Thxs, Seb from McMaster University! ### 5/5 — Very helpful! *2021-06-16* This app is long awaited! A very useful tool to study for exams and certification exams. It is very easy to use. I also love how it cites the answers to where I can go back & study the material. ### 5/5 — Nice Application *2021-06-16* Good use of icons and I appreciate the minimalistic looking of the web application. The colours are eye-catching and the overall structural flow of the app is easy to follow. I am using the app on an iPad so I do suggest optimizing the app to accommodate different screen sizes: - The “back” button displayed on the iPad appears as “b...ck”. I am not sure if this is because the box to fit the words “back” is too small so the app renders the words as “b...ck” due to the lack of space. - Some sentences in the multiple choice options overflow. What I mean is that sentences get cut out mid-way within the container that contains them if the sentence is too long. Maybe try to widen the container or change the font size smaller to make sure the entire sentence is displayed. - If you can remove the “Alert” that pops up when the user presses “back” that could give the user a more smooth experience. Overall, good job and keep up the good work! Ivan ### 5/5 — Perfect app for studying! *2021-06-16* The quizzes are easy to navigate, and I love the textbook references that come up when you answer each question. This would make studying on the go really easy, I’d highly recommend! ## Frequently asked questions about 3fieldbox ### What is 3fieldbox? 3fieldbox is an educational application designed to help users study the main concepts of radiation therapy.
