We have been using the WOTC platform from CMS for the last few years, it has an easy to use platform for the Web and Mobile and can be used in different languages. Patrick and his team are very accessible in case you have any questions, we are very satisfied with the service.
I found CMS to be very easy to work with. CMS's WOTC platform is, by far, the most user-friendly platform I have worked in and quite effortless.
