3 stars: It's a decent first attempt for an app but missing several important features that still require use of the website, which, unfortunately, doesn't work well or at all when accessed from within the app. Things like topping up and managing direct call numbers should be available as native features. The UI can do with more polish too. The contact circles in the favourites screen look weird. I'd like to see built-in top-up, especially with Android Pay, in the next update. The ability to send/receive SMS would be very handy too. Please continue to work on the app - it has potential to be great. I'll change my review to 5* when you add the abovementioned features.
3 stars: Call someone please tell me the call rate to Nigeria.
5 stars: Let see
5 stars: Nice apps
