Thanks for reaching out. The SoFi Money app is experiencing an issue that affects certain iPhone models which, depending on the model, may prevent you from transferring money or may limit you to transferring whole dollar amounts only.
You can use the SoFi.com mobile website to transfer funds as a workaround for this issue.
As a reminder, SoFi does not support 1st gen iPhone 4 / 5 / 5s / SE devices but we are working on a fix for this issue.
