Straight answers before you build.
What people ask about building a native iOS and Android app, answered in two sentences each, then the details and the limits.
Questions, answered
How do I build a native iOS and Android app without writing the UI by hand?
Design the screens and the navigation in a visual builder that outputs real native code, then build that code once for each platform. With opointo you drag blocks onto screens in the browser and draw arrows between them, and your coding agent turns the design into one Expo project with native controls on iOS and Android.
What is the best way to get Liquid Glass in a React Native or Expo app?
Use the real iOS system controls wherever iOS has one, since an app built against the iOS 26 SDK gets Liquid Glass on them for free, and save expo-glass-effect for your own surfaces, with a blur fallback on older iOS. Move glass with transforms and keep it mounted: fading it, or mounting it on demand over other glass, renders it blank.
Can my coding agent build a whole app from a visual design?
Yes, if the design reaches the agent as structured data rather than a picture, which is how opointo works: you design the screens and draw the navigation in the App Builder, and your agent writes a complete Expo project from it. From a screenshot alone, an agent gets one screen close but has to guess the navigation, the native controls and the app shell, which is where apps break.
Expo app builder: what should I look for?
Look for a builder that exports a normal Expo project you own, uses each platform’s real controls, and wires the navigation and app shell as well as the screens. Then check what happens to your app when you stop paying, which toolchain it needs, and whether it says plainly which iOS and Android versions it has verified.
Comparisons
Should I use opointo, or just ask my coding agent to build the app?
Your coding agent can write a React Native app on its own, but it has to guess the navigation, the native controls and the app shell, and you review every guess. opointo gives the agent your design as data and an app shell already tested on both platforms, so it writes less, checks what it wrote, and does not need the most expensive model.
No-code builder, AI app builder, a developer, or opointo: how should I build my mobile app?
If you never want to see code, use a no-code builder; if you want a first version from a prompt today, use an AI chat builder; if the app is unusual and you have the budget, hire a developer. opointo sits between them: you design visually and your own coding agent produces a native Expo app you own, which suits developers and technical founders.
