David Colin
Freelance Web & Mobile developer
I’m a freelance web & mobile developer. I help startups, small businesses, and agencies bring their ideas to life.
Have a project, an idea or a problem you’d like to discuss?
I have been working in web and mobile development since 17 years ago. I previously worked in Agencies and Startups.
Today, my job is to assist you in the design and production of Web and Mobile applications (Android and iOS) and to ensure their referencing on stores or search engines.

I don’t usually give reviews and I am not easily impressed. This app is perfect. The ads are short and unobtrusive/ there are no ads on the actual score page. The preset score options are really handy when the 7 year old wants to be score keeper. Finally I love that you have to confirm that the game is over before it takes you to the results screen in case the wrong number was clicked.
