The Conceivable system explained
Most fertility products are point solutions: an app that tracks, a ring that measures, a bottle that hopes. Conceivable is the only system that combines all three under one clinical approach, which is worth explaining plainly because "integrated" is easy to claim and rare to build. The front door is the app, and the app is free.
The system starts with a free download
Conceivable Periods covers six chapters of life in one iPhone app, from first period to menopause. Kai, an AI coach built from 25 years of clinical practice and more than 10,000 cases, reads your data and gives you one clear daily plan. Try everything free for seven days; basic tracking is always free.

The three parts
| Part | What it does | Why it is in the system |
|---|---|---|
| The app (start here, free) | Tracks cycle, BBT, sleep, stress, food, and symptoms; computes the Conceivable Score across five pillars; delivers one clear daily plan; Kai (an AI coach built on Kirsten's 25-year practice, clearly identified as AI) answers questions anytime; reads uploads of labs and wearable dashboards | Fertility is daily work; the app is where the work happens |
| The Halo Smart Ring ($250, optional) | Passive temperature, sleep, recovery, stress, and movement capture overnight; ring data tracking in the app is free forever, no ring subscription | The best data is data you never have to remember to collect |
| The personalized supplement pack (optional) | Personalized supplements built from a free assessment, itemized with doses and reasons | Targeted nutritional support for the patterns your answers surfaced; Kai suggests it only when your signals point somewhere specific |
Why integration matters
A tracker without a plan produces anxiety with charts. A ring without interpretation produces graphs. Supplements without personalization produce expensive optimism. Connected, each part improves the others: the ring feeds the score, the score shapes the plan, the plan explains the pack, and Kai holds it all together in one conversation. That loop is what I ran manually in clinic for 25 years across more than 10,000 women; the system is that loop, automated.
Who it is for, honestly
Someone happy passively tracking does not need this, and the free tier of the app, or a free tracker, will serve her well. The system is for the woman actively working on her cycle health who wants to stop guessing and start executing one clear plan every day. For people who want the whole system with accountability on both sides, there is also the Conceivable Promise, a membership with a money back guarantee.
Quick answers
What does it cost to start?
Nothing. The app download is free, basic tracking is always free, and full coaching is free for seven days, then $14.99 a month or $99 a year.
Do the parts work separately?
The app works fully on its own. The ring and supplements each add to the app but are never required.
Is this medical care?
No. Conceivable is a wellness system that complements, and never replaces, your medical team.
