how to use the Appllama MCP like a design director — the full tool map, and the playbooks for building an app from scratch, improving an existing screen, and flow & element research.
appllama-app-design-skill — The build bar: native-feeling Expo / React Native screens — Apple HIG fidelity, semantic colors, native controls, anti-slop discipline, navigation that behaves (push vs replace, sheets and overlays, the one-way doors where back must not exist), a strict motion bar (should it animate at all, springs that carry the finger's velocity, nothing on the JS thread), generated image assets, and a full-motion simulator loop (whole flows recorded and scrubbed frame by frame, not screenshots).
These are designed as a pair: usage decides what to study, design decides how to build, and both insist the loop only ends in a simulator with a screen you can't fault.
Install
One command from your project root — works with Claude Code, Cursor, Codex, and 70+ other agents:
npx skills@latest add appllama/appllama-skills
Installation variations
For specific agents without prompts:
npx skills@latest add appllama/appllama-skills -a claude-code -a cursor -y
To install user-wide instead of per-project:
npx skills@latest add appllama/appllama-skills -g
Install individual skills
appllama-app-design-skill stands on its own — the native-quality build bar, anti-slop discipline, and the full-motion simulator loop work with or without the Appllama MCP connected:
npx skills@latest add appllama/appllama-skills --skill appllama-app-design-skill
Use the same --skill flag to install only appllama-usage if you want just the research engine.
Manual install
Skills are plain directories — copy them into your agent's skills folder (.claude/skills/ per project, ~/.claude/skills/ user-wide, or your harness's equivalent):
git clone https://github.com/appllama/appllama-skills cp -r appllama-skills/skills/* ~/.claude/skills/
Connect the Appllama MCP
appllama-usage runs on the Appllama MCP; appllama-app-design-skill is sharper with it connected. The endpoint:
Add it as a custom connector in Claude, Cursor, Codex, or any MCP client and approve the connection with your Appllama account. MCP access is part of Pro; credits reset in full on the 1st of each month. Every call spends one credit — get_credits is always free.
Try it
With the MCP connected and the skills installed, ask your agent:
- Build me a habit tracker. Study the top-grossing habit apps first and don't stop until every screen survives the simulator comparison.
- Make this screen better. (paste a screenshot, code, or a "Copy Screen ID" ref from appllama.io)
- How do the best fitness apps structure onboarding — how long, what does each step earn, and where does the paywall sit?
- Wire up the checkout flow. Decide which screens push, which present as sheets, and make sure nobody can go back into the paywall after paying.
- Review the animations in this app — what should be deleted, what's on the wrong thread, what's missing velocity — and give me the plan.
