From a clinical point of view, this app can help individuals gain insight (and identify potential sources of conflict) into their relationships by asking basic questions everyone probably should ask themselves before making a serious commitment. It has the potential to transform vague feelings into clear ideas. It can also be used as a relationship builder (a sort of game) for those who have been together for sometime. This could potentially be used with high functioning individuals during therapy.
The app itself is well designed and uncluttered and also has the ability to share the results to Facebook or by Email (which could be useful if thought of more as a game). As a clinician, I would like to see additional features to protect private information such as password protection (this goes for all the apps dealing with sensitive data). Overall, however, I think the app does what it says it will: It increases self awareness and provides insight about your relationships. If you are a psychologist, have you assessed its utility in your clinic?
The Questions App is based on Dr. Martindale's work which can be found on her website [here]
