iPMT is currently on hold in development. I've removed it from the app store in order to completely re-work it from the ground up and hopefully release the best version yet. I'm sorry for the inconvenience. I thank all of you for your loyal support and hope to bring a new and better version for you in 2016.
If you still have the old verison of iPMT there is a a workaround for FHA:
Step 1. Choose the Conventional option.
Step 2. Touch the "Option" button.
Step 3. Turn the "Custom Mortgage Insurance" option.
Step 4. Enter the appropriate MI factors.
