The ANT USB Service is a free Android application developed by ANT that enables ANT wireless communication over a supported* ANT USB stick connected to your phone in conjunction with the ANT Radio Service. With this application, you can connect with millions of ANT+ devices, including some of the most popular sport, fitness, and personal health applications such as heart rate straps, running foot pods, cycling power meters, weight scales, blood pressure monitors, and more.

The application is compatible with most Android devices that have USB Host support, and all you need is a USB OTG cable and an ANT USB Stick. However, some devices may suspend the USB when the screen turns off, which will kill any ANT connections. This is a hardware limitation, and individual apps must add a workaround. Additionally, some apps using old versions of the ANT interface may not support ANT devices attached via this USB Service. In this case, you must encourage the developers of that application to update their app to use a more recent version.
