Fax services can be improved, but overall a great investment

We don't have a fax machine or a business phone, and this app is the solution. This app allows me to use my cellphone (Different number) to send and receive calls and text. I also get to digitalize my fax. I just scan or better yet, save the document I want to fax without having to ever print it. Likewise, I receive my fax digitally and it's up to me if I want to print it. Also, since there is an app, I don't have to use my phone, I can use my laptop, tablet, or even alternate. I would love to see improvement in the product when it comes to faxing such as more categories, so I don't have to go in and individually click on EVERY FAX to know if it was successfully sent, or if it it's incoming or outgoing fax.
