No Bluetooth compatibility


Takes an incredibly long time to process podcasts and then it won't work with Bluetooth headphones!

Developer Response

Dear Makoa,
You can enable the bluetooth headphones via the settings screen if you are using the Premium version since it is a Premium feature.
Regarding the duration, as mentioned in the app description, the duration on the encodage operation depends on duration of the initial audio file, if it is a file of few minutes, it will take few seconds, and if it is a file of one or two hours, it may take few minutes.
It depend too of the encodage settings, the more the quality the more the time needed.
You can use the preview function to test long file.
Many thanks

Horrible. Does not work. Other reviews must be fake.


This app does not work with audible and is not easy to use. What a waste of money.

Volume Booster

Johan Winstone

Amazingly simple and a necessary addition if you really need superior volume to be effective. I'm 65 and UVB allows me to hear without an embarrassing, expensive hearing device. I couldn't be happier or ask for more. I've got all my senior friends downloading this software.
