The Slingshot Organizer is now available as a mobile app! Complete with the hand-drawn art, menstrual calendar, and radical dates from history that you love about the paper version. If you have not seen the paper version - you are in for a treat.
The mobile version is functional and reliable, but still a work-in-progress. Please let us know what you think and send us suggestions you have to make it better!
The app syncs with your google calendars so all dates added in either this app or google calendar will appear in the other automatically. A gmail/google account is required.
