    I built TinyDebt — a minimal debt-tracking app (no backend, instant syncing)

    A developer shares the technical decisions behind building TinyDebt, a minimal debt-tracking mobile app. The app uses React Native with Expo, stores data locally using AsyncStorage with optional Supabase backups, and requires no user accounts or backend. The local-first architecture enables instant actions, offline functionality, and fast performance. The UI prioritizes simplicity with neutral colors and minimal screens, while the data model uses serializable TypeScript types for easy storage and migrations.

    Why Building Mobile Apps Is So Much Harder Than It Looks

    Mobile development is a demanding field requiring careful management of limited hardware resources, unpredictable network conditions, strict app store review processes, and high privacy expectations. Developers must optimize for smooth performance, handle offline capabilities, and ensure robust security, all while meeting high user expectations and dealing with difficult testing and debugging processes.

    Apple and Google won’t like this...

    The Free Software Foundation announced the Libriophone project, led by Rob Savois, aiming to create a fully open-source smartphone by replacing all proprietary firmware, drivers, and binary blobs with free software alternatives. Unlike existing solutions like LineageOS that still contain proprietary code, this initiative seeks complete software freedom through reverse engineering. The project faces significant challenges including the massive technical undertaking of replacing closed-source components, limited historical adoption of similar efforts like Replicant, and the dominant Apple-Google duopoly that controls mobile ecosystems.

    Proto vs JSON: When to Use Which (and Why)

    Data serialization plays a crucial role in app development, with JSON and Protocol Buffers (Proto) being two commonly used methods. JSON is human-readable and easy to use for public APIs, prototypes, and configurations, while Proto offers faster and smaller data handling, ideal for high-performance applications, microservices, and IoT devices. Choosing between them depends on the specific use case, whether readability or performance is prioritized.

    I switched to eSIM in 2025, and I am full of regret

    eSIM technology is replacing physical SIM cards in modern smartphones, with Google's Pixel 10 series becoming the latest to drop the physical SIM slot. While eSIMs save space and allow multiple profiles, the transition has proven frustrating for users accustomed to easily swapping physical SIM cards. Apple pioneered the eSIM-only approach with the iPhone 14, though the space savings have been modest—around 8 percent more battery capacity. The shift represents a significant change in how mobile subscribers manage their phone service, moving from removable cards to programmable, soldered components.
