If you want to make full use of your Android touchscreen device for speed dialling, XDA forum member simplyapplied has the perfect app.
Sign, is a speed dial widget that let’s you assign a gesture to any contact. Once assigned, all you need to do is activate the widget and make the gesture on your home screen, without even having to look at your contacts!
We developed an enhanced recognition engine to provide a more accurate, consistent, and reliable system to recognize the gestures you assign to your contacts. Sign lets you assign single OR multi-stroke “Signs” to the people you call or text most often.
The full version of Sign is available for $1.99 in the Market or you can try out Sign Lite, the free version of the app which lets you assign 3 gestures.
