You can easily do that within the app.
First tap on the Totals tab on the bottom.
This will bring you to the Totals Page. This shows your data in charts across different timeframes.
Along the Top tap the Pay button.
This will open another page where you can select your pay period.
Last 2 Weeks (this is also bi-weely)
Semi Monthly (1-15 and 16-end of month)
Tap the save button to select the timeframe and go back to the Totals charts.
If you've selected Last 2 Weeks each time you move back or forward by tapping the left or right arrows on each side of the dates, the timeframe will move by one week. This is because the app doesn't keep track of your pay cycle.
All of the fields needed to verify your paycheck are now totaled by your pay period. The totals are the row of fields on top of each chart. The one highlighted in blue is currently selected and displayed in the chart. This row is scrollable if there are too many to show all at once. To see the others scroll the fields to the left.
If you have another pay period not provided in the Pay timeframe you can also use the custom timeframe and choose any dates you need.
