It's very fast, easy to use in any language (English or French), it has all you need from contact management software like address book/calendar etc., also supports Viber which I personally love! - No video chat option- Can't share files directly through app.- Price could be cheaper if there were more options available at lower price points as well so that we can expand our business further by targeting other markets too instead of focusing only one market i.e hotels & resorts exclusively; otherwise no complaints except this point since its quite decent product when compared to similar products out here!! If your looking just into contacting people then yes definitely go ahead using Hijffi but not sure about file sharing yet unless they come up wth something soon because currently nothing comes close even though many have tried before me :).
