Needs Upgrades To Compete


I jumped at the chance to listen to more books for less. I have audible and could easily listen to 3-4 books a month, so this seemed like a good choice. Unfortunately, it’s lacking some key features which make Audible so great. For one, they should add the ability to bookmark your location. I often use the sleep timer and it’s frustrating to have to try and find your place again the next morning. Also, the playback is not very smooth even when I have all of the chapters of a book downloaded. For example, in the most recent book I listened to, each “chapter” was short, and was only a part of each book chapter, so every few minutes I’d have to wait a bit while the music played before the next track would start playing. I’d also have to agree with other reviews which say the selection is not up to par with Audible. I don’t mind that I wouldn’t have the downloads forever like with Audible, but do mind that the selection is limited. Overall, it’s an ok app, but without improvements I’ll probably switch back over to Audible.

I don't like Otto radio any more...


I don't like otto radio any more, I was thrilled when I discovered something like this had returned I had dearly missed umano and it's articles and another app. I had that was like pandora only for podcasts and at 1st this was like having them both back only all rolled into one .... I've been thrilled about it!! Wanted to tell anyone and everyone about it!!
But lately I've started to fall out of love, almost all my favorite podcasts are NOT being updated anymore, podcasts that are daily and haven't stoped being made and or released , after I tracked them down, that what loved about otto I could listen to all my faves in one place and not have to have a bunch of different apps. to find them or make sure my subscriptions were working properly via iTunes , I could have e
It all in one place plus interesting articles all in one place ...
I love how I could just skim thru the different sections in the " radio for you " section and hear news articles and news of the day... but not only are my fave podcasts not up dating every thing has changed soo much I don't know what there he'll I'm supposed to do any more and I don't like it or enjoy myself all...
I sent a complaint in about my podcasts almost two weeks ago and never got a reply... and sadly deleting and trying to start over only ruined what little enjoyment I had there ...
I'm thinking I should just give up...

(FEATURE SUGGESTION) Almost Perfect!!!


This might be the best podcast app I've ever used, but there is ONE feature that really bugs me while using the app. When you go into your "All New" tab you see the little red dot that says the number of new episodes you have, and it stays there until you have clicked on each UN listened episode.
There should be an option to mark an episode as "played" or "listened" because sometimes maybe you've listened to the episode beforehand on a podcast's website or maybe you are not caught up with a certain podcast and seeing the episodes stack up is very annoying and can quickly become useless when you want to know how many episodes you REALLY have to watch at the time.
If not "played," then maybe it a "dismiss" button or option. It would make the app a 5 star for me.
