A very basic feature that I was missing in my Android phone is the ability to save a number while I'm in a call. Sure you can go to the home screen, and open up any app with a textbox, but I decided to create a dedicated application.
So, meet Number Saver!
UPDATE: Number Saver got a new look
Basic usage guide:
When you open the app you will get the main screen:
From here you are able to enter the number, copy to the clipboard, and clear the clipboard if it is full. Also, when you open the app, if there is a text in the clipboard it will already be in the text box. So you can press Dial to instantly dial the number
Also, during an active call you will notice the note and pencil icon. Stretching the notification area will give you the option to launch the application.
This app is available for free through the Android market. Donation is always welcome ...
