Coinlytics allows you to define a balance of a particular asset: i.e. how much of a particular coin or token you hold.
Once you've done this, you can easily see your holdings for a coin/token in the app, and you can also switch between seeing pricing and your balance on any pricing widget:
How to define a balance and toggle view mode on a Widget.
Remember that you balance will be displayed in the currency that you choose in the widget. For example, if you want to see your holdings in Australian Dollars, edit your widget and choose Australian Dollar for the Currency setting.
You can also choose to hide your Portfolio data in the app - if you want to take screenshots or show the app to someone else, go to More -> Config and toggle 'Stealth Mode'. In Stealth Mode, all portfolio information will be hidden across the app and all Widgets.
