The client has a few but very important shortcomings like being unable to set what to alert for via text-to-speech, also one cannot set the volume neither of said text nor for anything else. The user-interface seems a bit off to me, with that annoying background and other elements, but I'm a minimalist kind of guy but I do find it usable. Also the feature to "mask" your voice is not at all highly regarded by me, especially if it cannot be disabled globally on my side as it is usually more annoying than funny. The website serves it's purpose but yes, what the others said about instant clarity what the site is about would help.
