TimePassages
vertical specialistAstrology software for desktop and mobile.
Transit timing views that keep chart interpretation and date-level aspecting in one workflow.
TimePassages performs natal chart casting and ongoing transits from entered birth data, then visualizes timing around moving astrological factors. It focuses on transit timing workflows such as aspecting, progression-style computations, and theme-based date views built for repeated lookups.
The tool’s integration surface is less about deep developer APIs and more about repeatable chart configuration for consistent results across sessions. Output exports typically center on chart rendering and reporting formats suitable for personal or client writeups.
- +Transit-centric workflow reduces steps between chart and date-specific interpretation
- +Birth-data input supports time zone and DST normalization for consistent chart placements
- +Chart configuration can be reused for recurring analyses without rebuilding settings
- +Exportable chart visuals support client-facing writeups in common file formats
- –API and automation surface are limited compared with developer-first astrology tools
- –Complex calculations like house systems and star handling need careful manual configuration
- –Synastry and event-harmonic views can feel constrained versus specialist suites
- –Observability for failed ephemeris lookups lacks depth for troubleshooting

Best for: Fits when frequent transit timing work needs consistent chart settings and fast re-runs.
Astrology.com
vertical specialistAstrology content site with chart tools.
Synastry compatibility compares two charts with relationship-focused outputs linked to shared placements and aspects.
Astrology.com generates charts from entered birth details and computes placements used across multiple analysis modules, including natal, transit timing, and progressed charts. Interpretive content is organized around requested chart types, so users can switch views without rebuilding inputs. House system selection and zodiac mode choices are presented as configurable controls, which helps align calculations with sidereal or tropical preferences.
A tradeoff is limited automation for bulk processing and limited integration depth for external pipelines, because the product is oriented around interactive chart generation rather than API-driven throughput. The best fit is recurring personal use where users repeatedly check transits, watch lunar phase tracking, or compare synastry for relationships. It also works for writers who need quick export outputs like SVG, PNG, or PDF for published visuals.
- +Chart modules cover natal, transits, progressed charts, and solar returns
- +Interpretations remain tied to computed placements and aspects
- +House cusp enumeration and aspect rules are visible enough to sanity-check outputs
- +Export formats like SVG, PNG, and PDF support publication workflows
- –Limited bulk calculation tooling for high-volume ephemeris batch runs
- –No documented standard interchange formats for chart results at pipeline scale
- –Automation does not extend into custom rules or programmable orb logic
- –Ephemeris reference epoch and lookup provenance are not surfaced for deep audits

Best for: Fits when individuals or small teams need fast recurring chart and transit views without building integrations.
Co-Star
vertical specialistAI-powered astrology app for daily insights.
Daily interpretation engine that updates from ongoing transit timing with progressed and lunar context.
Co-Star supports natal chart casting from birth details and then uses ongoing transit timing to generate new guidance as conditions shift. It also includes progressed chart-style timing and lunar phase context so readers can track both everyday movement and slower cycles in one place. The product is less about choosing complex house systems or debugging chart math and more about producing consistent, interpretation-ready outputs.
A key tradeoff is that Co-Star prioritizes readability over parameter transparency, so advanced users who need full control over orb rules, ayanamsha settings, or house cusps enumeration may find the configuration surface limiting. Co-Star fits best for daily personal use and for teams that need standardized interpretation snapshots for clients, where consistent outputs matter more than deep model control.
- +Daily transit-focused readings derived from a natal chart
- +Progressed-style timing context reduces chart switching
- +Lunar phase signals add day-level texture to guidance
- +Clear UI keeps chart inputs and outputs tightly connected
- –Limited control over advanced calculation parameters
- –Less suited to batch analysis across many date ranges
- –Interpretations favor consistency over raw computation visibility
- –Exports focus on presentation rather than astronomy-grade data

How to Choose the Right Astrology Software
What separates astrology software options is how reliably they generate charts and handle calculation details like houses and time handling. The fastest way to judge fit is to check the criteria around calculation accuracy and chart options in a live sample.
Calculation accuracy for chart data
Why it matters
Calculation accuracy for chart data is where trust starts, because small differences in time and settings quickly change planet positions and angles. If the results don’t match published examples you already rely on, you’ll end up double-checking everything.
How to check
In the demo, enter a birth date/time and location you recognize, then compare the positions and key angles to an external reference you already trust or to examples shown in the documentation. Also try switching a single setting and confirm only the expected parts change.
House system choices and behavior
Why it matters
House system choices and behavior matter because house cusps drive interpretation and life-event timing. If the tool doesn’t treat the house system consistently, your chart outputs won’t match how you read.
How to check
On a sample chart, switch between at least two house options and confirm the tool updates cusps and house placements immediately. Ask how it displays cusps (and whether it shows the full set) before you commit to workflows.
Time zone and daylight saving handling
Why it matters
Time zone and daylight saving handling affects the chart as much as the birth time itself. If the software silently shifts times, two charts made from the same input won’t agree.
How to check
Use the demo to set a birth time near a DST transition and compare outputs when you toggle time zone assumptions (or enter UTC vs local time if available). Verify the tool shows what time it actually used.
Transits and progressions support depth
Why it matters
Transits and progressions support depth matters if you plan to do ongoing work, not just natal charts. Limited support can force manual work or workaround exports later.
How to check
Generate a transit or progression-style output for a single moving period and confirm the date range, sweep mode (if offered), and the list of key bodies match what the interface claims. Export or copy the results and check they stay consistent when you rerun.
Interpretation templates you can control
Why it matters
Interpretation templates you can control keep outputs consistent across clients and projects. If the software only offers fixed writeups, you’ll struggle to match your own wording and emphasis.
How to check
In the editor or settings area, create a small custom template for a chart section and generate the same chart twice with two different template settings. Confirm the differences appear in the output and you can save and reuse your configuration.
Chart export and data output options
Why it matters
Chart export and data output options matter when you need to keep records, share reports, or move results into other workflows. If exports are incomplete or inconsistent, you’ll lose critical details later.
How to check
Export a chart and verify the output includes the key computed elements you rely on (planet positions, angles, house cusps, and any chosen options). Then re-import if supported, or compare the exported numbers with what the on-screen chart shows.
Red flags
- The chart changes unexpectedly when you only touch time zone fields
- House placements don’t update consistently when switching house systems
- Exports omit key computed details you expect to reuse later
Fit by situation
- If you work from specific natal references you trust, prioritize Calculation accuracy for chart data.
- If you read heavily through house placements, prioritize House system choices and behavior.
- If you build ongoing client reports across dates, prioritize Time zone and daylight saving handling.
