Some thoughts are too heavy to keep inside. Sometimes, they stay there because saying them out loud feels impossible. You don't know where to begin. You don't know who will understand. And sometimes, you worry you'll be judged before you're even heard. So you stay quiet. We built The Open Diary for moments like these. A quiet place where you can write whatever is on your heart. No pressure. No pretending. No need to have the right words. Just you, your thoughts, and a community that listens. More than 58,423 people have already shared their thoughts here. Some came looking for advice. Some simply wanted someone to listen. Many just wanted to feel a little less alone. With Open Diary, you can: • Write freely, anytime. • Choose whether your diary stays private or is shared with the community. • Edit your diary whenever you want. • Read real stories from people around the world. • Comment, react, and support others. • Receive thoughtful replies from people who understand. • Tag therapists in your diary when you'd like professional guidance. • Book sessions with experienced therapists whenever you're ready. Every diary shared with the community is first reviewed by our AI to help reduce spam, scams, and harmful content, creating a safer space for genuine conversations.

Kiori was built because we were tired of wellness apps that felt like part-time jobs. You know the ones. Aggressive streak warnings. Color-coded shame charts. Pop-ups asking you to rate the app for the third time this week. Half the features are locked behind a subscription. Your most personal data is sitting on someone else's server. Kiori is different. It is calm, beautifully designed, and quietly capable. It does the things you actually need a wellness app to do, and then it gets out of your way. What you can do: Track your meals without friction. Search a comprehensive nutrition database and log calories, protein, carbs, fat, and fiber in seconds. No barcode hunting if you don't want to. No premium tier hiding the food you ate. Stay hydrated. Tap a glass, watch your bottle fill, and get gentle hourly reminders if you're falling behind. The bottle visualization is genuinely satisfying. Remember your supplements. Set the exact times you want to be reminded, and Kiori will nudge you, even when the app is closed. Move your body, your way. Steps, distance, and active minutes sync automatically from Apple Health. Log running, cycling, lifting, yoga, or whatever else you do, either manually or straight from your workouts in Apple Health. Take on real challenges. Build a No Sugar week, try 75 Hard, or invent your own. Mark each day off and watch the streak quietly grow. Start mornings with something kind. A daily affirmation, gently animated. It sounds small. It is not small. Keep an eye on the bigger picture. A soft, visual BMI indicator and a personalized calorie goal based on your own numbers. No harsh judgment, no fat-shaming charts. See it all on one screen. A clean daily dashboard pulls your calories, water, protein, steps, and streaks into one calm view. No scrolling through ten tabs to find out how your day is going. About your data: Everything you log in Kiori stays on your iPhone. Nothing is uploaded. There is no account to create. No company database holding your weight, your meals, or your routines. Apple HealthKit is opt-in, and you can turn it off at any time. It is your wellness journey. We never forgot that. Why Kiori: Most tracking apps treat your body like a project to be optimized. Kiori treats it like something to be cared for. Every screen, every animation, every notification was designed to feel quiet. Encouraging without being loud. Useful without being demanding. The kind of app you can keep on your home screen for years without resenting it. That is what we set out to build, and that is what Kiori is. Requires iOS 16.0 or later. Made for iPhone. Built by two people who really wanted this app to exist.
