About this app

Heartwood is a private, open-source window into the health and fitness data stored in Android's Health Connect. It only ever reads, nothing you see leaves your device, and there are no accounts, ads, or trackers.

Features:

* Today dashboard, Material You cards for steps, heart rate, sleep, energy, distance, exercise, SpO2, weight, blood pressure and more, each with an at-a-glance sparkline. * Detail views, tap any metric for a full chart, statistics and recent records. * Weekly summary, daily averages measured against goals you set, with progress rings and week-over-week trends. * Home-screen widgets, your key numbers, themed to match your wallpaper. * Export, save your accessible data to a CSV or JSON file at any time.

Heartwood reads data through Health Connect, so it works alongside whatever apps and wearables already write there. You stay in control of exactly which data types it can read, and can change or revoke access at any time from Health Connect.

1

Open Settings on your Android device

2

3

Enable "Allow from this source" for your browser or file manager

4

Open the downloaded APK file from your Downloads folder

5

Tap "Install" and wait for installation to complete

6

Launch the app from your home screen

Make sure to re-enable Unknown Sources restrictions after installation for security.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be dev.easonhuang.heartwood is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

No earlier build is on record for Heartwood, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Heartwood, and a listing is removed when the evidence for it stops holding up.
