What Is Astrograph (TimePassages) and How Is It Different from Ordinary Astrology Software?

Astrograph is the company behind TimePassages, an astrology software suite by astrologer Henry Seltzer. It runs on Windows, macOS, iPhone, Android, and in a browser-based online version, and it covers birth charts, transits, progressions, and chart comparisons with built-in interpretation text. Desktop pricing starts at $79.00, with a free download available and periodic sales (the site has advertised 30% off the Standard desktop edition). It suits two groups at once: beginners who want to click a chart and read an explanation, and working astrologers who need a full professional toolset.

What TimePassages actually is

TimePassages is not a generic term for astrology chart images — in this context, Astrograph is the publisher and TimePassages is the product. The site describes the goal as putting "astrology within your fingertips" through ease of use plus a full feature set.

Core capabilities across the product line:

• Birth charts — generate and read a natal chart, with a free chart offered as an entry point
• Transits — track current planetary movement against a chart
• Progressions — secondary progressed charts for longer-term timing
• Chart comparison — compatibility and relationship work between two charts
• Interpretations — in-depth written readings by Henry Seltzer, viewable by clicking a chart feature
• Glossary and learning material — for people still building vocabulary

Desktop vs. mobile vs. online

The same brand splits into three delivery modes, and the right pick depends on where you do your work.

The desktop edition is the one with a stated price floor of $79.00 and the one professional astrologers named on the site (Rob Brezsny, Alan Oken, Antero Alli, Lyn Borsodi) are said to use in its Advanced Edition. Mobile and Online lean toward convenience: the app description emphasizes birth chart exploration, daily transits, progressions, and compatibility, while Online adds a dashboard, saved charts for friends and family, and settings for house calculations, displayed points, and aspect options.

How it differs from free chart websites

Free chart generators are usually good at one thing: producing a chart image from birth data. TimePassages differs in a few concrete ways:

• Interpretation is built in, not bolted on. Clicking a chart element surfaces Seltzer's written reading rather than sending you elsewhere.
• Charts persist. Online and desktop both support saving charts, so you build a library instead of re-entering data.
• Settings are exposed. You can change house systems, which points display, and aspect options — the kind of control free tools often hide or omit.
• It spans devices. A chart saved in the online dashboard is reachable from any device, which free single-page tools generally don't offer.
• It's a paid product with a free entry point. The free download and free birth chart let you test the interface and interpretation style before committing; the paid tiers unlock the fuller feature set.

Who should consider it

Choose TimePassages if you want interpretation text alongside the chart, you work with multiple people's charts and need them saved, or you want one tool that follows you from desktop to phone. Beginners get a low-friction start via the free chart; professionals get the Advanced Edition for actual client work.

Look elsewhere if you only need a one-off chart image, you don't want to pay for software, or you already have a workflow built around another platform and only need raw chart data.

Before you buy

Two low-risk steps: generate the free birth chart to judge whether Seltzer's interpretation style matches how you think, and take the free download to test the interface on your own machine. If both feel right, the desktop Standard edition at $79.00 is the entry purchase — and it's worth checking the site first, since Astrograph runs limited-time discounts (a 30% off Standard promotion has been advertised with a fixed end date).
