Compass is a desktop application for casting traditional wheel charts at the heart of astrological practice: Mundane, Natal, and Transit. Each chart opens in its own window, so you can keep several on screen and compare them side by side.
Every control sits beside the wheel rather than behind a dialog. Change the frame, the bodies, or the aspects and the chart repaints immediately—so reading a chart and refining it become the same motion.
Find your bearings with Compass. A 15-day trial license will be automatically created when the application is installed for the first time.

A Transit chart combines the two—plotting transiting positions against a natal reference and matching the aspects between them, the core technique for timing and forecasting.
Step a chart forward or backward in units from seconds to years and watch aspects form and separate. Daylight-saving transitions are handled correctly at every step, so the moment you are reading is always the moment you intended.
Cast in the tropical or sidereal zodiac, from a geocentric, topocentric, or heliocentric origin, against the ecliptic or equatorial plane. Turn the wheel to Horizon or Zodiac orientation and divide it with any of eleven house systems, from Placidus and Koch to Whole Sign and Regiomontanus.
Plot up to 25 bodies—angles, planets, the lunar axis, asteroids and centaurs—grouped for quick selection and saved as named presets. Each chart type keeps its own aspect definitions, so you can give Mundane, Natal, and Transit work their own angles, orbs, and chord colors.
Double-click an event row in an Aquila study and the matching Mundane or Transit chart opens in Compass, its moment and frame already set. The event you found and the sky that produced it are one gesture apart—no re-entering dates, no switching context.
Locations and Natal Records live in a library shared with your other Rhythm Seven applications, so a place or a birth record entered once is available everywhere, and records import and export as CSV.
