OpenVitals

OpenVitals is a private Android dashboard for Health Connect. It helps you review activity, sleep, heart, body, hydration, nutrition, mindfulness, vitals, and optional cycle data in one local app.

Your health data stays on your device. OpenVitals has no account, no cloud sync, no ads, no analytics SDKs, and no app-level internet permission. The dashboard reads from Health Connect only after you grant permissions. Manual entries are written back to Health Connect only when you explicitly save them.

What you can do

Why OpenVitals

* Private by design: no account, no cloud sync, no ads, no analytics
* Dashboard focused: the home screen is read-only unless you choose to add an entry
* Health Connect as source of truth: OpenVitals does not keep a separate health record database
* Permission-aware: use one-tap setup or grant clear data categories individually, then change permissions later
* Open source: code, release notes, and builds are available for review

Requirements

OpenVitals requires Health Connect. On Android 14 and newer, Health Connect is part of Android. On Android 13 and older, install the Health Connect app separately.

It does not diagnose, treat, cure, or prevent any disease or medical condition. Always consult a qualified healthcare professional for medical advice, diagnosis, or treatment.

Is OpenVitals free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does OpenVitals require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is OpenVitals safe to install?
We link to the exact APK published by Manuel. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update OpenVitals?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded tech.mmarca.openvitals.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «OpenVitals» by Manuel and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
