The app your glucometer
should have shipped with.

Most glucometer apps want an account and send your data to the cloud. Glucera syncs straight to Apple Health — on your device, privately. No account. No subscription.

Why Glucera

What you actually get.

See what your meter can't show you

Your meter shows a number. Glucera shows what it means — time in range, variability, estimated A1c, meal averages.

Works with what you already own

No new hardware, no proprietary dongle. If your meter has Bluetooth and pairs with an iPhone, it'll work.

Your data belongs to you

Your readings go from your meter to Apple Health and that's it. No server, no cloud, no account. Not to me, not to anyone.

Privacy

No data collected. Ever.

Glucera has no server. There's literally nowhere for your data to go even if I wanted it to.

Meter → iPhone → Apple Health. Full stop.

No account to get breached. No cloud to get leaked. There's no infrastructure to hack because there is no infrastructure.

Stored on your device only Everything lives in Apple Health. You control it, not me.
No account, no email, no sign-up Just open it and sync. Delete the app whenever you want — your readings stay in Health regardless.
No analytics, no crash reporters, no SDKs The app phones home to exactly nobody. No tracking code of any kind.
FAQ

Common questions.

  • Does it work with my glucometer?

    If your meter has Bluetooth and pairs with an iPhone, it'll almost certainly work. Glucera uses the standard Bluetooth glucose protocol, which covers most modern meters — FreeStyle, Contour, Accu-Chek, OneTouch, and others.

  • Is it really free?

    Genuinely free. No subscription, no in-app purchases, no ads. I don't collect your data so there's nothing to monetize. The whole app is available from day one.

  • What happens to my readings if I delete the app?

    Nothing. Your readings are stored in Apple Health, not in Glucera. Deleting the app has no effect on your data. Reinstall later and it reads your history back automatically.

  • How is this different from my meter's official app?

    Most manufacturer apps want you to create an account and upload everything to their servers. Glucera keeps it local — Apple Health only, nothing leaves your phone. You can run both side by side if you want.

  • What iPhone and iOS version do I need?

    Any iPhone running iOS 17 or later. Apple Watch complication requires watchOS 10+.
