The Challenge

Modern Life Is Out of Sync

Irregular sleep, artificial lighting, and inconsistent meal timing have disconnected people from their natural biological rhythms — causing widespread health issues that existing apps fail to address.

Existing apps focus only on tracking behaviour, not guiding it with science-based, actionable recommendations.
Sleep disorders and energy dips are rising, yet solutions don't align routines with natural environmental factors like sunrise and sunset.
No holistic platform existed to simultaneously optimise sleep, nutrition, exercise and work schedules around light cycles.
Wellness apps provide limited actionable guidance and do not account for seasonal variations in daylight hours.
Where existing apps fall short
Actionable Guidance 18%
Solar Alignment 5%
Holistic Scheduling 12%
Science Foundation 25%
Seasonal Adaptation 8%
Our platform was designed to address all five of these gaps simultaneously.
Our Approach

Guiding Behaviour, Not Just Tracking It

We designed a system that uses solar time, seasonal patterns, and circadian principles to proactively define when users should sleep, eat, work, and rest.

01
Location-Based Solar Engine
Integrates real-time GPS data to calculate exact sunrise, sunset, solar noon, and twilight for each user's geographic location and time zone.
02
Seasonal Rhythm Adaptation
Dynamically adjusts routines across seasons — longer sleep in winter, compressed windows in summer — mirroring natural environmental cues.
03
Proactive Daily Scheduling
Generates a complete personalised daily plan: wake time, meals, fasting windows, exercise periods, peak cognitive windows, and wind-down rituals.
04
Science-Backed Education
Embeds 800+ curated chronobiology resources to help users understand the biological reasoning behind every single recommendation.
Key Features

Built for Real Behaviour Change

Solar-Based Scheduling Engine
Automatically calculates daily routines using real-time solar data, ensuring every activity aligns with natural light cycles throughout the year.
Dynamic 24-Hour Dashboard
A circular visual timeline that segments the day into colour-coded blocks — sleep, meals, activity, and recovery — for instant clarity on daily flow.
Intelligent Notification System
Contextual reminders for morning light, meal windows, peak focus periods, and bedtime — delivered gently with nature-inspired sounds.
Seasonal Adaptation Logic
Adjusts schedules as day lengths change through the year, automatically promoting longer sleep in winter and shorter windows in summer.
Fasting & Nutrition Alignment
Structures eating windows between dawn and dusk to support metabolic health — aligning nutrition with daylight for optimal hormonal balance.
Educational Ecosystem
An extensive library of circadian science articles empowers users with the knowledge behind every recommendation, driving long-term adherence.

Challenges & Solutions

Problems We Solved

Challenge
Handling Complex Time-Based Logic
Mapping individual user routines to continuously changing solar cycles across diverse geographies and time zones while keeping calculations accurate.
Solution
Flexible Rule-Based Engine
Developed a dynamic scheduling engine that adapts routines in real-time based on location data, date, and user-defined anchor inputs — with graceful fallbacks for edge cases.
Challenge
Translating Science into Usability
Circadian biology is complex and intimidating. Making Nobel Prize-level science digestible and actionable for everyday users without oversimplification was critical.
Solution
Visual Systems + Contextual Cues
Designed simplified circular visual systems, colour-coded segments, and contextual notifications that explain the "why" at the right moment without overwhelming users.
Challenge
Sustaining Long-Term Engagement
Behaviour change is hard. Users often engage initially but drop off. Creating a system that sustains long-term habit formation was essential to the product's value.
Solution
Reminder-Based Reinforcement Loop
Implemented a daily interaction model combining timely reminders with educational reinforcement — ensuring users receive a reason to act and understand each nudge.

4.6★
App Store Rating
Users consistently praise the clear visual design, science-backed recommendations, and measurable positive impact on sleep quality, energy, and routine consistency.
Daily
High-Engagement Interaction Model
The notification-driven daily interaction model keeps users actively engaged — many reporting measurable lifestyle improvements within weeks of adoption.
800+
Science Resources Integrated
The educational ecosystem is consistently cited as a key differentiator, driving subscription conversions and long-term user retention across both platforms.
Learnings

Strengths, Gaps & Learnings

✦ Strengths
Strong scientific foundation grounded in chronobiology and peer-reviewed research
Unique solar-based scheduling approach not seen in competing wellness apps
High daily engagement through intelligent reminder-driven interaction model
Rich educational content that drives subscription conversions and user loyalty
Credible endorsements from cardiologists, sleep experts, and light researchers
Intuitive circular UI that makes complex biology immediately understandable
◌ Gaps & Future Opportunities
Limited wearable integration — HealthKit and Google Fit sync would enrich personalisation
No direct behavioural tracking; platform focuses on guidance over measurement
Steeper learning curve for users unfamiliar with circadian biology
Fixed single wake-time not suited for shift workers or variable schedules
No historical progress dashboard to visualise routine adherence over time
