5 stars: The service has improved since l commented last. The quality of voice is better, clearer. Actually l use this app for phone calls only and all friends and relatives across the world who have been introduced to it by me are very happy with it. They had never heard of it and were surprised at the excellent quality of voice and clear communication. However, we still have to face disruptions and disconnections occasionally.
5 stars: Good, Video clarity is good as well as audio. In case network is low we are getting hanging or video is getting freeze. Other than that everything is good to use. This is video and audio call application, so kindly increase the security to avoid the data miss use by third party app or people.
4 stars: Has been one of the most clean apps to converse and be happy without any lag and issue. Performance is good with network and less latency issues.. needs some work on the notification part. As sometimes the incoming text or call is not at all visible until you open the app. Needs work.. but terrific otherwise.
4 stars: I have been using this app for some months till now. And the connection quality on audio calls is showing excellent in most of my communication with relatives. Since many of my friends who are familiar with other apps but not with bottim are being informed & invited to use this app by me. Keep up with quality and work for excellence. I still don't use the video calls & unable I am to say a thing. I, therefore, rate you ...
