I started with the free light version and quickly realized what a powerful tool this was. I ended up purchasing it twice (iPhone and MacBook). Over all this is a great audio notes app. Does what it says it supposed to do and does it well. If you need to reach out to customer service theres someone there ready to assist you within an hour. The details: I have been using this a very powerful tool for over two years possibly three. I put this amazing app through some very tough work situations. On international supplier visits I have to quickly take notes photograph different facilities, equipment and products as well as record meeting meetings. And it has yet to fail me. This is a very simple tool yet extremely powerful at the same time. I consider this one of my favorite apps and it complements my iPhone extremely well. I hardly ever leave reviews but I recently had an issue that was quickly resolved by audionote so I felt that it was time to give them two thumbs up.
