Challenge
The system had to connect many different data types and workflows without overwhelming the interface, preserve each domain's history and give AI access only to the relevant user context.
PERSONAL SYSTEM / HEALTH TRACKING / AI ASSISTANT
A personal system connecting body, plans, work and inner practices
Levana is a mobile PWA for managing everyday life. It combines health trackers, journaling, plans, work tasks, clients, content, a crypto portfolio, personal practices and several context-aware AI conversations in one private space.

Why Levana was created
Why Levana was created
Health, habits, personal notes and work projects usually live in separate applications and never form one picture. Levana organizes them around one user so daily actions, progress and AI assistance can share relevant context.
Who the system serves
The product is designed for someone who tracks wellbeing, builds discipline, runs projects and preserves personal practices at the same time. Mobile navigation makes the main actions available in an installable PWA experience.
Solution
We built a Next.js PWA and Fastify backend with PostgreSQL. Modules are separated by domain while sharing one profile and authentication model. The AI layer maintains distinct channels for everyday coaching, practices and crypto context, while a Telegram bot delivers user-connected reminders.
Capabilities
Product capabilities
The capabilities support one operating scenario and share common state, control and analytics.
Plans and discipline
The home view, daily plans and task manager organize today's actions, recurrence, ordering and completion.
Health tracking
Water, food, weight, measurements, workouts, supplements, cycle, fasting and other entries form a self-tracking history.
Journal and progress
Personal entries, attachments, goals, wishes and charts connect life events with changes over time.
AI coach
Conversation uses profile and current context, accepts food images and can create a structured meal plan or workout.
Work workspace
Clients, groups, services, transactions, content plans and tasks support personal operations.
Contextual spaces
Crypto portfolio, P2P records, meditation, practices and totems have dedicated views and specialized AI channels.
Outcome
Outcome
Levana turns disconnected trackers, notes and work tools into one personal system. The user gets a shared dashboard and history, while AI and reminders operate on real context from plans, health and projects rather than as separate utilities.
