Eclipse - Solar & Lunar is an educational tool for visualizing solar and lunar eclipses on a 3D globe across a 5,000-year timeline.
The App DNA
What makes this app unique?
The app removes the cognitive friction of interpreting complex Besselian elements by providing a visual, location-aware simulation of celestial events.
For Amateur astronomers, students, and eclipse enthusiasts seeking precise, scientifically-backed visualizations.
What does it look like?
Key features
Interactive globe allows users to scrub through time and observe the Moon's shadow path across Earth.
Database of nearly 12,000 solar and 12,000 lunar eclipses from 2000 BCE to 3000 CE.
Displays advanced data including Besselian elements, gamma, magnitude, and sidereal positions.
How much does it cost?
The app operates as a free, non-monetized educational tool supported by the Astronomical Society of India.
Velocity
Maintenance developmentnew contentUX improvementsinternationalizationShow more...
Eclipse - Solar & Lunar maintains a maintenance-level cadence, with only one release shipped over the last 35 days. The latest update focused on expanding the app's scope to include lunar events and improving the globe visualization. Development appears to be feature-driven rather than event-based, with no evidence of a recurring live-ops schedule. Future updates are expected to follow this infrequent, feature-focused pattern.

Key takeaways for Eclipse - Solar & Lunar
Where is it heading?
The market for educational astronomy tools remains stable, with users prioritizing scientific accuracy over frequent UI updates. Eclipse - Solar & Lunar is well-positioned to retain its core audience by focusing on the requested future event projections, which would solidify its utility for long-term planning.
- The latest release added lunar eclipse tracking, which aligns with user demand for comprehensive celestial event data.
- The maintenance-only release cadence (35 days since last update) limits the ability to address recurring requests for future projections.
The SWOT
- 5,000-year catalog creates a deep reference barrier
- 3D globe visualization simplifies complex orbital data
- Integrating future event projections addresses top user requests
- Expanding interactive animations increases user engagement
Next best moves
Ship future event projections because users request long-term planning tools → increase session frequency
The counter-intuitive read
The lack of monetization is a strategic advantage…
Read the full takeSince the last report: The app's strategic focus shifted toward addressing long-term planning needs via future event projections, while the FAQ now explicitly confirms the absence of monetization to build user trust.
Bottom line
Eclipse - Solar & Lunar secures its position through a deep, scientifically-backed catalog, but the current maintenance-only cadence risks stagnation. Prioritizing future event projections would unlock the long-term planning utility that users currently find missing.
