+# HRM
+
+An example heart rate monitor app for Android and MacOS using [git.wow.st/gmp/ble](https://git.wow.st/gmp/ble) and [Gio](https://gioui.org).
+
+The MacOS implementation uses a Core Bluetooth binding created by
+[NSWrap](https://git.wow.st/gmp/nswrap). On Android, Martijn van Welie's
+Blessed library is used to simplify access to the Bluetooth Low-Energy
+hardware. If you need to re-compile the Blessed library for any reason, you
+can use `go generate` from the `depjars` directory. To do that, you will need
+to have `gradle`, an Android SDK, and who knows what else installed on your
+machine.
+
+## MacOS:
+
+```
+git clone https://git.wow.st/gmp/hrm
+cd hrm/hrm
+go build
+./hrm
+```
+
+## Android:
+
+The `gogio` command from `gioui.org/cmd/gogio` must be installed to build
+an Android APK.
+
+```
+git clone https://git.wow.st/gmp/hrm
+cd hrm/hrm
+gogio -target android .
+adb install -r hrm.apk
+```
