Dianary is a hunting-planning and management brand offering an app for Android and the web. Designed to support hunters before, during, and after a hunt, it brings schedules, records, and practical tools together in one place, with information synchronized across devices. Its planning features include a hunting calendar, checklists, weather and solunar data, alerts, and activity reports. The management tools help users track budgets and expenses, ammunition, permits, personal and animal documentation, equipment maintenance, animal care, trophies, and warranties, as well as generate authorizations for other people.

In the field, Dianary can record hunting routes, mark and share points of interest, show area boundaries, support searches for injured game, calculate shared expenses, and provide navigation to hunting locations. Many features work offline, and the app can keep documentation accessible on a smartphone. Users can also record hunting results, sightings, photographs, and personal accounts to build a digital diary and trophy collection. Dianary provides hunting statistics and challenges, and offers a printed-book option for preserving hunting memories.
