A Picker component for React Native which emulates the native select interfaces for iOS and Android. For iOS, by default we are wrapping an unstyled TextInput component. You can then pass down styles to customize it to your needs. For Android, by default we are using the native Picker component. If you prefer, you can set useNativeAndroidPickerStyle to false, which will also render an unstyled TextInput component. You can then pass down styles to customize it to your needs. For either platform, you can alternatively pass down a child element of your choice that will be wrapped in a touchable area. The component defaults to using the native Android Picker in its un-selected state. Setting this flag to false will mimic the default iOS presentation where a tappable TextInput is displayed.

Realm’s mobile database is an open-source, developer-friendly alternative to CoreData and SQLite. Start in minutes, port your app in hours, and save yourself weeks of work. Realm’s object-oriented data model is simple to learn, doesn’t need an ORM, and lets you write less code. Realm’s local database persists data on-disk, so apps work as well offline as they do online. Realm is fully-featured, lightweight, and efficiently uses memory, disk space, and battery life. Realm was built for mobile developers, with simplicity in mind. The idiomatic, object-oriented data model can save you thousands of lines of code. Realm’s live objects mean data updated anywhere is automatically updated everywhere. If you need to freeze elements of your data for Reactive frameworks, you can do that, too.

Sentinel is a filesystem-backed document DBMS built in Rust that prioritizes compliance, transparency, and auditability over raw performance. Unlike traditional databases, every document is a plain JSON file, making your data immediately forensic-friendly and Git-versionable. Perfect for regulated industries requiring GDPR, SOC 2, HIPAA, or PCI-DSS compliance. Sentinel provides async operations with automatic BLAKE3 hashing and optional Ed25519 signatures for cryptographic integrity. Data encryption supports AES-256-GCM, XChaCha20-Poly1305, and Ascon-128. Each document includes full audit metadata—creation timestamps, version history, hashes, and signatures—viewable with standard UNIX tools. Designed for edge deployments, compliance systems, audit logs, certificate management, and regulatory reporting. No server required, works entirely on filesystem with Git-based replication. Zero vendor lock-in—migrate anytime using standard tools like rsync, tar, or git.
