Stay away from unovon. ### 1/5 — Bed quality *2020-05-16, version 1.0.4* I been using for few years but now I have to write a review, very bed call quality, every time I have to register and since last week can’t even register please help update your app ASAP.... ### 1/5 — More improvement required... *2020-01-19, version 1.0.4* Very bad app have encountered so far need lots of improvement ### 1/5 — Worst Ever *2019-10-04, version 1.0.4* Worst ever ### 1/5 — And the award for the worst app goes to .. *2019-02-19, version 1.0.4* Downloaded this app on iPhone. Can’t do anything with this. 1 and 2 numbers don’t work. Can’t help but laugh at this joke of an app ### 1/5 — Worst App .. make you unhappy *2018-11-30, version 1.0.4* Dirty app to make international calls.. No recent calls storage, every time registering the app for 1 min, loud voice in the middle of the call, getting some DID settings failure message when you trying to make second call, No incoming calls, No messages, very rude customer support, no service ticket details and updates, no resolution to any support ticket, not standing on the words when connection taken.. Customer care doesn’t know how to speak with customers. Very bad experience while using the app. No worth for connection. Zero rating for all. ### 1/5 — Worst *2018-07-09, version 1.0.4* Any idea to improve this app? ### 2/5 — Enhancement required *2018-05-29, version 1.0.4* The app could have been developed much better as per the iPhone requirements. This UI does not look either sophisticated or elegant. ### 1/5 — Worst app ever designed *2018-03-20, version 1.0.3* Folks, I am not sure who designed this... it is a piece of work... these guys have no idea about designs and user experience. Once you click the number it takes you to a screen where you need to search for the button to call.. once after you click, it still doesn’t call.. there is another stupid button on the bottom which doesn’t even look like call to make a call... I am sick of this app... I can’t give them below one star, so settling for that. ### 1/5 — Horrible App *2018-03-08, version 1.0.3* I have never seen any app that is so buggy as this one. After the recent update app crashes if I initiate the call and put the app in background. Call history is not updated. ## Frequently asked questions about Unovon ### What does the Unovon app do?
