It is hard to understand the navigation of all the pieces of it though. I downloaded this app and it doesn’t even open. ### 1/5 — Crashed before I could use it and won’t delete *2022-07-24* Any time I tried to get into the app it would crash before I could then once I tried to delete the app it wouldn’t and still won’t delete ### 1/5 — Crashes before I even get into the Application *2022-01-11* Not Good…. Also, my Apple Phone told me it wasn’t a secure connection to even write them to tell about this!! On the internet ### 2/5 — Hasn't been updated in 5 years *2020-08-13* While some of the topics are interesting, the presentation is horrible. Aesthetically, the three icons that lead to mind maps are horrendous. The way the "quiz" section is laid out is about as antithetical to positive experience with learning as you can get. You have to pass a certain level in a set amount of time - keep in mind I'm just guessing - trying to learn something new. Yet each time I fail (High concept, high aspiration, cortex, amygdala, etc.) without knowing what the answers actually are (which one I got right!) - which I would like to know. The time limit is ridiculous. Talk about pointless endeavor. I can't understand why apps are not updated for 5 years. I guess I'm a moron because that's all I got from trying the application. Sayonara. ### 5/5 — Interesting selection of book summaries *2013-10-05* Interesting selection of book summaries. Recommended for anyone interesting in learning more about psychology. ## Frequently asked questions about Psychology 1 ### What is Psychology 1?
