Witha lets you place virtual objects in your room and enjoy viewing them anytime. Enjoy everyday life surrounded by your favorites. Witha remembers the position and orientation of the objects you place and restores them when you return. You can place multiple copies of the same object and resize them to decorate your room freely with your favorite 3D objects. Take photos of your decorated room and share them with friends or on social media. Saved object arrangements can be managed as multiple placement sets. Use different sets for different rooms, or switch between arrangements in the same room to enjoy your favorites in different ways depending on your mood. ■ About Objects Witha uses 3D objects in the USDZ format. You can add USDZ files from Files, other apps, or AirDrop. On LiDAR-equipped devices, you can also scan real-world items and create 3D objects directly in Witha. For higher-quality results, photograph an item from multiple angles using Witha, then create a 3D object with Witha Studio for Mac. ■ Multi-Device Support Objects placed on an iPhone can also be enjoyed on the larger screen of an iPad. Data is synchronized through iCloud Drive across devices signed in with the same Apple Account. ■ Subscription Witha is free to use with some limits. A subscription raises the limits for objects, placement sets, and photo captures. ■ Intellectual Property Rights When using 3D objects or scanning real-world items, please respect copyrights, portrait rights, trademark rights, and other applicable rights. If you use content owned by third parties, ensure that you comply with the rights holder’s permissions and terms of use. Do not distribute, share, or sell 3D objects created from protected content without permission from the rights holder.
