The sky today

Every planet, in its orbital

Each one traces its own figure around us. Venus draws five petals, Jupiter eleven loops. Each card carries the gate and line that body is in right now.

For analysts and students

The most exhaustive Human Design analysis tool out there.

Every layer a chart carries, calculated and written out, from the gate down to the Base. Built for the people who study this and work with it. The Web, the analyst workspace and the API come next, in 2027.

Casting has its own tab in the app. Write your question, hold to throw, and build the six lines yourself. Every gua is also a gate, so the answer lands in your own mechanics.

Warm-up · 3 of 7

Do you want to eat something right now?

Tap one. Do not think about it.

The experiment

A question. A response. Your own record.

Knowing you are a Generator does not stop you from initiating. Practising your response does. Each session puts one binary question to your body and waits, then builds a record of what your yes led to.

Sacral response is for Generators and Manifesting Generators. Every other Type gets the chart and every layer of mechanics.

The library

Written, not tabulated.

The mechanics can be calculated. What they mean has to be written, so every one of these was written by hand, grounded in the system and in our own words.

Gate and lineGate 25.3, with its Colour, Tone and Base and what it means, written out.
The MandalaThe same placements on the wheel of the 64 gates, around your bodygraph.
Fixed starsThe star a placement sits on, and how far from its exact position.

Pages from a report made for an invented chart. The library in the app carries the same writing.

64

Gates

Every gate with its hexagram, centre, circuit and place on the wheel.

384

Lines

Each line of each gate, with its planetary fixings: where it is exalted and where it is in detriment.

Reference

The hexagram texts alongside the mechanics, so both sit in the same place.

Reports

A chart you can hold.

Every report is made from your own chart by Orrery, the same engine as the app, and written out in full. Choose dark pages or parchment. It arrives as a PDF to save, print or share, usually within a few minutes.

Ten pages from a sample Full Self Report. Tap a page to enlarge.

Arginine

The 64 Codons

Every gate is also a codon.

Three bases of the genetic code. The 64 are set out by amino acid family, each with its triplets, its gates on the bodygraph and what that chemistry does in a chart.

Composite

Two charts, read as one.

Put anyone's chart over yours, you in cream and them in blue. See the channels you complete together, where one of you defines what stays open in the other, whether a split closes, and what the sky held on the day you met.

Fixed stars · The 2027 chart

15 February 2027.
The Keys change.

Eight gates in the G centre hold still, as locks. The sky turns beneath them with the precession, about one gate every 412 years, and the gate each lock brings into line is its Key. For the first time in about 412 years, the eight of them change together, and the bodygraph in the middle lights differently.

Power, intuition, intimacy, beginnings, presence, shock, spirit and ambition turn the background towards individual mutation. This era also frames the emergence of Raves.

Questions

Asked before joining.Asked before downloading.

Gold trees over blue water, the Classic I Ching painting for Gate 61
Classic I Ching61, Inner Truth
How is this different from other Human Design apps?

Most show you your Type, Strategy and Authority and stop there. Sacral Compass calculates the same chart, then adds a daily experiment, a written library and a record of your own responses.

I am not a Generator. Is it for me?

Yes. Every Type gets the full chart, Variables, Story Line, transits, gates, channels, connections and notes. Only the Sacral response practice needs a defined Sacral.

How accurate is the calculation?

It runs on Orrery, our own ephemeris engine, built from NASA/JPL data and fitted to 0.003 arcseconds against JPL. Reference charts are pinned in tests, down to Colour, Tone and Base.

Does it replace working with an analyst?

No. The app explains the mechanics in your chart. A trained analyst going through your whole chart with you, in conversation, is a different thing and you may still want one.

What is in a report?

Two editions, both made from your own chart. The Self Report is about 220 pages and covers your core mechanics. The Full Self Report is about 400 pages and adds the Story Line, Linkage, Dream Mechanics, Cartography, the Nine Rooms, Codons and Fixed Stars. Pick dark pages or parchment when you order.

Is it on Android?

Not yet. It is an iPhone app first. Android, a web version and an API are planned for 2027.

What happens to my birth details?

Your chart is calculated on your phone. Features worked out on our server, such as returns, cycles and connections, use the birth moment for that one request and discard it. You can delete your account from inside the app, and the privacy policy sets out exactly what is stored. A report is made on our server from the name and birth details sent with the order, and those are deleted once the report is in your hands.

What does it cost?

The subscription is $14.99 a month or $119.99 a year, which comes to about US$10 a month. Both start with a 3-day free trial, and you can cancel any time before it ends. Payment and cancellation run through the App Store.

What does the subscription include?

The whole app: your chart and every layer under it, live transits and cycles, the Sacral experiment for Generators and Manifesting Generators, the library of gates and lines, connections and the Penta, widgets and notifications. Subscribers also have a Full Self Report included on subscribing, then reports each month, and pay less for any more.

Do I need a subscription to buy a report?

No. The Self Report is $19.99 and the Full Self Report is $29.99, and anyone can buy one in the app. Subscribers have one Full Self Report on subscribing, then two Self Reports and one Full Self Report included each month from day 14, and pay less for more. A free trial does not include reports.

Will there be a web version or an API?

Both are coming in 2027, and the waitlist is for them. The web version puts your account and chart in a browser. The API offers our chart calculation to other tools, so coaches, analysts and other apps can use it. Android is planned too.
