All you need to know about the Sun & daylight. Much enhanced version of SunCalc. Track Sun position for any location/date, get exact times of sunrise,sunset,dawn, dusk,twilight levels, day/night length. Calculate shadow length & angle. See day/night length graphs for the entire year. Use Sun & Shadow angle compass. Monitor when the Sun gets above & below selected altitude. Get real-time astronomical data of the Sun.

The oldest Biorhythm calculation app for smartphones (written in early 2002 for the Nokia 9210 Communicator) ported to Harmattan. Provides features missing from other apps of this kind for the N9: storing data of two persons and quickly switching between them, biorhythm interpretation, warning about critical days, scrollable graph, information about cycles (completed, day of current cycle, etc.) and more. Accurate and easy to use.

Easily locate stars,planets,constellations,galaxies,nebulae,asterisms,meteor radiants. Just select an object and the app will instantly show you where it is in the sky. Turn in the direction and altitude shown and there you have it! You've heard about Sirius,Vega,Pleiades,Andromeda,but were never able to find them? Can't locate Venus or Mars? Not anymore. Also calculates lots of real-time astronomic data for each object. REQUIRES PR1.1 or newer firmware. Doesn't work on OBSOLETE PR1.0

All important Sun info for any location and date: times of sunrise, sunset, dawn, dusk, transit & altitude, various twilight levels (civil, nautical, amateur, astronomical), day & night length (also vs. previous day & solstice), shown both numerically and on a real-time updated graph. See Sun's path through the sky on any day at a glance, be informed about all events. Supports both GPS and manual data. The most advanced Sun app for Symbian & MeeGo.

Advanced Moon tool. Provides rich real time calculations of Moon phases, age, illumination, distance, apparent size, coordinates (right ascension, declination, ecliptic latitude and longitude), azimuth, elevation, moonrise and moonset times, perigees and apogees, Moon Compass, and more. Uses GPS to get your location, but allows entering coordinates manually as well. Compatible with Symbian ^3, Anna and Belle with nHD screen. Compass requires magnetometer sensor.
