Part of our complete GPS ecosystem, the Lezyne Ally app is the key link between your phone and your Lezyne GPS device. The free app features the latest interactive and real-time technologies designed to enhance your cycling experience. Once paired to one of our GPS devices, you'll enjoy easy device customization, wireless ride syncing, route loading and mapping, and so much more. Experience effortless navigation, import .tcx and .gpx files, and connect cycling routes directly through the application. Additionally, the app is an easy-to-use resource to instantly save, store, and review rides from the palm of your hand. Activities can then be auto-synced to third party apps such as Strava, Komoot, Relive, TrainingPeaks, and more, as well as shared to popular social media outlets like Facebook and Twitter. With the Lezyne Ally app, you can also take advantage of our Lezyne Track feature. When enabled, simply create a list of email addresses in the app and those recipients will then be notified every time you start a ride. These notification emails will include a link to our live tracking website where coaches, friends, and loved ones can keep track of where you are and see all of your ride metrics. This app is for use with Lezyne Y10 and newer GPS Devices (2017 Model Year and newer). Please use the Ally V1 app with Y9 GPS devices (With a silver bezel). Lezyne -- Engineered Design
