Welcome Surprise I purchased the CATEYE URBAN Wireless computer for my wife's bike who needs and easy-to-read display with minimal buttons to operate. As I always do, I immediately went online to find a PDF version of the manual instead of the typical small one in many languages that comes with these kinds of devices. I found the manual, but also a link to this app. I decided to download it and take a look and what a welcome surprise it was. CATEYE did a great job putting this together! It makes installation and setup easy to follow (it wasn't overly hard to begin with) and it's the kind of thing I wish more manufacturers would do. No two bike computers are ever programmed the same way and is nice to have this option available at the time of installation and more importantly a future need to reprogram or change the settings. I threw the packaging away so don't know if the fact there was an app available was prominently shown, but I missed it if it was. Nevertheless, this kind of app makes a nice inexpensive bicycle computer an even better buy. Nice job, CATEYE.
