All the ads make the app crash. Its free - therefore it comes with ads; I get it and accept it. But when the quality of the app goes down for a larger quantity of "possible" profit, then your ratings will drop also.
With all the crashing, I find it useless to use for long periods. I have a ton of space available in my device, and always update, so its not that. Its just the crappy ads that run every 30 seconds. After two minutes of having the app open, it crashes and saves an empty "recording" with no sound. I have other short recordings that do play sound and only because I stopped the recording before the app crashed. I recommend only recording 30secs max if you want it to stay around.
Fun to use, just expect the crashes and lots of ads.
