Happy Diary is a simple place to keep the moments that made you happy and meet them again after time has passed. You do not need to write a long diary every day. A title is enough to save a memory, and you can add as much or as little as you want. Keep each memory with: • Photos • Notes and stories • Categories • Keywords for feelings and meaning • Flexible memory dates • Local MP3 music or a YouTube video Your memories are stored locally on your device by default, and no account or login is required. REDISCOVER MEMORIES OVER TIME Happy Diary is not designed to pressure you into recording something every day. With the optional Revisit Memories feature, the app can occasionally bring back a good memory you have not seen for a while. Choose the rhythm that feels right for you: • Occasionally • Weekly • Monthly You can also keep reminders completely turned off. The same memory is not shown too often, helping each rediscovery feel special. FIND YOUR MEMORIES EASILY Search and browse memories by title, notes, category, keywords, or when the memory happened. As time passes, your archive becomes a personal collection of moments worth keeping. ADD PHOTOS AND MUSIC Add up to 10 photos to a memory and choose a favorite image. You can also attach one local MP3 file or connect a YouTube video that reminds you of that moment. BACK UP YOUR MEMORIES Create a local backup that includes your memories and attached media, and restore it when needed. SIMPLE BY DESIGN • Only the title is required • No account or login required • Local-first memory storage • Optional low-frequency reminders • Local revisit history • Light and dark themes • Multiple languages supported Good memories do not need to be seen every day. Sometimes, meeting them again after enough time has passed makes them feel even more meaningful. Keep the moments you want to remember with Happy Diary.
