Galileo Data Entry

This great App allows the social scientist to conduct surveys that all users of the app will see. The users fill out these surveys by reporting the differences (or distances) between a list of concepts. The user reports the distance of each concept to each other concept. This data creates a matrix of responses that can be reconstructed into a 3D map showing a 'conceptual space' using 'R' software, available for free download. This App can be also be used to collect any multidimensional scaling data such as that collected and mapped by SPSS, Statistics Package for the Social Sciences, an IBM product and a variety of other applications that are available for purchase. When the user is done filling out the survey, the user selects 'Exit and Send' and the data that was collected by the App is delivered to the social scientist as a list of pairs of concepts and the differences (or distances) between them. Any questions, contact the author on the support site! Need a custom version for your organization? Contact the author? This software can also be used to collect data for the Galileo System created by Rick Holmes and a variety of students over the years from Michigan State University, SUNY Albany and SUNY Buffalo including the author for Dr. Joseph Woelfel.

Verdict
The clearest difference is price: Ampere at Free against Galileo Data Entry's $0.99. Galileo Data Entry's advantage is update cadence (every 3 months vs every 145 months) and iOS requirement (14.0 vs 16.4). On ads, in-app purchases and device support there is nothing between them.
