About

My Collection Book

Features
Read full description

Create the only collection that truly belongs to you. Most note apps help you write things down. Most photo apps simply store pictures. But memories, discoveries, and collections deserve more than that. Original Collection Book is a place to build your own personal collection. Whether you love insects, plants, animals, cafΓ©s, restaurants, minerals, books, travel, or anything else, you can organize everything into beautiful, searchable collections that continue to grow over time. A collection is more than a list. Every item has a story. Add multiple photos to capture different angles, changes over time, or memorable moments. Write notes so you'll never forget where you found it or why it mattered. Count how many times you've discovered the same thing and watch your collection grow with every new experience. Instead of disappearing into thousands of photos on your phone, every discovery becomes part of something bigger. ============================== Enjoy collecting ============================== Creating a new entry takes only a few seconds. Take a photo. Give it a name. Add notes whenever you want. Include multiple photos for each item. Track how many times you've encountered it. As your collection grows, you'll begin noticing patterns, remembering stories, and appreciating experiences you might otherwise forget. ============================== Rediscover your memories ============================== Your collection isn't just storedβ€”it becomes enjoyable to explore. Browse everything in a clean gallery. Open detailed cards for every item. View discoveries on a map and remember exactly where they happened. Sometimes you'll open the app to search for information. Other times you'll simply enjoy looking back through everything you've collected. Every visit brings back memories. ============================== Perfect for families ============================== Children naturally love collecting things. "What was this called?" "How many have we found?" Take pictures together. Write notes together. Watch the collection grow together. Over time, your collection becomes more than information. It becomes a shared memory you'll treasure for years. ============================== Create collections for anything ============================== There are no predefined categories. Create an insect encyclopedia. A plant journal. A coffee shop guide. A restaurant collection. A travel log. A mineral catalog. A wildlife record. A movie library. A figure collection. A personal photo journal. Or invent something completely unique. This app adapts to your interests instead of forcing you into someone else's system. ============================== Built to grow with you ============================== There are no limits to how many collections or entries you can create. Start with one idea. Add another tomorrow. Keep discovering. The goal isn't to finish your collection. The joy comes from watching it grow. Every photo becomes a memory. Every discovery becomes part of your story. Start creating your own collection today.
