Overview
When you first start the loan analyzer it will present you with the following view.
This view shows a table of loans that have been created. Each entry in the table represents a separate loan that shows the name of the loan, loan amount, interest rate, amortization and payment amount.
The top navigation bar contains two buttons. The top right edit button allows you to switch the view into edit mode where you can delete a loan from the list. The top left button allows you to add a loan.
Creating a Loan
To create a loan tap on the top right add button 
in the navigation bar. The following view will be presented to you.
Notice when you create a loan a set of default values are created. Lets go ahead and change the loan amount by tapping the "Loan Amount" section as shown below.
When you tap the "Loan Amount" section a slider pops up. You can slide the slider right or left to change the value of the loan amount. Let's change the loan amount to $240,000.00 by first sliding the slider all the way to the right. When you slide the slider all the way to the right the maximum and minimum limits change. This allows us to change the the loan amount to the next highest increment value. Now lets slide the slider again to the right so that it's set to $240,000 as shown below. Notice how several difference indicators are shown. You can see how the loan amount that the principal, interest and payment amounts changes as you change the loan value. In addition, the pie chart changes to reflect those changes.
Lets say we want to use a number key pad to enter the amount instead of using the slider. We can click on the arrow icon 
to display the number key pad. Lets enter $240,244.00 using the keypad. We need to first press the backspace button to clear the last 5 digits and then enter 24400. Now click the "Loan Amount" header to close the key pad.
Next we will change the interest rate by taping the "Interest Rate" section. At this point a slider is present to allow you to change the interest rate value and the compound period. Lets change the interest rate to 3.75% by sliding the slider to the left.
Next we will change the amortization to 25 years and 6 months by first taping the "Amortization" section. Slide the top slider to the right to change the year value to 25 and the bottom slider to the right to change the slider to 6 months.
Let's change the payment frequency from monthly to bi-monthly. Tap on the "Payment Amount" section to bring up the key pad to change the payment amount. Select the "Bi-Weekly" button.
We can change the name of the loan by tapping the "Name" section and entering a new name for the loan. Furthermore, we can change the start date of the loan by clicking the "Start Date" section.
If you want to add a lump sum refer to the "Creating a Lump Sum" section in this manual.
Now we are ready to save our loan. Tap the "Save" button in the top left corner of the navigation bar. Notice when you click the save button the difference indicators disappear this is because the loan has been set to the new values and there are no difference. At anytime you can edit the various values to see how the principal and interest amount change. Once you make a change the reset button and save button appear in the navigation bar so that you can either reset the loan values back to the original values or save the new values.
Editing a Loan
From the overview view tap on the loan you want to edit. This will bring you to the loan details view. In this view you can tap on the various loan values to change the loan amount, interest rate, amortization, payment amount, loan name or start date of the loan. Lets edit the loan amount by tapping the "Loan Amount" section. This will bring up a slider that you can slide right or left to change the value of the loan amount. When you slide the slider all the way to the right the maximum and minimum limits change. This allows us to change the the loan amount to the next highest increment value. Similarly, you can slide the slider all the way to the left so that you can change the amount to the next lowest increment value.
Notice how several difference indicators are shown. You can see how the principal, interest and payment amounts changes as you change the loan value. In addition, the pie chart changes to reflect those changes. If for some reason you want to use a number key pad to enter the loan amount you can tap on the up arrow button to bring up the number key pad.
You can click on the other sections of the loan detail view to change the interest rate, amortization, payment amount, loan name and start date of the loan. Notice that when you change the value of one option it effects the values of the other options. For example, when you increase the payment amount both the interest rate and amortization values decreases. This is expected, since you are increasing the payment amount it takes less time to pay off the loan and you are paying more principal and less interest on the loan.
You can also add or edit lumps sums to the loan. Refer to the "Creating a Lump Sum" section and the "Editing a Lump Sum" section in this manual.
Deleting a Loan

in the top left corner. You can then tap on one of the delete icons located on the left of the view. Next top on the "Delete" button
