Nice, but takes sometime to respond when viewing the contacts in your preferred network. It would be nice, if there will be an option in settings to choose a default network contacts to show, so you don’t have to set it everytime you open or restart the app.

Hi Noel, we recently updated the app to optimize the load time and performance. We'd love to hear your feedback. Hope you can download it and let us know what you think.

Previous version better


New version stinks! Takes minutes to respond so it is next to useless. The previous version was much better - gives the info you need and responds quickly. Suggest you bring back the previous version bec this version does not deliver on its promises
