Review on Mockup.io by Marc Gallner

I like that it allows me to create my own templates for use in our app design process, which saves time! It's not easy at first but once you get used to creating your designs with this tool there is no going back. Sometimes when working remotely from home using VPN or Wifi connections can be difficult as well. If you are looking for an effective way of collaborating while designing mobile apps then look into mockups.io - they have helped us save so much time by allowing us all access to one central location where we work together collaboratively without having to email each other files individually (which would take too long).
