Download of Ask Oscar 1.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The actual developer of this software for Mac is Kudlian Software. Ask Oscar for Mac lies within Developer Tools, more precisely DB Tools.
From the developer:
Ask Oscar is an application to help develop children's skills in using a branching database. The program allows children to create branching trees containing either pictures, text or both.
This classroom tool uniquely allows you to create, sort, edit, and view the tree all in one single display. Children can visually see the tree growing as they enter their questions and perform sorts.
You may want to check out more software for Mac, such as MIDIviaOSC, DarwiinRemoteOSC or TouchMoreOSC, which might be similar to Ask Oscar.
