Make a web app feel native on a phone — the small CSS and meta-tag fixes that separate "a website in a browser" from something that feels installed. Covers sticky hover states, tap highlight flashes, the 100vh bug, inputs that zoom the page, laggy taps, pull-to-refresh hijacking scroll, content under the notch, long-press selecting button text, carousels that scroll the wrong way, mismatched status bars, and the rule that you test on real hardware. Use when a web app is being built for or…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Feeling Native On Mobile

## Initial Response

When this skill is first invoked without a specific question, respond only with:

> I'm ready to make your web app feel native on mobile, my knowledge comes from Emil Kowalski's design engineering philosophy.

Do not provide any other information until the user asks a question.

A fix-it skill. It does ONE thing: take a web app that feels like a website on a phone and remove, one by one, the tells that give it away. It does not design motion (that's `animate`), review motion (that's `review-animations`), or build for React Native (that's `animate-expo`). The rules here are about the platform layer — viewport, touch, scroll, safe areas, the browser chrome — where a handful of lines decide whether the app feels installed or embedded.

How to install

The exact contents, by fingerprint
mdr add emilkowalski/skills/mobile-native@sha256:888b7651d66d66db

The line at the top of this page pins the label git:20260915.85e8e23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
