Good app but a battery drainer


So the good points - works great, callkit integrated, free. Negatives - only one and it’s a major one - major battery drainer. On the battery checker, it shows gs wave drains 29% of my battery, which is way more than apps that I actively use in the foreground for watching videos. Unacceptable really to drain the battery so dramatically for an app in he background. On that basis a generous 4 stars from me, but really more 3.5 stars. Fix the battery drain issue and then it’s a cracking good app. Despite battery app I still prefer it to paid apps like bria as I love it being callkit integrated, so it works just like my normal phone and I never miss a call. But I am thinking of coughing up some cash and either buying acrobits or the slightly more expensive business version of acrobits (name of that app escapes me)

Great app though drains your battery!


This is a useful application and does exactly what I needed, though you have to have it open in the background to receive calls which is fine, but it drains my battery!

Great App ... But Room for Improvement

This is a great SIP client released by Grandstream; easily programmable for remote users / users on the go ...

Also very handy with the Dialplan settings ...

However, for iOS11, the app no longer runs in the background, only runs when opened ... TCP being run as well...

Hope this gets sorted soon ...
