## Description

Understand your current situation before deciding on your next step.<br><br>Tianyi uses traditional Bazi (Four Pillars of Destiny) charts as a foundation, combining the daily fortune telling with the specific problems you are facing to provide actionable advice, rather than vague pronouncements of good or bad fortune.<br><br>【How it works】<br><br>I. Enter Birth Information<br>Birth date is required; time and place of birth are optional. Entering the time will perform true solar time correction, making the chart more realistic; it can still be used without entering, but the judgment at the time-based level will be slightly coarser.<br><br>II. Ask Real Questions<br>Should I change jobs? Is this relationship worth continuing? Should I touch this money? Tianyi will analyze your Bazi chart, the daily fortune telling, and your questions together, rather than applying generic statements.<br><br>III. Leave a Mark, Review Changes<br>Record your mood and plans for the day, and review the aggregated view after a week or a month. You will see at what pace you are in better condition—this is determined by your records, not by the Bazi chart.<br><br>【A Few Words of Truth】<br>· Bazi is not a predictive tool. Tianyi provides perspectives and timing suggestions, but does not guarantee results. For decisions involving health, law, or significant finances, please consult the appropriate professionals.<br><br>* You can delete your records. All &quot;Remembering You&quot; entries extracted by Tianyi from conversations are visible and can be deleted individually. Low-confidence records will be marked as pending confirmation and will not proceed to subsequent conversations.<br><br>* No registration is required. Anonymous use is enabled by default; account binding is only required if you want to continue using a different device or keep your subscription linked to your account.<br><br>【About Subscriptions】<br><br>Tianyi Membership: Automatically renewing monthly subscription, US$6.99/month (currency varies by region). Includes unlimited conversations and the full version of &quot;Annual Fortune Analysis&quot;.<br><br>Two one-time purchases are also available: the full version of &quot;Annual Fortune Analysis&quot; and &quot;One Thing, One Calculation,&quot; which are valid indefinitely after purchase and will not automatically renew.<br><br>Subscriptions can be managed or canceled at any time in the subscription settings on Google Play. Cancellation takes effect after the current period ends.<br><br>Privacy Policy: https://tianyi.aicofi.com/privacy Terms of Service: https://tianyi.aicofi.com/terms
