A diary you don't have to write. Speak for a minute, add a photo and how you feel, and your day becomes a memory bubble you can revisit for years. ONE MINUTE A DAY, JUST FOR YOU Do you like the idea of keeping a diary, but it always felt like too much effort? One Minute Diary is made for exactly that. You simply talk for a minute, or write if you prefer. A gentle daily question helps when you don't know where to start. Over time, your days grow into a collection of memories that you can wander through, years from now. WHAT YOU CAN DO • Capture a memory in a minute: speak or write, add a photo, choose your mood • Travel back in time and rediscover forgotten moments, with smooth animations • Capture every day, or only the special ones, whenever it feels right • A daily mindfulness question, also as a gentle reminder • Choose the colors you like • Encrypted or unencrypted backups you keep yourself PRIVATE BY DESIGN Your memories stay on your iPhone. No account, no ads, no tracking. THE STORY BEHIND THE APP I'm Adrian, a psychologist (MSc) and iOS developer. I always wanted to keep a diary, but I never managed to stick with it. So I built the diary I would actually use: quick, calm, and a little playful. After a while I realized I'm not the only one with that problem, so I'm sharing it with you. If you enjoy the app, a 5-star rating helps me a lot. And if you have feedback, you can write to me directly from the settings. I read every message. Adrian
