What happens when you build an astrology app that does not use astrology jargon by default? Soulwise tried 14 chips, 160-character responses, and a jargon-mode toggle.

Most astrology apps assume you already speak the language. They open with degrees, houses, aspects, retrogrades. If you do not already know what "Saturn in the 7th opposing your natal Venus" means, the app has lost you in the first thirty seconds.

Soulwise started with a different question: what does an astrology app look like if jargon is the opt-in?
This is a short story about three design decisions, why we made them, and what they changed.
The daily check-in is one screen. It asks: what is going on today? Most apps answer this with either a mood slider, a free-text journal, or a giant experiences picker. None of those scale to twenty seconds.
We tried three taxonomies: A (8 chips), B (14 chips, 8 visible with a "Show 6 more" expand), and C (20 chips). B won. Eight visible chips reduce cognitive load; the six hidden chips catch the long tail without forcing scroll. The chips are situations ("conflict," "decision," "stuck"), not moods. Situations are easier to log accurately than feelings.
Multi-select is allowed with a soft cap at three. The fourth tap quietly nudges you to pick the most relevant. People are not as one-thing-at-a-time as mood sliders pretend.
The daily response card is capped at 160 characters. That is roughly two short sentences. The cap is not arbitrary.
Long responses are skipped. We watched users scroll past 300-word horoscope blurbs without reading them. The information cost dropped to zero because the reader gave up.
160 characters forces compression. The writer has to pick one thing that actually applies. The reader can scan it in three seconds. The response feels like a friend leaving a sticky note, not a guru pronouncing a verdict.
A bonus: at 160 characters, the response card fits in a notification preview. (It is not used that way in Soulwise, because we never put astrology or cycle content in push bodies; but the constraint forced good writing.)
Plain English is the default, but the technical layer is not destroyed. A "Show details" toggle expands the card to show:
Users who already speak astrology can pull the curtain back without leaving the app. Users who do not can ignore it forever. The same data drives the response either way.
Some examples of plain-English transit descriptions Soulwise uses in production:
None of these are astrological pronouncements. They are observations someone might make if they happened to know what your day looked like.
A note on tone, because it is a real risk in this space.
Soulwise is not Co-Star. The deadpan provocation ("you're delusional," "the universe is open") is funny once and fatiguing always. The voice rule is warm, grounded, and curious-not-prescriptive; the brand can observe, not pronounce.
It is also not a horoscope app reading the same forecast to a million people. The 160-character response is generated per check-in, conditioned on your situation, mood, cycle phase, active transits, and personal blueprint. The same astrology produces different cards.
Hiding jargon costs the app one specific kind of user: the astrology enthusiast who wants depth on the home screen. For them, jargon mode is a single toggle. For everyone else, plain English is the door.
If you want to try the picker, the Soulwise hub page has the interactive 14-chip demo. Pick three, watch how the response card responds.
The shorter version: jargon is a recruitment problem disguised as an UX choice. Astrology gets a wider audience when the default door is a sentence anyone can read.
Most users searching for an astrology app are curious, not initiated. Throwing degrees, signs, houses, and aspects at them in the first thirty seconds is a recruitment failure. Jargon mode is opt-in, not opt-out.
The technical layer underneath each daily card: which transits Soulwise weighted, which houses they activated, and what aspects shaped the response. Users who already speak astrology can pull the curtain back.
Co-Star leans into terse, sometimes provocative phrasing. CHANI uses ritual language and a softer cadence. Soulwise prioritises accessibility: warm, grounded, curious-not-prescriptive, plain English by default, with the option to switch into technical depth.
No. The same data drives the response. Only the surface phrasing changes. "Mercury retrograde is annoying" is the same fact as "Mercury is retrograde in your third house." The first one is more honest about how it actually feels.
