About

360inAR

Read full description

360inAR turns photos from your album into a semi-transparent AR sphere that appears in front of your iPhone or iPad. From the outside, the sphere is translucent—but when you scale it up and step inside, you can view the panorama without transparency, as if you’re surrounded by the image. For the best first experience, start in a relatively spacious area and walk while holding your device. What’s New You can now export your AR sphere as a USDZ file. Save your creation and share it as an AR-ready object using the system share sheet. You can also choose the sphere texture format (JPG or PNG) and select the sphere size (20 cm or 3.6 m diameter). Placement & Fine Tuning After the sphere appears, you can fine-tune its position for a comfortable AR experience. Because AR takes a bit of practice to understand the relationship between scale and distance, fine adjustments are designed to work near the initial placement. To place the sphere somewhere else, move to the desired location and triple-tap to reset the position. How to Use Gesture Controls •Pan (drag): Rotate the AR sphere •Pinch: Resize •Single tap: Stop rotation •Double tap: Double the size each time (resets after exceeding 50×) •Triple tap: Reset position •Long press: Fine-tune height and horizontal position Buttons •Top right: Instructions •Bottom left: Select photo •Bottom center: Screenshot •Bottom right: Share (Export USDZ / Save / Share) AR Specifications •No need to scan floors or walls •The AR sphere appears based on your iPhone/iPad position AR Behavior in This Version •The AR sphere appears slightly below center so it sits near the middle of the display when you hold your iPhone/iPad naturally. If you hold the device at an upward •angle, the sphere may look cropped at the bottom of the screen. In that case, the sphere is positioned below your current view.
