The workflow covers using Claude to plan features, generate UI designs via Claude's design tool, set up a React Native (Expo) mobile app and Next.js web dashboard sharing a Supabase database, integrate Claude's vision API for receipt parsing, use multi-agent workflows with different model tiers (Opus 4.8 for complex tasks, Sonnet 5 for simpler ones), add Lottie animations, and preview the app live on a phone via Expo Go. The post also discusses why niche B2B utility apps in boring categories like receipt tracking can generate $40K–$80K/month in App Store revenue. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What tech stack does Claude Code recommend for building a receipt scanning app with a shared mobile and web database? Claude Code recommends Expo React Native for the iOS app, Next.js for the web dashboard, and Supabase for the shared database, so both the mobile app and web dashboard read and write the same data. Claude's vision API is used to scan and parse receipt photos into structured, categorized data automatically. _Developers comparing AI-assisted app stacks can follow ongoing Claude Code and Supabase coverage on daily.dev._ ### How can I use multiple AI models like Opus and Sonnet together to reduce token costs in Claude Code? Use a multi-agent workflow where a stronger model like Opus handles architecture design, code review, and final quality checks, while a cheaper model like Sonnet handles routine implementation tasks such as building individual pages. This division lets you request a detailed plan explaining which agent does which task and why, keeping token spend efficient without sacrificing quality on critical decisions. _Anyone tuning multi-agent coding workflows can track model and pricing changes via daily.dev._ --- Tags: [#react-native](https://daily.dev/tags/react-native), [#claude-code](https://daily.dev/tags/claude-code), [#vibe-coding](https://daily.dev/tags/vibe-coding), [#supabase](https://daily.dev/tags/supabase) [View this post on daily.dev](https://daily.dev/posts/how-i-built-an-80k-mo-mobile-app-with-claude-code-full-vibe-code-tutorial--9p07j1kys) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How I built an $80K/Mo mobile app with Claude Code (Full Vibe Code Tutorial)","url":"https://daily.dev/posts/how-i-built-an-80k-mo-mobile-app-with-claude-code-full-vibe-code-tutorial--9p07j1kys","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-i-built-an-80k-mo-mobile-app-with-claude-code-full-vibe-code-tutorial--9p07j1kys"},"datePublished":"2026-07-17T10:25:08.245Z","dateModified":"2026-09-14T09:28:06.064Z","description":"A walkthrough of building a receipt-scanning mobile app (iOS) using Claude Code without writing code manually.
