Hello, Thank you for downloading Spark! Spark is a tool to help Pre-K/Kindergarten teachers keep better track of their students. Capture moments of any media type, tag students and development areas, and view these moments in an organized archive. You can even share these moments with parents. Installation: Drag the Spark1.2.ipa file into itunes, then sync your device with itunes. Limitations: - Currently, the application does not support changing user credentials in the settings menu. - Cannot yet delete/edit moments after capturing them. - Tagging untagged moments was working, but was recently broken when adding other functionality this past week. If you have any questions our website is http://stanford.io/1R2vseb! Thank you!
