The igMember app has the following features:
intelligentgolf make a nominal charge of £1.99 per year to use all the features of the app, but you can download and try the app for a month at no cost.
If you don't feel that the app is worth that amount, then you can cancel at any time in the first month for no charge. Of course access to the normal club information via intelligentgolf is still totally free via a smartphone when using a browser.
It is available in the App Store and the Google Play Store. For full instructions, go to here or go to My Golf -> Preferences and look for the link to the app. You can find much more information there.
