Since a few days available in the App Store: The app „My Price Tag“ quickly draws a sign, price tag, small poster, or promo sheet with your iPhone or iPad and displays it.
Enter a text and a price, press „Display Sign“ and you’re done!
Additioinally you can use gestures to adjust the position and the size of the texts. An image can also be integrated into the sign.
The app offers various possibilities of color design and also a large selection of fonts for the display of the sign.
Have fun with it.
