The apps have zero traction in Thailand -- the absolute opposite of success. I tried to download YES in Thailand last week and it is not longer available on the iOS App Store. Both Android apps (driver and client) have had fewer than 500 downloads according to the Google Play Store. Neither has been updated since 2015. https://play.google.com/store/apps/details?hl=en-gb&id=com.worldmoto.yesclient https://play.google.com/store/apps/details?id=com.worldmoto.hailyes&hl=en
