All the weather of your life, at a glance! "MeteoLife" is the only application that provides a synthetic vision for your astrological and biorhythm informations. Want to know a little more about your week? No problem, one click is enough! Astrological predictions are made on the basis of the position of the stars, while the biorhythm is built upon our life cycles. Because Astrology is a complex field, specialists helped us to synthesize the relationships between the influence of the stars and the impact on areas of our lives, such as Love, Work and even Money. Calculating biorhythms is much more simple: there are 3 main cycles and 4 secondary cycles. The three main cycles are the cycles of Physical, Emotional, and Intellectual, respectively, 23 days, 28 days and 33 days. The four sub-cycles are the cycles of Spirituality, Awareness, Aesthetics and Intuition, respectively 53 days, 48 days, 43 days and 38 days. Be careful with the interpretation of the results, because in parallel, the positions of the stars can announce things that seem contradictory with your biorhythm. For example, you see a beautiful sun for your Health, but your biorhythm tells you that you are only 10 % of your Physical cycle! This is however not contradictory : you can be in a favorable conjunction of the planets for your health, but physically tired. Bonus! • Your Color of the day • Your Number of the day • Your Letter of the day
