SREDA365 is not a habit tracker. It's not a mood diary. It's a personal OS for intentional growth: in the morning you set the direction for your day, during the day you pause to check in, and in the evening you reflect and extract a lesson. At its core is your Orientir — who you are, where you're going, and how. It lives on your home screen and quietly brings you back to what matters every time you open the app. — Morning practice: sleep quality, main task, possible obstacles — Midday pause: what you were doing, does it move you toward your goal? — Evening reflection: day summary, emotions, energy, key lesson After a few weeks, the Statistics screen shows your personal trends. The Lessons feed collects your evening insights — a private knowledge base built entirely from your own experience. Questions are fully customizable: toggle built-in ones, add your own, reorder them in the editor. All data stays on your device. No account required. The app is free. You can support the project voluntarily from within the app.
