Generated based on Discovery Session (March 28, 2025) and Research Analysis (March 29, 2025)
Last Updated: March 29, 2025
1. Problem & Solution
Problem Definition
Users lack a simple, aesthetically pleasing way to visualize the sun's current activity (solar weather) in real-time, particularly those curious about potential correlations between solar phenomena and personal emotional states or world events.
Problem Importance
There's a niche interest, supported by some research suggesting links between solar activity and human well-being/behavior. Existing solutions often provide complex data or alerts, not a simple, reflective visual experience.
Differentiation
Heliodore differentiates through its extreme simplicity, focus on a beautiful, intuitive JavaScript-animated visualization, and singular purpose. Unlike competitors (e.g., Space Weather Media Viewer, Solar Alert App) that offer detailed data, alerts, or educational content, Heliodore provides an immediate, glanceable, aesthetic representation of the sun's state.
Value Proposition
Offers a beautiful, simple, and real-time window into the sun's current activity, allowing users to satisfy their curiosity and potentially connect personal feelings or observations with solar phenomena in an elegant, non-technical way.
2. Features & Functionality
MVP Features
- Real-time data fetching from reliable solar APIs (e.g., NASA SDO for images, potentially DONKI for specific event data like flares).
- A core JavaScript-based animation visualizing the sun's current state (e.g., color changes for activity levels, visual representation of sunspots based on data).
- Minimalist User Interface (UI) displaying only the sun visualization upon opening the app.
- Availability on both iOS and Android platforms.
Future Iterations
While the core concept emphasizes simplicity, potential future features could include:
- Optional subtle notifications for major solar events (configurable).
- A simple historical view (e.g., swipe back 24 hours).
- Sharing the current visualization.
Note: Any additions must carefully preserve the core simplicity.
Key Value Features
The real-time, aesthetically pleasing, animated visualization of the sun's current state is the single most valuable feature.
Primary User Action
Open the app and observe the sun visualization.
3. Target Audience
Primary Users
Individuals interested in astronomy, space weather, mindfulness, or those curious about the sun's potential influence on emotions and the environment. Likely includes hobbyists and enthusiasts rather than scientific professionals.
Demographics & Psychographics
Global audience; age range likely broad but potentially leaning towards adults interested in science, nature, or alternative wellness concepts. They value aesthetics, simplicity, and a non-intrusive experience.
Pain Points
Lack of an easy-to-understand, visually engaging tool to quickly check the sun's current state; finding existing space weather apps too complex or data-heavy for casual curiosity.
Technical Proficiency
Low to moderate. Users should be comfortable downloading and using standard mobile apps but do not require scientific or technical expertise.
4. Market & Competition
Existing Solutions
- Space Weather Media Viewer (NASA): Offers images, data, and educational content.
- Solar Alert App: Provides alerts, simulations, and data.
- SpaceWeatherLive: Website/app focusing on detailed real-time solar and auroral data.
- Various general weather apps sometimes include basic space weather info.
Competitive Analysis
Strengths of Competitors: Provide comprehensive data, alerts, forecasting, educational resources. Established user bases.
Weaknesses of Competitors: Can be complex, data-heavy, overwhelming for casual users; may lack aesthetic focus.
Unique Advantage
Heliodore's advantage lies in its extreme simplicity, focus on visual beauty, and intuitive presentation. It serves the niche desire for an ambient display of solar weather rather than a detailed analytical tool.
Market Size
Niche. Initial user estimates are low (around 100 users), suggesting a small, specific market. However, growing interest in space weather (e.g., due to solar cycle peaks) could provide opportunities.
5. Business Model
Revenue Strategy
One-time purchase on the iOS App Store and Google Play Store.
Pricing Strategy
Low price point, $0.99 or $1.00, reflecting the app's simplicity and niche appeal. Aims for accessibility rather than significant revenue.
Resource Requirements
Development: Requires mobile app development expertise (iOS/Android, potentially cross-platform like React Native or Flutter), JavaScript animation skills, and API integration experience. Likely 1-2 developers for MVP.
Maintenance: Ongoing monitoring of API availability/changes, OS updates, minimal server costs (if any needed beyond API calls).
Marketing Strategy
Minimal/Organic: Rely on app store discovery, potentially targeting relevant online communities (astronomy forums, mindfulness groups) with simple announcements. Focus on clear screenshots/videos highlighting the visual appeal. Given the low user target, extensive marketing is not planned.
6. Success Metrics
KPIs
- Number of downloads/purchases.
- App Store ratings and reviews (qualitative feedback on simplicity/beauty).
- Session duration/frequency (understanding if users check it regularly, even if briefly).
- Crash reports/stability metrics.
Growth Goals
Achieve the target of ~100 downloads/purchases within the first 3 months post-launch. Positive user reviews validating the core concept.
Feedback Mechanisms
Primarily through App Store reviews. Optionally, a simple in-app link to an email address for feedback.
Timeline
To be defined. Given the simplicity and reliance on existing APIs, an MVP could potentially be developed within 2-4 months, depending on resource allocation.

Expected outcome: User quickly satisfies curiosity about current solar state through beautiful visualization, reinforcing the app's value for frequent brief interactions.
5. Implementation Considerations
MVP Delineation
The Minimum Viable Product for Heliodore consists of:
- Core solar visualization functionality (US-001 through US-007)
- Minimal interface and basic interaction (US-008, US-009, US-012)
- Essential data integration (US-014, US-016, US-017, US-018)
- Cross-platform availability (iOS and Android)
- Critical performance requirements (launch speed, resource usage, animation performance)
Technical Complexity Assessment
Highest technical complexity stories:
- US-001 (Core visualization) - Requires skilled JavaScript animation development and careful performance optimization
- US-014 (Data fetching) - Requires reliable integration with external APIs and proper error handling
- NASA API integration - Requires understanding NASA's API structure and potential limitations
