Invite-only alpha · iOS + Apple Watch · Cohort 1 forming

Stop collecting health data you never use.

You already have the data. Core turns it into direction. Food, training, fasting, sleep, and Apple Watch in one app, with a single next step on the home screen - backed by AxoAI, a multi-model AI system that checks itself before it tells you anything.

Apple Watch · iPhone alpha · No data sold, ever · You decide what a coach sees.

The Core promise

You do not need more rings. You need to know why the rings moved.

Core is built for the moment after the dashboard. The part where you have to decide whether to eat, train, rest, hydrate, keep fasting, change the plan, or stop pretending the week is fine.

See how AxoAI helps
01

The app earns tomorrow.

If Core does not make the next move clearer, it did not do its job. That is the bar for the alpha.

Apply for Cohort 1
02

No performance theater.

Missed meals, rough sleep, travel, skipped lifts, and imperfect logs count because they are the pattern.

Start with 14 days
03

Your record stays useful.

Use it for yourself first. Share a report with a coach or professional only when it helps.

How sharing works

A morning with Core

Five seconds to know what today is for.

Open the app. Yesterday's gaps, today's targets, and one thing to do first. Your watch caught the recovery dip. Dinner missed protein. The lift still works, but the plan changes before the whole day drifts.

Today's call

Do water first, keep calories steady, and make dinner boring enough to repeat.

The AI inside Core

Meet AxoAI.

Most fitness apps wrap a chat box around one model and call it a coach. AxoAI is built differently: load the real record, run the question through multiple model perspectives, let each pass check the last, then give you a brief you can actually use.

Tap Axo anywhere in Core. He already knows the fast, the lift, the sleep, the meal pattern, and the goal you are trying not to forget.

How AxoAI works
Axo pointing toward the AxoAI explanation Tap Axo Question · full record · three model perspectives · one final Axo brief.
01

Loads the real record

Food, fasts, training, sleep, Watch signals, labs, photos, and goals become the context.

02

Runs the check

Each model pass reviews the work before the final answer gets written for the user.

03

Acts like a guide

Brief, direct, fasting-aware, and focused on the next useful move instead of another wall of text.

Why this matters

Tracking is solved. Meaning is still missing.

Fitness apps can help, but only when people keep using them. The research keeps pointing to the same hinge: make self-monitoring easy, make feedback feel personal, and keep the app useful after the first burst of motivation fades.1,2,3

Reality

Nearly one-third of adults are not active enough.

WHO reported that 31% of adults and 80% of adolescents do not meet recommended physical activity levels.WHO

The problem is massive.
Engagement

The app only helps if you keep opening it.

The 2025 study Scott flagged found self-monitoring was the most common reason people used fitness apps, cited by 79% of respondents.3

Core has to earn the repeat.
Signal

Your own history beats another scoreboard.

Core starts with what happened in your week before badges, leaderboards, or social pressure. The point is progress you can understand.

No performance theater required.

Start here

Give Core two honest weeks.

Two weeks is enough to see the pattern, short enough to actually finish. Log food, fasting, hydration, training, sleep, body metrics, and wearable signals, then see what your routine actually looks like.

Private alpha · invite required

Cohort 1 is forming. Most applicants will not get in.

Core is not ready for everyone. That is the point. The first cohort stays small so we can learn from people who log honestly, notice what breaks, and tell us what would make them come back after motivation gets boring.
