I would not trust this app for tax returns. When using this app for my tax return the number seemed a bit off. I used TurboTax and got a very different, much higher amount. I then used H&R Block and got the same amount as TurboTax. I'm not sure why this is not working correctly but I would not trust it to get your maximum refund, go elsewhere. I don't know why they decided to use their own app when CreditKarma had there own that was much better.
