Mars and more lets users get Sun, Moon, Mercury, Mars and Venus sign readings and calculate charts. For support contact lanternbugs at gmail. Anyone wishing to reach out and share any thoughts on the app, and doesn't want to just review, or astrology is welcome to contact the support mail as well. The lanternbugs name comes from its first use as a bug testing account for my first app, Lantern Chess.
