The application interface of zippyapp was easy enough so that all my customers could download it from their smart phone devices without any hassles or problems! There's no problem with this app as far I have observed thus till now, but we do face very few issues sometimes while using our phones through other applications like Google hangouts etc.. But nothing serious at all! Very good platform which lets you connect directly (no registration)to your customer base within only 15 mins if not less time after posting an advertisement/ ad-posting page via internet!! Highly recommended!! If there should be such feature where user can login themselves into application itself insteadof having separate webpage to open then definitely its worth considering too. Also i don't know why some pages just wont show up when trying them out offline even though they are accessible online!! You will find yourself happy being part off many satisfied users who usezippiap over It has helped me with posting my resume, searching job boards etc so I can find work easily! There's nothing that i dislike about this app as of yet but if you are looking into using it then go ahead because there isn't much out their at all!! If anyone needs help finding employment or wants an easy way just post your information online through zippapp. !
