Built by collectors, for collectors. katrlog is a flexible cataloging app for iPad that works for real-world collections—especially the ones that don’t fit into a pre-defined template. Most “collection” apps assume you collect one thing (DVDs, books, etc.) and force you into their fields. katrlog is different: you create categories, define the properties that matter to you, and then catalog quickly and consistently. GREAT FOR • Household insurance & home inventories (contents, valuables, equipment) • Natural history collections (specimens, fossils, minerals) • Highly variable collections (stamps, artifacts, memorabilia, mixed collections) KEY FEATURES • Category-based organization (Categories → Items) • Templates per category so you can reuse the same fields for consistent entry • Custom properties/fields you define (track the details that matter to you) • Add photos to items (full-resolution images stored on-device) • Fast search and browsing designed for large collections • Useful collection totals and summaries CUSTOMISED PROPERTY FIELDS No bar code? No problem. katrlog enables you to create your own unique code/ numbering system, and create your own unique templates, with property/ data fields that matter to you. Alternatively, you can use one of katrlog's pre prepared category templates. Enhance your cataloguing experience with your own personal touch. IN APP IMAGE CAPTURE katrlog allow for in app image capture using a built in camera function. Photograph your item, edit it, and save it all from in app. No need to import images from a camera roll or use generic 3rd party images. Capture your collectables and everything that makes them unique. ADVANCED SEARCH FUNCTION katrlog's advanced search function allows the user to quickly locate and access items within your collection. No need to scroll through endless items within your collection to find what you are looking for. Using our powerful key word search function will find what you are looking for in seconds. BACKUP & DATA PORTABILITY It's YOUR choice - works offline with open-design database, or online with iCloud sync across your devices! • Your data stays on your device (offline-friendly) • Easy to take your data with you: the database and images are accessible via Finder/iTunes File Sharing • Data is stored in an open, widely understood format (SQLite database + image files) OR • Initiate the database migration in settings, and enjoy iCloud backup and synchronization across your devices. How it works When you open katrlog, you’ll see your categories. Tap a category to view items or add new ones. If you create similar items often, set up a template once and reuse it to enter items quickly and consistently.
