The early class costs her nothing.

A month of 6:00 alarms, and her sleep and recovery look the same as before. She keeps the 7:00.

Looks calm. Her heart disagrees.

Her Apple Watch shows the last ten minutes of class are the hardest of her week. She stopped calling Pilates her easy day.

Two missed Mondays.

Her Long Line bookings show every class she kept. The only two she missed came after Sunday deadlines, so Monday is now her rest day.

Chloe's life, the reason for the work

Saturday in the park: no reformer, no alarm.

Her month, asked in ChatGPT.

At brunch Chloe asks ChatGPT how her month went. It answers from her classes and her nights, including the two short ones before deadlines.

The salad got eggs.

A month of desk-salad photos shows protein running short, not calories. Two eggs go in.

Regulars who save her a spot.

When she ran late on Thursday, a Long Line regular held her reformer.

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.
