Bad night, no leading.

After a bad night, Lucía runs in the middle of the pack and someone else sets the pace.

The song that pushed her hardest.

After each run she sees which Spotify song lifted her heart rate the most. This week it was the same one, twice.

Diabetes runs in her family.

Her mom has type 2 diabetes, so Lucía checks her A1c every year, drawn at home before work. Still normal, and her doctor credits the running.

Sunday's playlist, picked at breakfast.

The club argues over the long-run playlist. The winner plays from Spotify, inside Betterness.

Carbs that climb with the miles.

In her biggest weeks, her lunch photos show more rice. The one week they didn't, Saturday's pace fell apart.

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.
