The principal thing it lacks is auto-save. You have to manually save what you record, before switching to other apps or locking the phone. Or will be lost. I did a ton of research on dozens of recorders before choosing this one and the Dictate+Connect app, which is better for most purposes. But I use this app frequently. (Particularly for singing melodies because it has a slower auto-record and wont cut me off at every pause). Its solidly coded, never crashes and has the most important features. And manually saving when done has become surprisingly effortless.
