As a first time tech entrepreneur, I was confused if I should select one tool for mobile prototyping and other tools for implementation. I wanted to deliver my mobile app service as soon possible but I don't want to make mistakes when selecting tools. I have seen tools like Appcelerator, https://codiqa.com/ and PhoneGapp. Other than that should I also develop for android and iPhone separately, or should I use one of the above tools to develop once and deploy in different devices? Time and money is also a constraint for my startup. Please advice me. Thanks.
We help our customers design and build apps - traditional and mobile. One of my personal favorite tools for prototyping is a notebook and pen, followed closely by a good big whiteboard. Its not "sexy" or "modern", but there's something about the act of actually drawing designs out with your hands that can really bring a new element to the design process.
As for the tool selection, without knowing what sort of app you're considering any recommendation would be premature. Feel free to give me a call, or post some follow-up information (could be vague - is it an action game or a contact management solution for example).
