Building Embera

Why I'm building a GLP-1 tracker with no account

In short

Embera has no account because health logs are personal, and the simplest way to protect them is to never hold them. Your logs stay on your iPhone and in your own private iCloud. The trade-offs are real: no Android, no web version, and no way for us to recover your data. We think they are worth it.

Most apps start with a sign-up screen. Embera starts with a few quick questions about your treatment, and no email field. That was one of the first decisions in the project, made before the design.

The reason: health data is personal

A GLP-1 log is not a to-do list. It holds your medication, doses, weight, side effects, sometimes your cycle and progress photos. If that sits on a company’s server tied to your email, you have to trust that company with it for as long as it exists, and whoever buys it next.

The simplest way to protect that data is to never hold it. So Embera has:

The app does send anonymous usage signals, like “onboarding step 5 reached”, so I can see where people get stuck. They never contain health data. That is written in the privacy policy.

The second reason: trust

While researching the category, one thing came up again and again in GLP-1 communities: people felt burned when an app they had logged in for months suddenly put features behind a paywall. Once your history is inside an app, leaving is hard, and that is exactly when a surprise hurts most.

So alongside “no account”, Embera makes two promises:

What it costs

No account is not free of trade-offs, and it is fair to be clear about them:

What it means for the app

Everything is calculated on your iPhone: your estimated medication level, your food noise patterns, the cycle view, your run-out date. No AI service, no cloud processing. The only outside lookup is a barcode scan in the nutrition log, which asks the free Open Food Facts database about the product you scanned.

If you have questions about any of this, write to me. I read every email.

Embera is a personal tracking app, not a medical service, and the people writing these guides are not clinicians. This article is general information, not medical advice. Always follow your prescriber's or pharmacist's instructions.

See your own week, not an average one.

Embera turns the shots and check-ins you log into your own patterns. Free to use, no account, your data stays on your iPhone.
