What Is Jev? The AI Model That Makes Decisions Instead of Writing

· 11 min read
Full Stack Developer

Most AI products ask a language model to generate an answer, even when the application only needs a decision. A support router does not need a paragraph. It needs billing, technical, or sales, plus enough uncertainty information to decide whether a person should review the result.

Jev is a new model from TypeSafe AI built around that distinction. It accepts context and focused questions, then returns typed choices, scores, and probabilities rather than free-form text. TypeSafe calls it its first System One Model: a model designed to make bounded decisions inside software.

Expo SDK Upgrade Guide: Upgrade Now, Test First, or Wait?

· 8 min read
Full Stack Developer

An Expo SDK upgrade is not just a package update. It can change the React Native version, native build tools, configuration plugins, Expo Go support, and the behavior of the iOS and Android projects generated by prebuild.

The safest decision is not always "upgrade immediately." It is the option that keeps your app buildable, testable, and recoverable. This guide gives you a repeatable way to choose between upgrading now, testing in a separate branch, or waiting for a specific blocker to be resolved.

Supabase Production Checklist for React Native and Expo Apps

· 9 min read
Full Stack Developer

A React Native app can connect to Supabase in minutes. Production readiness takes more work: every exposed table needs an authorization model, mobile auth links must return to the right build, database changes need a repeatable release process, and the team needs a way to detect and recover from failures.

This checklist starts after the basic integration works. Use it before the first public release and repeat the relevant sections before major launches.

How to Turn a WooCommerce Store into a Mobile App

· 9 min read
Full Stack Developer

Turning a WooCommerce store into a mobile app starts with an architecture decision, not a code generator. A WebView wrapper, a hosted app builder, and a source-owned React Native app can all put a store on a phone, but they offer very different levels of user experience, control, security, and long-term cost.

This guide helps you choose the right path and understand the work that remains after the first product screen appears.

Flutter 3.47: What to Check Before You Upgrade

· 5 min read
Full Stack Developer

Flutter 3.47 is the current stable release, and this update changes more than a version number. Material and Cupertino are available as standalone packages, Widget Previews are stable, Impeller is the default desktop renderer, and the platform baselines are moving forward.

Use this short checklist before running flutter upgrade on an older project. The goal is to find migration work while it is still a controlled change—not after it becomes a release blocker.

React Native 0.87: A 10-Minute Upgrade Readiness Check

· 6 min read
Full Stack Developer

React Native 0.87 is now the active stable release. It makes the Strict TypeScript API the default, updates the Android build baseline, raises the minimum Node.js version, and introduces changes that can expose assumptions in older projects.

This is a practical pre-upgrade check. You can run it in about ten minutes and decide whether your project is ready, needs a small preparation pass, or should stay on its current version until a dependency catches up.

5 AI Changes App Builders Should Know

AI app development changed quickly again this summer. Frontier models became less expensive, coding agents became more capable, and the mobile platforms moved serious AI workloads closer to the device.

If you have been away from mobile development for a few months, this is the short version of what changed, what is real today, and what is worth testing in your next app.

App Intents for SwiftUI Apps: Siri, Shortcuts, Spotlight, and Action Button

Expose real product actions to the system instead of treating your app as an isolated screen stack.

SwiftUI App Intents architecture connecting app actions to Siri Shortcuts Spotlight and widgets

App Intents are becoming one of the most important integration points for iOS apps. They let your app expose actions and data to system features such as Siri, Shortcuts, Spotlight, widgets, and other surfaces that can help users act without opening the full app first.

For SwiftUI templates, this is a major opportunity. A template usually already has a predictable product loop: browse products, start a chat, save a listing, log a workout, check an order, or create a reminder. App Intents turn those loops into system-level capabilities.

This guide explains how to plan App Intents in a SwiftUI app template:

  • identify user actions worth exposing;
  • model app entities and queries;
  • decide which actions belong in Shortcuts or Siri;
  • connect intents to widgets and Spotlight;
  • test the integration before release.

Expo Router API Routes and EAS Hosting: A Backend for React Native Apps

Expo Router API routes give React Native teams a practical middle ground between "everything is client-side" and "we need a separate backend project before we can ship." With EAS Hosting, those routes can be deployed alongside an Expo Router web app and used for server-side work such as secrets, validation, webhooks, AI calls, and small backend endpoints.

Firebase AI Logic vs Genkit for Flutter: Which Architecture Should You Use?

· 6 min read
Full Stack Developer

Flutter teams now have two strong Google-backed paths for AI features:

  • Firebase AI Logic for direct AI calls from mobile and web apps;
  • Genkit for full-stack AI flows, tools, structured output, and agentic workflows.

The right choice is less about which one is "better" and more about where the AI decision should live: in the Flutter client, in a backend flow, or across both.

Firebase AI Logic vs OpenAI Backend for React Native AI Apps

· 6 min read

React Native teams now have two practical ways to add serious AI features to a mobile app:

  • call Gemini models through Firebase AI Logic from a Firebase-aware app;
  • keep AI orchestration on your own backend and call OpenAI from the server.

Both approaches can be correct. The wrong choice is usually the one that ignores secrets, user identity, App Store release cycles, cost controls, and how quickly your AI product will evolve.

Flutter App Store Privacy Checklist: Apple Privacy Manifests and Google Play Data Safety

Flutter apps are cross-platform, but privacy review is still native. Your pubspec.yaml dependencies can pull in iOS pods, Android libraries, analytics SDKs, crash reporters, payment SDKs, Firebase packages, and permission handlers that affect App Store and Google Play disclosures.
