Sorry to say, but while this app claims 5 stars, it certainly doesn’t deserve it. First of all, it uses up well over a quarter of my computer’s memory, significantly slowing down its’ operation. I use Shazam’s OSx app and it’s literally constantly using my microphone scanning for sound (for potential songs to match for me) but EVEN Shazam doesn’t hog up nearly 2.5 PERCENT of the memory that eXtra Voice Recorder uses. Nonetheless, this couldn’t and shouldnt be explained by Dropbox syncing either (which by the way is very inefficient and doesn’t update properly across devices as it purports to). Therefore, neither of these likely suspects could or should possibly explain eXtra Voice Recorders’ absurd memory usage. Secondly, for whatever reason this app records audio files in m4a audio format and constantly crashes iTunes when attempting to play them (both applications are on the latest software update). Thirdly, the little menu-bar dropdown window is terribly non-user friendly and is missing many intuitive functions. I’m not even going to start with my suggestions as it’d be a waste of space here… Finally, for anyone looking to pair this app with it’s mobile partner, I’m afraid to say its an absolute waste of time, money, and sanity. This was the one and only attractive feature to me but I just ended up losing numerous important recordings because the mobile app constantly crashes and fails to make recordings (how can a recording app fail at successfully recording?!?). In any case, this app is so simple, yet so terribly designed and nonetheless, for $9.99, it’s 100% totally NOT worth it. I also forgot to mention, I’ve emailed the app creator three times with polite complaints and requests and have only received one response in clearly non-native english claiming they’d fix the problems. It’s likely this app-creator is not dedicating the appropriate time to the app and nevertheless is most likely writing these very endorsing 5-star reviews. The only reason this app gets 2-stars is because it can record audio and sort the files for you, but you can easily do this with plenty of other apps available to you, SO PLEASE SAVE YOUR MONEY AND DONT BUY THIS APPLICATION.
