“Incredibly good app. It auto adjusts sound quality (bitrate) depending on your connection type (WiFi, 3G or EDGE) and sounds quite good on both WiFi and 3G. To thumb up or down a song it's a single touch of the screen and it's easy to bookmark songs and artists. They also have a button to purchase the song on iTunes, all extremely well done. The only minor annoyance was that they asked you...” --teej
“I liked the weather bug and it may have been one of the first apps that I downloaded, but I really wanted a weather app with a moving radar loop, once I got 'my weather' I started to neglect the weather bug. Although I still use weather bug for more detailed information for local forecasts. Also the local outside cameras are excellent. So for the price, free, it is really very good and I...” --dpbutal
“This app is a cool app. There's nothing bad you can really say about it, which is why I gave it 5 stars. You can search your contacts, you can search the web all in one neat little package. Best of all it's free, so I would definitely pick it up if you own the iPhone.” --shivers316
“This is a great little app to have. You're sitting in your car and you love the song on the radio but you have no clue who it's by or what it's called. Bust out this app and it'll identify it for you. Save it and purchase it and there you go...” --shivers316
“I was a Twitterific user before and was quite happy with it. After using TwitterFon for a few days, it's better in a lot of ways. It really wins at ease of use. It's incredibly simple...just like Twitter and that makes it great. I highly recommend everyone give it a try when checking out your options for iPhone.” --teej
“ Love this app but really wish I could look up old daily zens. Unfortunately, as each day passes you lose that respective zen..” --byrocar
“ Hi Guys, I've had this great little app now for a few years and have a lot of data. I would like a way to download the data that has built up to an Excel, Numbers or just a text file. So, how about it? Make a great tool even better. Thanks and let us know. ” --aabaca
“This is an excellent app. You can pretty much do any functions you would normally do on facebook. I like the interface much better as well. It's user friendly. The only down fall is that I cannot tag or add captions to mobile uploads. The mobile uploads also don't ave directly to the phone if you take picture by using the camera button in the Facebook app. I suppose that maybe they will adjust...” --MissAyala
“the game looks amazing and relly fun notice i said looks thats as far as itll go(for now) the hold tilt the ipod thing is a great idea and everything but its so hard to control it i will be unbearble it almost made me wanna smash the blasted thing so for now its just a great thing to look at the levels are full of color and very pretty but you should really wait for a new version to get the fun” --oli16439
“This is a decent app, but not one I use often despite being on Facebook regularly. It just doesn't provide anywhere near the same level of functionality as actually using a web browser.” --ShanePike
