Hi! My name is Pontus Jacobsson and i am an IOS developer and CEO of the app-development company APPEND.
We are very well familiar with the concept of your application. We have worked (and created) lots of remote APIs (mostly REST based) and the screens and functions doesn't seem to take more than 1-2 days.
Some information about us:
We are a team located in Sweden where we have developers who develop IOS-applications, Android applications, Mac OS applications, Windows applications, VPN solutions, backend APIs (Located on server halls all across the globe) with linux running on them (handled by our linux developers and engineers). We also take great pride in not only great development, but also a our great Creative director and UX engineer who always takes the ideas, go out and test them on the target group and try to find ways to improve it. So if you choose us you don't only get a super well developed app in less hours than any any freelancer here, the whole app idea will be improved with a higher chance of success!
