SunCalc.net, by Oleg Shanyuk, is an iPhone and iPad utility that predicts solar positions for planning outdoor activities. The app computes sunrise, sunset, solar noon, azimuth and altitude, and simulates sun movement with a timeline slider for any date and coordinate. It includes twilight phase timing, an interactive map for choosing coordinates, and a live compass to orient the device. Photographers, architects, gardeners, and hikers benefit from minute-by-minute light analysis and offline solar calculations.

Calculates exact solar timings at any chosen coordinate

Interactive world map selection feeds the calculation engine to produce precise sunrise, sunset and solar noon times, plus solar azimuth and altitude. The app reports detailed twilight timing, including:

• civil twilight
• nautical twilight
• astronomical twilight

Minute-by-minute simulation and on-site orientation for field planning

The timeline slider lets users step through the sun's path in minute increments to observe changing light angles across a day. Live compass integration helps align the device for on-site assessment. Core astronomical formulas run locally on the device, so timing calculations do not depend on cloud services; map background imagery may still need a network connection to display tiles.

Targeted at creatives and field planners with modern device requirements

The app addresses photographers, architects, gardeners and outdoor hobbyists who plan around natural light. The interface is ad-free and optimised for recent iPhone displays, and the developer supports current iOS releases; the app requires iOS 16.4 or later and runs on both iPhone and iPad. This focus supports a compact, mobile planning workflow for field use.

A focused planning tool that rewards pre-trip preparation

The app maintains a high App Store rating and users note its clean design and focused utility, which supports methodical planning routines. The interface is available only in English, and interactive map tiles typically require a network connection to load. Tip: cache the map area and weather overlay while connected before you go on site to keep planning uninterrupted.
