Rediscover your photo library through the places you’ve been. MinusBox turns your photos and videos into a map of memories, helping you browse your library by city and review place-based media stacks with more context. Instead of starting with crowded file categories, MinusBox lets you begin from the places, trips, and life moments that your photos represent. On the map, each city can show photos and videos connected to that location, including repeated moments that are easier to review together. Open a city to browse media from that place, compare related moments, and decide what to keep or move to Bin. MinusBox also includes practical speaker sound modes for everyday phone care. When your speaker sounds muffled after daily buildup, rain, or splashes, you can play guided sound patterns through your device speaker. These modes do not require microphone access and do not record audio. Key Features -Map-first photo and video browsing by city -Place-based media stacks -Repeated moments grouped by location -Speaker sound modes for dust and water situations -Local media processing on device Why MinusBox Is Different Most gallery tools start with generic categories. MinusBox starts with your memory map. It helps you revisit the places you’ve been, review related moments from each city, and organize your photo library with more context. Privacy-Friendly by Design MinusBox is designed to process and organize your media locally on your device. Your original photos and videos are not uploaded for media review, and no account is required. Support & Policies Questions or feedback?
