The ProForta Challenge · twelve weeks · Android-first · 50 places

Keep your muscle through your GLP‑1 journey.

On a GLP‑1, some of the weight you lose is muscle. ProForta reads your phone’s Health Connect data, and a Dexcom Stelo if you have one, on your own private node, and turns it into a muscle preservation score with plain-language guidance. Your data stays yours.

The real problem

GLP‑1s work.
Sticking with them doesn’t.

Semaglutide and tirzepatide are transformative, but in early real-world cohorts many people stopped within a year. And a meaningful share of the weight lost is muscle, not fat, which accelerates the sarcopenia that shortens healthspan.

The drugs don’t fail people. The support system does. ProForta changes that with continuous, plain-language guidance from your own data, delivered by a personal agent that works only for you.

Connect your health data

On your Android phone, connect the data your device already collects through Google Health Connect, and a Dexcom Stelo if you have one. It flows in on your terms, revocable any time via LifeCare.ID®.

Your agent gets to work

Your personal agent runs on your own node, reading your weight trend, training, protein, recovery, and glucose context to deliver plain-language guidance. It scores from day one and tells you honestly how sure it is.

Keep your muscle

Your muscle preservation score reads protein, training, recovery, and glucose context, all driving the one outcome that matters: keeping muscle while the fat comes off. Levers with no data read as “no reading”, never a false zero.

Stay on track through titration

Log your dose and any side effects, and see them on a simple journey timeline. When it helps, ProForta pulls it into a visit-prep summary you can share with your provider, who stays the decision-maker on your medication.

Built for longevity

Everything you need to achieve your goals.

Ruthlessly focused on outcomes that extend your healthspan.

The muscle preservation score

The one metric that matters on GLP‑1 therapy: are you keeping muscle while the fat comes off. It reads protein, training, recovery, and glucose context, computed continuously on your own node. No corporate cloud ever sees your raw data.

Your private agent

Daily guidance from an agent that runs on your own node, not a corporate cloud. It reads your data there and shows you only the result, with a plain “why” behind every number.

A GLP-1 journey timeline

Log your dose and any side effects as you titrate, and see them on a simple timeline. Context and self-tracking, not dose or treatment advice.

Glucose context, if you have a CGM

Connect a Dexcom Stelo and your glucose steadiness becomes helpful context for the score, read via time-boxed LifeCare.ID® tokens and interpreted in plain language. It is optional, never required.

A visit-prep summary

When it helps, ProForta pulls your trend and your logs into a short summary you can share with your provider, so your next visit starts from real information.

The beta

A small, hands-on beta with a shared goal.

We are opening about 50 places for people on a GLP‑1 who will actually use it and tell us what is wrong with it. It is early and rough, and you get a direct line to the team building it.

The goal we are chasing together: prove that muscle can be kept during GLP‑1 weight loss. At the end, everyone in the cohort gets a shared report on how the group did.

Data you actually own

See who has your data.
Revoke access in one tap.

ProForta stores no health data. Your biometrics live at source and on your own node, which keeps only interpreted results. Every access is logged. Every permission is yours to grant or revoke instantly.

Built on LifeCare.ID®. It is an open permission layer that turns data rights from a legal concept into something you can monitor and control in real time.

ProForta runs no servers that store your health data. Ever.

How it works, under the hood

Your data never leaves your control.

From the moment you connect a source to the insight on your screen, here is exactly what happens, and what never does.

You grant access, scoped and revocable

Connect a source and you authorize it through LifeCare.ID®: a specific, time-boxed permission you can see and revoke at any time. Nothing is ever accessed without your explicit grant.

Your data travels encrypted to your own node

When a source has new readings, they are sent over an encrypted connection to your own node, your private corner of LifeCare.ID®, not to a corporate cloud that pools millions of people’s data.

Your agent does the work on your node

Your personal agent reads the raw data on your node and interprets it, turning glucose curves, recovery, and body composition into your Muscle Preservation Score and plain-language guidance. The intelligence runs next to your data, not on someone else’s servers.

Only the insights are kept; raw data is purged

Raw biometric values are processed in a short-lived working buffer and then purged. What persists is only the interpreted result: scores, trends, and guidance. ProForta keeps no durable copy of your raw health data, anywhere.

You see the results, and stay in control

The app shows you the interpreted output, never raw values, never anyone else’s data. You can see every source and agent that has access, and revoke any of them in one tap.

What never happens: your raw biometrics are never shown to the app, never stored durably, and never sent to a corporate cloud. You hold the keys. ProForta only ever works with the results.

Questions

Good to know

Do I need an Android phone?

For now, yes. The main data path uses Google Health Connect on Android, so the beta is Android-first. iPhone support is coming, and if you apply from an iPhone we will write to you when it is ready.

Do I need a continuous glucose monitor?

No. A CGM (a Dexcom Stelo) adds helpful glucose context, but it is not required. You get a muscle preservation score and daily guidance from your Health Connect data and what you log. Levers with no data read honestly as “no reading”, never a false zero.

What is LifeCare.ID®?

It is your health identity and the permission layer ProForta is built on. You sign in with it, and it lets you see every app that has access to your data and revoke any of it in one tap. Your device holds the key.

Where does my health data live?

On your own node, not a corporate cloud. Your raw biometrics are processed there and never stored durably. The app only ever shows you interpreted results. See how your data is handled.

What do you collect during the beta?

The site collects only what you send with your application: your email, your GLP‑1 status, and your platform. There are no third-party trackers or analytics. The app and your node handle your health data as described above. See our privacy policy.

Is this medical advice?

No. ProForta is a wellness and information tool, not a medical device. It does not diagnose or treat, and your clinician remains the decision-maker on your medication and dose.

What does the beta cost?

Nothing. It is a small, free, hands-on beta. We are looking for people who will use it and tell us what to fix, so expect rough edges and a direct line to the team.

How do I leave?

Any time. You can revoke every data grant in one tap through LifeCare.ID®, and ask us to delete your application and account data. Your data is yours to take back, by design. See our privacy policy for how to request deletion.

How do I get in?

ProForta is a small beta. Join here: your guardian asks a couple of short questions and tells you where you stand, straight away. No forms, no codes to type.
