3D Text @ Logo is a free iPhone app developed by VECTOR SYSTEMS BG EOOD. This app allows users to write any text on any chosen background. With over 100 fonts to choose from, users can easily customize their text by moving, rotating, and resizing it on the screen in real time. The app also offers a gradient text color feature, allowing users to select multiple colors for the front and rear side of the text. Additionally, the 3D shape of the font can be inflated or deflated according to the user's preference. Users can even import their favorite image to use as a background and save the result as a new image in their photo library. For added fun, users can click on the screen to see the letters explode. The app is suitable for kids and performs well on older devices like the iPhone 4S and iPad 2.
