Step inside the panoramas you forgot you took. You took those panoramas because the view was breathtaking. Then they disappeared into your camera roll, a thin sliver among thousands of photos. PanoMemo brings them back. Tap one and you're inside it - swipe to look around, tilt your phone to follow the scene, pinch to zoom. The full resolution is preserved. It feels like being there again. [ Look around, smoothly ] Pan, pinch, and tilt to explore every angle. No goggles, no special hardware - just your phone and the photos you already have. [ Know the mountains in your photo ] Find the names of the peaks in your landscape panoramas, right on the spot. Long-press a mountain to see name candidates, or browse the peaks that should be visible from where you stood. Works for mountains worldwide. [ Labels that land on the peaks ] PanoMemo figures out which way your photo was facing, so name labels sit right on the peaks you see. If the sun is in frame, just tap toward it to fine-tune. [ Point your camera at the peaks around you (Live AR) ] Hold your camera up to the mountains and the names, elevations, and directions of the visible peaks appear right over them. "Which mountain is that?" - solved instantly, on a lookout or mid-hike. [ See the sun and moon, too (Live AR) ] Point your camera at the sky to see where the sun and moon are right now, plus their arc across the day - where they rise and set. Slide the time to preview their future positions (the moon shows its phase, too). Great for planning a shot or catching a sunrise. Precise astronomy means it works wherever you are in the world. [ Name the unnamed peaks (My Peaks) ] Give your own names to peaks the database doesn't know. They show up in candidates, lists, and the map - turning "the pointy one behind my house" into your personal record of the mountains. [ Build your peak collection ] Every peak you name joins your collection - building a record of how many you've named, and across how many countries. [ Relive where you shot it ] The Map shows your panoramas as thumbnail pins, right where you took them. Tap a pin for the place name and date, then open it in the viewer. Filter by country, or jump from the place list. Photos without location? Drop them on the map by hand. (The map only reads the position already saved in each photo.) [ Share the whole scene as a video ] Generate an auto-sweeping video of any panorama and save it to your library, in Standard (1080p) or full original resolution. [ Stay organized ] Star favorites, group into albums, and filter by year and month to dig up old shots in seconds. [ Swipe to clean up ] Swipe to sort panoramas into keep or delete, then remove them all at once - with a clear view of the storage you'll free up. Deleted photos stay recoverable in "Recently Deleted." [ Drop pins to remember ] Long-press any spot inside a panorama to leave a named pin - "the corner table by the window," "the lookout." Save frequently used pins as templates for one-tap reuse. [ Privacy-minded ] - Your photos never leave your device - No account needed - Never asks for permission to track you (Only place-name lookup, the data for the mountain features, and export-time ads use the network. Your photos and exact location are never sent, and terrain downloads always ask first.) [ Every feature is free ] Pins, albums, peak finder, Live AR and cleanup are all free. Ads appear only when you export an image or video - a single one-time purchase removes them forever. No subscription, ever. [ Compatibility ] - iOS 17 and later - Universal: iPhone and iPad - Japanese and English (auto-switches with system language) PanoMemo works with panorama photos taken in the built-in Camera app's Panorama mode. โ€” Sample panorama images: Designed by Magnific (magnific.com), Pexels (pexels.com)
