Compare runtimes and release constraints through independent exercises.

Choose a platform using device capabilities and delivery needs.

## Application platforms

- [Choose an application platform from device requirements](https://yishto.com/en/learn/application-platforms/choose-runtime-and-platform/index.md): Use an offline document reader to turn file access, notifications, background work, and distribution into testable requirements before choosing a runtime and application platform.
- [Structure an offline reader with SwiftUI](https://yishto.com/en/learn/application-platforms/swiftui-offline-reader/index.md): Design a SwiftUI reading list with stable document identity, explicit navigation, persistent offline storage, and cancellable downloads, separating view state from durable library data.
- [Build a recoverable mobile form with Compose](https://yishto.com/en/learn/application-platforms/compose-offline-checklist/index.md): Build explicit draft, validation, persistence, and conflict states for a device inspection form, connecting Compose recomposition with Android lifecycle and offline recovery.
- [Manage pages and asynchronous state in Flutter](https://yishto.com/en/learn/application-platforms/flutter-reading-library/index.md): Build a teaching library around Flutter widget identity, navigation, and asynchronous request ordering, with a persistent repository and explicit stale-response, failure, and disposal handling.
- [Design offline notes with React Native and Expo](https://yishto.com/en/learn/application-platforms/expo-offline-notebook/index.md): Design React Native and Expo reading notes with durable local records, a synchronization queue, idempotent requests, explicit conflicts, and platform-specific permissions.
- [Isolate file and interface privileges in an Electron tool](https://yishto.com/en/learn/application-platforms/electron-transcript-workbench/index.md): Separate Electron main, preload, and renderer responsibilities in an interview workbench, using approved file IDs, narrow IPC messages, and explicit transcription job states.
- [Add controlled offline behavior to learning pages](https://yishto.com/en/learn/application-platforms/pwa-offline-learning/index.md): Give public learning documents, static assets, and private requests separate policies, explaining service-worker lifecycle, versioned caches, offline fallbacks, and consistent updates.
- [Handle connection and interface state in a Qt device client](https://yishto.com/en/learn/application-platforms/qt-device-console/index.md): Use a synthetic sensor panel to explain Qt signals, slots, QObject thread affinity, bounded sample buffers, connection states, and controlled shutdown behavior.
- [Separate page and background responsibilities in a browser extension](https://yishto.com/en/learn/application-platforms/browser-extension-study-assistant/index.md): Design a user-triggered Chrome page-note assistant with separated contexts, narrow permissions, validated messages, and plain-text results that cannot trigger privileged actions.
- [Connect commands, files, and task notes in a VS Code extension](https://yishto.com/en/learn/application-platforms/vscode-extension-task-notes/index.md): Build project task notes by connecting command declarations, extension lifecycle, scoped storage, Workspace Trust, URI handling, and cancellation-safe writes.
- [Understand Godot scenes and state through a small game loop](https://yishto.com/en/learn/application-platforms/godot-small-game-loop/index.md): Build a square-collection exercise around Godot scenes, input actions, physics updates, and game state, checking pause behavior, repeated collisions, and restart cleanup.
- [Connect pages, identity, and backend data in a mini program](https://yishto.com/en/learn/application-platforms/wechat-learning-miniapp/index.md): Design a learning-progress mini program with page boundaries, server-side login exchange, record authorization, network-response handling, and device domain validation.
- [Understand token state and confirmation on a local chain](https://yishto.com/en/learn/application-platforms/local-chain-token-lab/index.md): Use a local development chain for exercise receipts, explaining ERC-721 identity, mint authorization, transfers, receipts, and the distinction between metadata and on-chain ownership.
- [Identify platform-specific checks before releasing an app](https://yishto.com/en/learn/application-platforms/application-release-and-maintenance/index.md): Separate build, installation, submission, and review states across mobile, desktop, and extensions, with artifact records, accurate permission disclosures, trusted updates, and recovery tests.
