Nope. – Mumblefy Review

I was considering paying for your app since it is the only solid iOS Mumble client. Then I saw it was $4.99 just for no ads and I hesitated. Then it played a full screen video ad that blasted away my eardrums while I was in a call, and I uninstalled it. Until you make your ads unobtrusive and SILENT, and charge a more reasonable price, I'll be moving to Discord.
