About the concept, can you please tell me what is wrong with it so we can think about changing.

Thanks.

Again i want to stress that you did great work. However as to the concept, your what people call a "me too" company. Alot of other companies doing the same thing at the same time. Yes you are a little bit different ,but not enough that most people will pick over .....google or whoever. If you can figure a way to interact with other service and provide features that they not have that might work.

Did you work on this alone or with a team?

Thanks, we work are a team of 2 co-founders: juanpablo and me.
