I have written an iPhone/iPod/iPad app to help you keep your snake's feeding, shedding and weight recorded. It has loose integration with the calendar to allow you to set alarms for feeding dates.
This app is free and was written because my girlfriend kept losing the pieces of paper she kept our corn's details on. Now it is free for the public to use and I'm open to any suggestions on future features. Feel free to give it a try and let me know what you think.
