Aspects & configurations
Trace grand trines, T-squares and other patterns directly on the wheel. See the supporting aspects alongside each pattern.
Features
Tools for reading charts.
Natal charts
Read the wheel and its aspects.
Keep positions, aspects and configurations beside the wheel. Select a connection to highlight it on the chart.
Traditional techniques
Bring dignities, lots, midpoints and planetary periods into your reading alongside the natal chart.
Client view
Hide private notes and your client list while sharing the chart on a call.
Import your charts
Import Solar Fire and Astro Gold chart files, Quick*Charts exports, and AAF files from astro.com. Preview birth details and choose which charts to add.
Keep charts, notes and past work together on your computer.
Relationships
Compare charts.
Explore the connections between two charts with synastry, or consider the relationship through a composite or Davison chart.
View two charts in a biwheel, or compare several charts in a multiwheel.
Transits & timing
Explore planetary cycles.
Map the months ahead, revisit a turning point, or explore the current sky against a natal chart. Ephemeris Lab has no AI features. It calculates the charts and timing; you bring the interpretation.
Live transits
Read the sky now, then move through time to follow an approaching aspect or watch a pattern unfold.
Planetary returns
Find solar, lunar and Saturn returns, or explore other planetary cycles.
Event search
Find aspects, sign ingresses and stations across a date range, with each result shown on the timeline.
Progressions & solar arcs
Use secondary progressions and solar-arc directions for long-term timing.
Share & print
Chart images for videos and posts.
Export a styled wheel image with room for a presenter or captions in your composition.
Image formats
Story 9:16 for vertical video. Portrait 4:5 or square 1:1 for a post.
Share styles
Choose a share style separately from your app theme, including for relationship and multiwheel charts.
