Mobile Development with Fexingo: iOS, Android, and App Building Conversations

Fexingo

Lucas and Luna explore the craft of building mobile apps, from iOS and Android fundamentals to architecture decisions and deployment workflows. Each episode digs into a single practical question: how to structure a feature, manage state across platforms, or optimize for performance without sacrificing readability. The hosts debate real-world trade-offs using concrete examples—a navigation pattern in SwiftUI versus Jetpack Compose, the role of dependency injection in testable code, or when to reach for a cross-platform framework. They avoid hype and focus on what works in production, citing open-source libraries and documented case studies from companies like Airbnb, Spotify, and Basecamp. Lucas brings a journalist's rigor, asking why a team chose one approach over another; Luna pushes back with hands-on nuance, drawing from her own experience shipping apps. Together, they serve engineers, technical leads, and product managers who want to stay sharp without chasing every new tool. The conversation assumes you already know the basics and are looking for deeper reasoning—not tutorials. By the end of each episode, you'll have a clearer sense of how to evaluate trade-offs in your own codebase. What does it really take to build an app that users love and teams can maintain? #MobileDevelopment #IOS #Android #AppBuilding #SwiftUI #JetpackCompose #CrossPlatform #SoftwareArchitecture #MobileEngineering #StateManagement #DependencyInjection #AppPerformance #CodeQuality #TechPodcast #Technology #Business #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

    How Apps Use On-Device AI to Count Reps and Correct Form

    Gym apps promise to count your reps and fix your squat form, but how do they actually work without a cloud server? In this episode, Lucas and Luna explore the world of on-device AI for fitness tracking. We start with a concrete example: the popular app RepCount, which uses your phone's camera to track your barbell movements in real time, all locally on your device. Lucas explains the technical magic behind it — from 2D pose estimation with models like MoveNet, to converting joint coordinates into rep counts using clever algorithms that detect the bottom of a squat or the lockout of a bench press. Luna brings up the tricky question: can an on-screen skeleton really tell if your form is safe? We break down the limitations, like camera angles and occlusions, and how apps are starting to use depth sensors on newer phones to improve accuracy. We also discuss the privacy angle: why keeping all this data on-device is a big deal for gym-goers who don't want their workout videos uploaded to a server. Plus, we touch on the latest trend of integrating these AI coaches into smart watches and AR glasses. If you've ever wondered whether your phone can truly be your personal trainer, this episode is for you. #OnDeviceAI #FitnessApps #RepCounting #FormCorrection #PoseEstimation #MobileAI #WorkoutTech #PrivacyFirst #GymTech #AIcoach #TechTrends #MobileDevelopment #iOS #Android #FitnessTracking #FexingoBusiness #BusinessPodcast #Technology Keep every episode free: buymeacoffee.com/fexingo
