Fantastic content, but poor stability and usability. I love the content, even went as far to sign up for the subscription. However, it constantly crashes, and forces me to clear the cache, or reinstall it just to use it. And the app is poorly laid out, with some illogical UI. The app makes it difficult to search through different podcasts, or to browse all of their offerings. I wish I could give it five stars for the content, but the constant issues I have unfortunately have me frustrated.

Just started using this app and, overall, I really like it. It's fairly easy to navigate and the search function is good. The only complaints I have are lingering expectations I have from other apps. I don't see an option to place a bookmark in the audio version (useful for getting back when using the sleep timer) and there isn't an option to choose SD card storage rather than default phone storage. Otherwise, I'm really happy with this app and the membership thus far.

Hey Joshua! Thank you for taking the time to leave us a review. We're a small team here so we read and appreciate all of them.💚 I know the bookmark option is a thing that's been discussed and is on the road map for a future app update. For the SD card, that's a GREAT suggestion and one I'll share with our tech team to explore further. Be well.

Definitely like the stories I've purchased, but the app is a bit annoying. Even though I've downloaded the episodes while at home, I still have to turn on data or the app won't play them in my car. I don't know if the app has to "phone home," but it's a pain. I'm not always someplace where I can get a signal. Edit 20191230: Developer says the bug is fixed but I still have occasional trouble where the app says something has gone wrong & try again. The only fix seems to be turning on data.

Thanks so much for writing in. We wanted to let you know that we just released a new version of the app on Saturday, December 14, that fixed the bug. You should now be able to listen to serials offline. Let us know if we can help out with anything else! Can you send us any screenshots to when you see "something has gone wrong"?

What's new

In this version:
- Pause audio while using other speaking apps, like navigation to improve in-car usability
- Fixes to issues with Play/Pause button showing incorrect status
- Fixes to audio player inability to exit and vibrating hero text when user has selected not to allow nearby device permissions
