Made for you, with a person.
Sit down with your coach. Your weight, your goal, how you eat, how you live. Together you pick one of six plans, a simple daily count of protein, vegetables, fruit, starch, dairy and fat.
Health coaching, with a real coach
Log your food with a tap. Order the labs you want. Build your supplements from a practitioner dispensary. A coach who sees what you see, when you want one. And Circa OVA, the cycle tracker only you can read, included.

The food
No prepackaged meals. No shakes. No counting calories. Your supermarket, your restaurants, the dinner you cook for your family, on a plan made for you with a real coach. It is the way weight loss has worked for decades, now on your phone.
Sit down with your coach. Your weight, your goal, how you eat, how you live. Together you pick one of six plans, a simple daily count of protein, vegetables, fruit, starch, dairy and fat.
Grocery food, restaurant food, the family dinner, all on the plan. Log what you ate with a tap. One dot per serving, and the day fills in as you go. Nothing to weigh, nothing to add up.
Step on the scale and see the week, the month, the quarter in one view. Your coach sees the same picture, and when the plan needs changing, you change it together.
Labs, direct
Hundreds of tests, from standard bloodwork to genetics, hormones and the gut, in one place. Order the ones you want through Grindstone. No referral, no insurance forms, no waiting room. You see the price before you commit.

Browse the full catalogue and add tests to your list, or start from what your coach suggests.
Your coach confirms the list and the order goes in. The price is on the screen before you commit, and we bill you.
Get your blood drawn at a collection site close to home.
Every marker lands in the app, shown the way the lab reported it, with the lab's own flags. You and your coach read the same page.
Go deeper than the basics
Supplements
Practitioner-grade supplements, in a dispensary built into your app. The formulas clinics stock, at the doses they use, without the guesswork of a store shelf.
Every brand in the dispensary is one practitioners order for their own patients. Precise doses, clean labels, and no filler for the sake of a longer list.
Start from your plan, your labs and your goals. Add what supports them and leave out what doesn't. Your coach can help you decide.
Order in the app. The dispensary ships it straight to you.
Supplements support nutrition. They do not replace food or treat anything, and medical questions belong with a qualified clinician.
Circa OVA · included
A period and cycle tracker for everyone with a cycle, built into Grindstone Elements. It learns your body, tells you how sure it is, and keeps everything you log where only you can read it.

Everything you log is encrypted on your phone with a key only you hold, and opens with your phone's own lock. No coach sees it. No ads or analytics run on these pages, and nothing is ever sold.
Your next period comes as a most likely day with a range around it, and how sure it is. When it can't know yet, it says so.
It starts from clinical guidelines and studies of more than 600,000 cycles, then learns yours. Every number in the model is labelled with its source.
For every stage. From a first period to perimenopause. On the pill, after a baby, while breastfeeding or coming off the pill, the ranges widen when life does.
Windows are estimates and not a method of contraception. Circa OVA is for information. It names patterns, never conditions, and does not replace a doctor's advice.
The difference
Someone who reads your week and talks it through with you. Not a chatbot. Not an algorithm deciding for you.
Six numbers a day, set once. No calorie tables, no barcodes, no maths at the table.
Labs and supplements come from practitioner-only suppliers. We say who, before you tap.
We do not sell your data. Circa OVA is encrypted on your phone, and we cannot read it even if asked.
For coaches
Your clients log their food, choose their labs and build their stacks in the app, and you see all of it as it happens. One console for every client.
Pick the plan with your client, confirm it, and it is on their phone. Change it later and the history keeps the old one where it belongs.
Dots, water, weigh-ins, how they felt. Seven days, a month, a quarter. What they log is what you see, the same day.
They choose the tests they want or start from your suggestion; you confirm the list. They build their stack; you weigh in when asked. The lab and the dispensary handle the rest behind the scenes.
Request-only
We are opening to a small group of clients and coaches first, so every one of them gets a real coach. Tell us which you are.
Real food. A real coach. One app.
Grindstone Elements supports coaching and education. It does not diagnose, treat or cure anything.
