Key takeaways for Sunrise, Sunset
Where is it heading?
The solar utility market is consolidating around apps that offer high-frequency widget updates and lock-screen integration. Sunrise, Sunset remains stagnant, and the lack of recent development activity suggests a declining trend in relevance for the PM to address.
- The 1076-day update gap signals a maintenance-mode posture, which erodes user trust and visibility in the App Store algorithm.
The SWOT
- NASA SRTM elevation integration provides a defensible accuracy advantage
- Modern UI refresh could capture users from stagnant legacy utilities

The counter-intuitive read
The lack of updates is not just a neglect issue…
Read the full takeSince the last report: The app's competitive assessment shifted from a purely negative maintenance-mode critique to a nuanced view that frames the lack of updates as a potential indicator of a stable, feature-complete utility. No functional changes occurred, as the app remains in a three-year development hiatus.
Bottom line
Sunrise, Sunset relies on its unique elevation-based calculation mechanism, but the three-year development hiatus leaves the product vulnerable to modern, widget-focused rivals. Restoring basic OS compatibility is the only path to preventing total user churn.
