See what the SceneView SDK can do, on your own iPhone or iPad, before you write a line of code. SceneView is an open-source 3D and augmented reality SDK for SwiftUI, built on RealityKit. This app is its demo: 48 screens, each one a working sample of a feature you can put in your own app. Every screen links to the source code that draws it, and most of them are only a few lines long. WHAT THE SAMPLES SHOW - 3D models β€” load USDZ and Reality files, play their animations, and orbit, pinch and zoom the camera. - Augmented reality β€” place a model on a table, hang it on a wall, track images and faces, or place it instantly without waiting for a plane. - Real-world blending β€” real furniture and passing people stay in front of virtual objects, and the light around you lights the model. - Lighting and materials β€” swap HDR environments and watch reflections and shadows change in real time. - Scene mesh, depth, physics, geometry, spatial audio and more. - Your own files β€” open a USDZ, Reality, STL, OBJ, PLY or 3MF file and see how the SDK renders it. FOR DEVELOPERS A 3D model on screen is one view, and AR placement is one call. Find the screen that looks like what you want to build, open its code, and copy it into your project. The SDK, the samples and this app are free and open source. github.com/sceneview/sceneview PRIVACY No account, no analytics, no tracking, no ads. Your models and the camera feed stay on your device β€” the camera is used only for AR, and nothing it sees is stored or uploaded. The one feature that reaches the network is the online model gallery, and only while you are searching it. Open source under the Apache License 2.0. https://github.com/sceneview/sceneview

About

HeiLock

Read full description

HeiLock helps you set gentler boundaries around app time. When it is time to stop, pause for a moment, cut down on short, mindless bursts of app use, and use apps with more intention. Key features: β€’ Session Limits Set how long an app can be used each time. When the limit is reached, usage is restricted automatically. β€’ Cumulative Limits Set a cumulative usage limit for one or more apps. When the set time is reached, usage is restricted automatically. When you select multiple apps, use β€œCombined Usage Time” to choose how time is counted: when enabled, usage time across the selected apps is combined, and the apps share a single cumulative limit; when disabled, usage is accumulated separately for each app. β€’ Allowed Time Windows Choose when an app is available. Outside those windows, usage is restricted. β€’ Custom Display Content Add your favorite photos or videos. When an app is locked, HeiLock can show the content you selected, making each pause feel a little warmer. β€’ Manage Multiple Apps Manage multiple apps at once and set different usage schedules for different apps. β€’ Passcode Protection Protect your settings with a passcode to prevent unwanted changes. β€’ Local Storage No sign-in, no ads, and all data stays on your device.
