The first step is to navigate to 'Future' in the menu bar at the bottom of your app and create a pocket or select an existing one. Then click on 'Create savings plan' and choose between the two savings options Pickpocket or Regularly. For each option you set the amount, for regular savings you also decide on the frequency (weekly or monthly). Finally, you have the option to set a goal if you want to. 

To edit your savings plan or goal, navigate back to 'Future' and select the desired pocket. To edit the savings plan, click on the left side of the dark field under 'Save automatically', to edit the goal, select the right side. You can choose a new savings option, change the weekly or monthly amount and adjust your savings goal at any time.

You can also delete the entire savings plan (via the three dots) or the goal at any time in the same place.
