Hello,
We are a software development company based in India and we mainly work on custom requirement. We have developed mobile apps in various fields and our latest one was in auto industry which is still in process. So, please contact us for examples of our work. We assure you that we can develop the type of app you are looking for within time and about the budget, it may or may not vary after getting the full requirement.
Now, we would like to summarize our understanding about the type of app you are looking for. We have gone through the example app you mentioned below in the description and it seems like you are looking for a simple app which will have mainly four key features i.e. My Profile, Call, Email and Chat. Instead of patients, here you want to have profile of clients of the law firm. Like eDoctor, here profile will have many sections which will give information about the clients current and past cases, current status, etc (to be provided). We need to clarify that the app will have profile of clients or lawyers, please let us know. And also from where clients or lawyers will search each other's profile? Will there be a search box? Or contacts feature where they can save each other's profile? Please explain.
We will use hybrid technology to develop the app as native apps are way too costly and time consuming. Moreover, it easy to maintain hybrid technology in case to upgrade or re-developing into other OS. If you have any questions, please contact us.
