Start with a conversation. Set up her profile with her knowledge and consent. Her own words are your best guide; Sangtinel helps you put that understanding into practice.

Who it's for

A look inside

Clear, calm, and easy to check daily

Every profile, her current phase, at a glance.

Cycle context, upcoming windows and calendar export in the planner.

Illustrative app views with sample data, showing sections from the same screen. Some sections require Pro. Cycle dates and planning windows are estimates.

What makes it different

Daily guidance that's actually about her

One practical action, shaped by current requests, optional context and past feedback. Guidance works offline; no daily logging is required.

  • Requests and boundariesCurrent requests and hidden actions constrain suggestions. An impression is not treated as something she said or entered herself.
  • Optional everyday contextRecord whether you are together or apart, how much time you have, or whether dinner is already handled. Entries can last today, three or seven days; direct requests and dinner plans apply today only.
  • Feedback that stays on your phoneMark Helped, Didn’t help or Didn’t try. Optional reasons distinguish timing, poor fit and doing something different. Review or remove feedback from the last seven days. Untried or substituted actions do not count as failures.
  • Authored guidance, not AI-generated text24 authored actions, with matching Say and Avoid examples. Wording adapts to partners and daughters, including child, teen and adult-daughter contexts. Free-text notes remain reminders, not instructions interpreted by AI.
  • Your choices stay in controlSuggestions explain their basis and flag limited context. You can hide an action, restore it later, or edit its wording. Editing words alone does not retrain selection. If nothing fits your limits, the app says so.

Cycle timing: a guide for planning

Estimated cycle dates can help you plan ahead. They do not tell you how she feels or what support she needs today. Her current words and wishes remain your best guide.

An optional extra: astrology

If astrology interests you, you can add a reflective perspective to the guidance. It is entirely optional and never takes priority over her requests or boundaries.
