What's inside

four ways to read the day

Each tool is rooted in classical Chinese metaphysics & built for how you actually live now.

01 · Daily View

wake up & know today's energy

No generic horoscopes. No vague advice. Flow Tong Shu delivers the actual classical reading for today — pillar, element, what to pursue, what to defer — written in plain English you can act on before your first coffee gets cold.

pin events to the auspicious window in one tap

Monthly View — auspicious dates calendar

02 · Monthly View

see the whole month before you commit

A lunar-aware calendar that maps exactly which days favour which actions. Solar & lunar dates sit side by side, including all 24 solar terms. The 12 Day Officers are visible at a glance, so windows for travel, signing, opening, & moving are impossible to miss.

Finding the right day is half the work. The right hour seals it. Flow Tong Shu scores each window by heavenly stem, earthly branch, & star quality, then pushes your event straight to Google or Apple Calendar in one tap. Name it, set your start & end time, tag it as Auspicious, Personal Peak, or Day to Avoid, and it lands in your calendar with full almanac context attached.

things people ask

Short answers to what comes up most.

what is the Tong Shu, exactly?

The Tong Shu (通書) is the 2,500-year-old Chinese almanac — the system most Chinese families consult for choosing wedding dates, opening businesses, signing contracts, & starting anything that matters. Flow Tong Shu computes the same readings, instantly, in plain English.

do I need to know Chinese astrology?

Not at all. Every reading is written in plain English. Tap any term — pillar, branch, day officer — for a one-line explanation. The classical system does the work. You just read your day.

how does the 3-day free trial work?

Pick any paid plan & get full access for 3 days. No credit card required. If you don't continue, your account stays on the Free tier with the daily reading intact.

can I cancel anytime?

Yes. Two clicks from your account, anytime. Paid access stays active until the end of the billing period. No questions, no friction.

is my birth data private?

Always. Birth profiles are encrypted, never sold, never shared, never used for advertising. We follow the same data principles a temple would: what's yours stays yours.

what's the difference between the plans?

Free is for trying it out — today's daily reading, daily summary & a view-only natal chart, no signup commitment. Lite ($9/mo) opens the full month: monthly view, daily diary, hour-by-hour planner, personalised daily hexagram, save dates, 2 natal profiles & ±1 month of date lookups. Pro ($19/mo) is where most people land — it unlocks the Date Selector, Calendar sync, custom saved-date tags & multi-profile date matching, with 4 profiles & ±3 month range. Master ($39/mo) stretches your range to ±5 years & gives you 10 profiles, plus access to Personal guide when it ships. Business ($59/mo) is for planners, masters & teams: unlimited date range, 40 profiles & priority support.

does it work in any time zone?

Yes. Flow Tong Shu calculates pillars & day officers based on solar terms in your local time zone, so the reading is always correct for where you are.

pick the right day,
every time.
