Ours: 1 - Sales managers are 1st level, software analysts. They clarify your needs. You get 3 results: what users can do - user stories, recommended technologies, and estimate based on previous projects. 2 - Analysts clarify details and draw wireframes. They are mockups of all the pages with clickable buttons. So you can play with your app before itโ€™s developed and make changes for cheap. Based on wireframes, we calculate project time and price estimation. 3 - Designers draw clickable graphic design prototypes. 4 - A team of developers, test engineers, and a project manager develops the product. 5 - The team installs it on your server and helps with app store submission. We do maintenance - part-time work on minor improvements after launch. Write to discuss and estimate your project. We give user stories and recommend technologies for free after a call. Without a call, we canโ€™t do it well, unfortunately. All the right questions in writing would have taken days and still much missed. Answer the same workday. On weekends we rest, but if you have a chance - respond too. So please write to us now :)
