I need an iPhone/iPad app. I would like it designed and built. I have already a calculation template on excel, and now I want to create a mobile application. So I need experts to develop a tax application. Is more like a platform for clients (the taxpayer) and for the operational person. for example, usually I was working with three apps of Microsoft: Excel, OfficeLens, and OneDrive. So what we need is a software to make the analysis, another to take the information of the picture, and one more to save the information in the cloud.
