Hukilau Slate App for iPad
'Version one is a simple and easy to use movie slate that allows you to type in the values for all the standard fields like "scene number", "production name" , etc. Shaking the iPad will result in a realistic clapping sound. Version two, slated to come out in a week or so, will have a running LED clock, a scene incrementation button and few stylistic improvements. We encourge users to download it, try it out and send us ideas for features, design and improvements.'
This is a free app.
