Experience SunCalc+ sunrise sunset dawn dusk twilight times, an Android utility from Jester Dev that maps solar events for outdoor planning. The app calculates sunrise, sunset, solar noon and three twilight phases using GPS-derived location and optional manual overrides for future dates. It displays Civil, Nautical, and Astronomical dawn and dusk in a single view, shows total day length, and supports GPS or manual location. Photographers, hikers, and campers get quick, on-device timing for planning golden hour and low-light windows.

How light is the app on modest Android devices?

SunCalc+ ships as a small package, approximately 5MB, which targets devices with limited storage. The installer size and design are described as optimised for older or modest hardware, so installation is quick and it occupies minimal persistent space. This makes the tool practical for users who keep limited apps on their devices or who prefer a compact utility that does not demand large updates.

What background data and permissions are required for full function?

The app requires internet permission to download a small amount of astronomical data used in calculations, a step noted as necessary for accuracy. In addition, runtime permissions are requested so the tool can access location data when available. This model means full functionality depends on network access at least once, and offline use may be limited until that astronomical data has been retrieved.

Who builds and maintains this utility, and how is it received?

Jester Dev is an independent Android developer that focuses on utility apps, including randomizers and alarm clocks as well as solar tracking software. The developer background explains the app's narrow scope and maintenance model. User reception is described as generally positive for simplicity, and reviews note an ad-free presentation that keeps the interface uncluttered for regular, practical use.

Is the interface suitable for quick field checks without deep astronomy knowledge?

The interface is intentionally compact and easy to read, prioritising rapid lookups over complex controls. This design supports immediate field checks where a single glance at timings is preferable to configuring advanced parameters. Casual users can consult the app for timing windows without learning astronomical concepts, while those needing specialized modeling should expect a simpler, focused tool rather than a full observatory-grade package.

SunCalc+ is a practical pick for field users who need quick solar timings

The app suits outdoor users who want straightforward, on-device access to timing information on modest Android phones. A clear trade-off exists: the tool emphasises compactness and quick checks rather than advanced astronomical modeling or deep configurability. For anyone needing fast reference times while outdoors, it performs reliably within that narrower scope, though specialists seeking exhaustive calculation options should look elsewhere.
