Every new app, same story. You rebuild the buttons, bottom sheets, login screens and charts. Again.ExpoKit fixes that. It’s a bunch of ready-made UI components, charts and full screens for Expo and React Native. Run one command and the code lands right in your project. It’s yours, so tweak it however you want. No package to fight with, no black box.It works on iOS, Android and web. It even runs in Expo Go, because there are zero native modules. No prebuild, no dev client, no headache.What you get:<ul><li>70+ components: inputs, buttons, sheets, toasts, cards, nav, animations. All the stuff you keep rebuilding.</li><li>23 chart types, 347 variants: smooth, animated and touchable. They don’t look like they’re from 2015.</li><li>Full screens: Sign In, Checkout, Dashboard, Settings. Drop one in, change the colors, done.</li><li>Feels native: proper animations and gestures, not a web page squeezed into a phone.</li><li>Accessible out of the box, so you don’t have to go back and add it later.</li></ul>Spend your time on the stuff that makes your app different, not on the 50th version of a settings screen.
