Introduction
This is an application made with Niotron that gives you access to a variety of quizzes. Originally built with App Inventor, this contains 11 sets of trivia questions.
99% of this application, except the feature for looking up trivia quizzes online, can be accessed offline. I have 24 asset files, but they are not even 1 MB yet. We pre-set the questions in a JSON file so that each category has 40 to 50 questions. Then, we randomly draw 10 questions to be asked.
The time limit for each question is 30 seconds each, no matter hard or easy. You can pause the timer for a while, but during that time, the question and options will be hidden, just to prevent cheating.
The categories are divided below. 10 different sets, and 1 set for all.
-
Animals: questions related to different animals and biology.
-
Board games: fun facts and rules about different board games.
-
Computers: basic coding knowledge and how to control computers.
-
Geography - different ethnicities and countries all around the world.
-
History - world history about different countries.
-
Mythology - gods and goddesses from different beliefs.
-
Science and Nature - fun facts about science (physics/chemistry) and their relations to nature.
-
Sports: fun facts and rules about different sport events.
-
Television: questions about shows that you watch on TV.
-
Vehicles: questions about vehicles.
-
All.
There is also a token system that we have just added. Every day you log in, you earn 1 token. When you score 8 points or higher in a trivia, you earn 1 token as well. You can use 3 tokens to eliminate a random incorrect option when doing trivias. We plan to expand this system in the next releases.

Open Source?
Unfortunately, this application is not yet open source. This was originally designed to be in App Inventor. The AIA file will probably be published in May-June.
