I was very excited about this app. After downloading and tried to scan my e-reciept, it didn't work. I kept trying but couldn't do it. Then I went through about all descriptions and realized, from Android, only Gmail works, and I'm not a Gmail user. If it's okay to use other emails for ios why not from Android? It's very disappointing. It's useless. I'm not going to open a new email account for this app !!
