Pros: “Spaced repetition” is a great concept for helping students maximize their study time.
Cons: Most of the best features are only available as paid content, and the app automates some important opportunities for self-reflection.
Bottom Line: A solid concept, but K–12 students and teachers might be better served by other free apps' features.
Keep in mind that Synap's developers are based in the U.K. and most of the built-in content is geared toward students in the U.K. system, especially at the high school and college levels. This app's premium features include something called "spaced repetition," which automates the process of students reviewing and revisiting content over time with a focus on the questions they previously missed.
If you can afford the subscription for your students to use this tool, great; if not, talk with your students about developing their own habits for spaced repetition. How do you keep track of the questions you've missed? What should you do next when you miss a quiz question? Ask your students to develop their own quizzes and talk about how they should study the questions and how often they should revisit each based on how well they performed on previous quizzes. Also, talk about what kinds of quiz questions work best in a flash card app such as this.
Synap is a U.K.-based app for test review, or "revision" in British English. Its quiz questions are organized using a method called spaced repetition that encourages users to practice over time. Once they create an account, users can create their own quizzes, search other users' quizzes, and purchase access to expert-built quizzes. You can "favorite" quizzes and organize them into playlists, or folders, to organize related content for ease of use. Most of the built-in content is geared toward British secondary students and university students: The app's home page especially features questions for the U.K. education system's General Certificate of Secondary Education, the British medical education system, and other questions developed by Oxford University Press.
The app itself is free to download and offers some limited features for creating your own quizzes and sharing them publicly. The paid version offers significantly more features, including access to premade question sets and more ways for teachers to share quizzes and track their students' progress and their scores.
The real point of Synap is to end cramming for tests: It's a study tool, but its real purpose is to help students foster good study habits by spacing out their studying over time. Its features for creating quizzes from existing content are pretty good, and it's nice that you can neatly organize your own content and others' quizzes into playlists for easy access. Unfortunately, most of the app's features that best support good study habits -- such as the tracking features and offline access -- are only available in the premium edition, which can feel spendy when other free apps do the same thing. The free version only lets you access these useful shuffling features once a week, which doesn't seem more helpful than developing your own habits for deliberate, self-directed study.
Also, keep in mind that most of the built-in content is more geared toward students in the U.K. education system around the world. If your students are working in that context, this trove of content will be a boon to their studying; if not, there might not be much here that's worth your while. Overall, this is a cool concept for helping students study, but perhaps look elsewhere for tools that better help K–12 students develop active, self-reflective study habits.
