About

EMail Tracker

Read full description

This App is for sending position updates to tracking websites via EMail. For example when you've temporarily suspended your Iridium Go service, but would still like to log your location to your Predict Wind tracking page. It supports a number of formats and websites and allows for custom destinations and formats to be defined. Note: if you have an active Iridium Go service, then Predict Wind disables updates to your tracker via email. Note: on iOS you must install and configure the Apple EMail App with an account.
