A little scene. A much bigger surprise. Discover wallpapers that turn a close-up into a whole new story when you explore the full picture. Duopaper pairs a focused folded preview with a panoramic expanded view of the same artwork. A tiny character can belong to an unexpected world; a quiet detail can be part of something wonderfully strange. Find a scene that feels right for your foldable or wide screen, then see what it has been hiding. Make room for your style. Browse Minimal, Illustration, Comics, 3D, Graphic, and Painterly artwork in HD. Preview the reveal, try a clock overlay, and adjust the preview focus before you choose. Keep favorites close and enjoy the collection offline, wherever inspiration finds you. Save the complete image to your photo library, or share it with someone who would love the surprise. Everything is free, with no ads, in-app purchases, or account required. After saving, set your wallpaper manually with the included guide; folded and expanded views are previews, and system cropping or transitions may vary.

Warm Camera is a point and shoot camera with its look built in. Soft, warm and a little grainy, like the photos you love. What you see in the viewfinder is what you get, so there is nothing to edit afterwards. THREE HOUSE LOOKS Warm for golden light and everyday life. Cool for overcast days and neon nights. Warrrmmmm for when warm isn't warm enough. Applied live in the viewfinder, in photos and in video. POINT AND SHOOT Tap to take a photo. Hold the shutter for a quick video. Swipe up or down to brighten or darken. Each zoom stop is its own lens, so the camera never quietly switches on you. MADE FOR IPHONE DUO Fold it halfway and set it down: the picture stands on one half, the controls lie on the other. Unfolded, it becomes a landscape camera with the controls in your hands. Turn on Duo Preview and the person you're photographing sees themselves on the outer screen, look and caption included. STRAIGHT FROM YOUR LOCK SCREEN Add Warm Camera to your Lock Screen, Control Center or the Action button and it opens without unlocking. A GALLERY THAT KEEPS UP Your shots land in Photos and in Warm Camera's own gallery immediately after you take them. Swipe through, favorite, share or delete, all actions sync to the Photos app. The gallery loads and navigates blazing fast. A CAPTION THAT REMEMBERS Add a quiet caption to your photos and videos: the day, time, city and weather, the song playing or the one Shazam just named, a landmark nearby, your altitude, sunrise and sunset. Out walking all day? Add today's steps, calories burned and heart rate from Apple Health, or your scores from your Oura ring. MagicCaption picks the right line for the moment; pull the caption button for a new one, or build your own. Forgot it? Add one later from the gallery, dated from when the photo was taken. Warm Camera only reads your Health and Oura data, only after you connect it, and it stays on your iPhone except inside the photos you choose to share. SCANS QR CODES Point the camera at a QR code and tap the note that appears to open it. WARM CAMERA PRO No caption, or your own words in it. Make your own filters: drag one dot warmer, cooler, softer or crisper, or fine-tune every setting. Import LUTs and shoot through them live with our grain on top. Manual ISO, shutter speed and exposure lock while recording. 48 megapixel photos, and tall 9:16 photos and videos that fill the screen. Try it free for 7 days. PRIVATE BY DESIGN No account, no ads, no tracking. Your photos and your Health data stay on your iPhone.
