Hi!I&#x27;ve been frustrated with the fact that the beautiful NumberFlow library for web (link) is not available on React Native - a platform that I think is much more animation native than the web is. And there are no alternatives of the same quality available. So I reimplemented it myself, basically from the ground up.Introducing Number Flow React Native.I am aiming for this to be the best number animation library for React Native.- Beautiful animation easing directly inspired by web NumberFlow
- Supporting both Native and Skia versions
- Full i18n support for locales, things like compact or scientific notations, etc.
- TimeFlow component for timers and counters
- Custom digit bounding for things like binary
- Supporting 37 different numeral systems such as Arabic, Thai, and many others
- A dedicated, shared worklet mode for as much FPS as possible perfect for sliders or gestures for example
- Built on top of React Native Reanimated v3+
- Also supports web via Expo WebPlease check out the docs: <a href="https:&#x2F;&#x2F;number-flow-react-native.awingender.com&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;number-flow-react-native.awingender.com&#x2F;docs</a>

Show HN: I created a beautiful number animation library for React Native

I spent 10 years building React Native apps. SwiftUI made me quit in 2 weeks

Every AI app builder on the market right now generates cross-platform code. Bolt, Lovable, Rork, they all output React Native or Expo under the hood, or worse, web apps wrapped in a native shell. And I get why. React has more documentation, more training data for LLMs, and it&#x27;s easier to build a platform around, one codebase, two platforms, faster time to market.But the apps are bad.I tried building a polished app with one of these tools and the moment I needed a premium, native-feeling design, I hit a wall. Everything looked like AI slop. Animations were janky. Platform conventions were ignored. Try getting one of these approved on the App Store without weeks of cleanup. Apple doesn&#x27;t love Expo wrappers, and users can feel the difference whether they can articulate it or not.So when I started building Nativeline, I made what most people told me was the wrong bet: generate real SwiftUI for iPhone, iPad, and Mac. No React Native. No web views. Actual native Swift that opens in Xcode and builds.This was significantly harder. Here&#x27;s why.The biggest challenge is that LLMs are trained on the entire history of Swift, including five years of deprecated APIs, old UIKit patterns, and SwiftUI code from when it was half-baked. Getting the model to generate modern, clean SwiftUI without reaching for GeometryReader for every layout problem or calling APIs that haven&#x27;t existed since iOS 15 was a serious effort. It&#x27;s not just about generating code that runs. It&#x27;s about generating code that builds without errors, follows current conventions, and reads like something a good Swift developer would actually write.Then there&#x27;s keeping up with Apple. When Liquid Glass dropped, every existing LLM was useless for generating UI that used the new framework. If you&#x27;re generating React Native, you don&#x27;t really care, you&#x27;re abstracted away from platform changes. But if you&#x27;re generating native Swift, staying current with Apple&#x27;s frameworks isn&#x27;t optional. It&#x27;s the whole point.What we got right: The output is real SwiftUI that you own. Full Xcode project on your machine. One user described a Mac app idea, iterated on it over about 6 days, and is now selling it on the Mac App Store. He didn&#x27;t write Swift before that. The code was clean enough to ship and maintain.What we&#x27;re still working on: Complex backend integrations are hard. Database connections, Supabase, CloudKit, anything with real data persistence, still produce more errors than we&#x27;d like. We&#x27;re working on building deeper internal documentation for the AI specifically around database patterns, potentially our own managed backend, so the model has reliable patterns to follow instead of hallucinating schema configurations.I think the industry defaulted to React Native because it was the easier path for the builder of the tool, not because it was better for the user of the apps. The hard bet is generating native code. But the output difference is obvious the moment you use the app.Nativeline is free to try: https:&#x2F;&#x2F;nativeline.aiHappy to answer questions about the technical approach, the tradeoffs, or anything else.

Every AI app builder outputs React Native. I chose real Swift instead

Hello HN,I built Mindwtr because I wanted the speed and polish of apps like Things 3, but with the data ownership of Emacs Org-mode.It is an open-source (MIT&#x2F;AGPL), local-first implementation of the Getting Things Done (GTD) methodology.The Stack:
- Desktop: Tauri v2 (Rust) + React. It runs heavily on Arch Linux (my daily driver).
- Mobile: React Native (Expo) on Android.
- Sync: It treats the file system as the source of truth. Data is stored in JSON&#x2F;TOML, allowing you to sync via Syncthing, Dropbox, or Git.Key Features:
- &quot;Copilot&quot; Capture: Uses local regex and logic to auto-tag contexts&#x2F;projects as you type.
- Privacy: No cloud servers. Your data never leaves your device unless you sync it yourself.
- AI Hooks: Optional integration (BYO Key) to break down vague tasks or review stale lists, but completely functional offline without it.I am a PhD student and this has been my side project to manage my own research chaos. I&#x27;d love feedback on the architecture or the workflow.Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;dongdongbh&#x2F;Mindwtr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dongdongbh&#x2F;Mindwtr</a>

Flutter and React Native App Development in Coimbatore – Cross-Platform Pros

I built and open-sourced a collection of 20 production-ready React Native templatesEach template is a single, self-contained screen. All built with React Native New Architecture, TypeScript, and 4 core libraries: Reanimated, Gesture Handler, Unistyles, and React Native SVG. No UI framework, no heavy dependencies. Framework-agnostic, works with Expo Router, React Navigation, or custom navigation.I started this project before AI got good at writing UI code. The plan was different then. But building UI screens is becoming a commodity, AI makes it cheaper every day, and the trend is clear.Developers can move much faster now — no need to rebuild the same onboarding flow every time. So these are more useful as open reference implementations, showing what&#x27;s achievable with a focused, minimal stack, than as a gated product.Templates also include some basic documentation to help AI coding assistants understand the structure if you want to use them for customization.Demo app available on TestFlight and Google Play if you want to see the animations and interactions before looking at code (see documentation).

React Native Windows v0.81

# This is a Expo Framework

Expo is a framework and a platform for universal React Applications. 
It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy,
and quickly iterate on iOS, Android, and web Apps from the same JavaScript/TypeScript codebase.

# Requirements

- Node.js LTS release or greater
- Git
- Watchman for macOS users

# Recommended Tools

- VSCode Editor
- Yarn
- Windows users: PowerShell or Bash via WS

# Installing Expo CLI

```bash
 # install the command line tools
 npm install --global expo-cli
```

## Getting Started 

Create a new app:
At this point we should have Expo CLI installed on our development machine and the Expo Go App on an iOS or Android physical device or emulator.
If not, go back to the Installation guide before proceeding.

# Initializing the project

```bash
# Create a project named my-app.
# Select the "blank" templata when promped
expo init my-app

# Navigate to the project directory
cd my-app
```

First, run the development server:

```bash
expo start
# or
npm start
```
