Fasting before tomorrow's draw.

Tomorrow's draw is at 6:30, so dinner on the dock ends by 8:00. The reminder came yesterday.

Why his HRV dipped.

Arjun asks Bett-i about a low week. The answer comes from his calendar: three late dinners, three low nights.

Keeping his cholesterol in check.

At 28 his LDL came back high, and his dad had a heart attack at 52. He retests every three months, drawn at his kitchen table. The last two results are lower.

Arjun's life, the reason for the work

The deck after Sunday's sauna. Nobody checks a number.

Twelve Sundays. Same six people.

Sauna, cold tub, the walk to the beach. Sunday is his best night of sleep, every week.

Lunch on the dock.

One photo of the salmon bowl and it is logged. Tuesday, sled day, carries the most protein of his week.

The beach, not the blood work.

The crew walks down to Crandon Park after the sauna. Arjun posts the beach, never his cholesterol.

One heavy day, his doctor's order.

Dr. Lena asked for one heavy day a week. His Tuesday sled with Tom shows he keeps it.

A sauna pass at the desk.

Station Eight gave him a Sunday sauna pass for joining. Twelve Sundays later, it is the hour he never moves.

Dr. Lena reads the line.

Before each visit, Dr. Lena at Meridian Longevity sees a year of his labs and sleep. The visit goes to what to change.

How we built it

We filled in the gaps.

We looked at what you already get from other apps and filled in what was missing. We connected it so you stay in control, it stays simple, and it links to your real world. We care about every minute in the app, down to the smallest step.

Questions, answered.

Which devices work with it?

Record from your phone or the Betterness app for Apple Watch. You can also connect Apple Health, Health Connect, Garmin, Oura, Withings, Eight Sleep, Peloton and Wahoo. Running, strength, padel, yoga and dozens more are supported.

How do lab tests work?

Order labs in Betterness anywhere in the US through Quest Diagnostics, and BioReference where available. Go to a lab location or have a phlebotomist come to your home. You can also upload lab reports you already have. Each result is explained in plain words and followed over time, next to your training and meals.

Can my coach, gym or clinic join?

Yes, and it costs them nothing. Send them a link from the Team tab. They get their own Space on Betterness One, with you already in it. You choose which categories they see: activities, sleep, nutrition, labs or goals.

Who can see my data?

Nothing is shared with a business, coach or clinician until you choose, and they see only the categories you switch on. You can change access, export your data or delete your account at any time.

Is Betterness medical advice?

No. Betterness gives educational wellness information. It does not diagnose, treat or replace advice from a qualified healthcare professional.
