Koprol release mobile web version for touch devices
The interface of the touch version is really dead-simple, easy to use and very user friendly, you can immediately navigate through the service without any difficulties. But the site is still in beta so you can still find some bug on the site, although all the basic functionality is provided; so shouldn't be that much of a hassle.
You can start browsing the touch site by going to http://touch.koprol.com from your touch devices and start Koprol-ing immediately. Let us know what you think about Koprol's new touch web on the comments.
