The Home Tab
The home tab provides a snapshot of what is due or coming due in the next few pay cycles.
There is also a graph at the bottom that can be viewed by calendar month or by pay cycle by toggling the mode using the blue buttons.
The Summary Cards
The top section will show a overdue card alerting you to a missed payment if one exists. Otherwise it is not shown. 
The first summary card shows what payments are due before your next pay comes. This will include any overdue amounts. 
The following cards show the amount from each pay to the next pay, giving information for the next three pay cycles.
Pressing on any card takes you to the Payments list tab.
The Chart
The chart shows the totals for 4 months, and can also be toggled to show 4 pay cycles instead by pressing on the blue buttons.
