Learn about the Bible, one lesson at a time.
In Arca, you journey through 100 lessons in ten units, with 1,000 exercises on biblical characters, events, and teachings. Each unit has its own illustration, and the path shows what you've already completed and what the next step is.
LEARN BY DOING
Answer ten exercises per lesson in various formats: multiple choice, fill-in-the-blank, matching, sequences, and other challenges. Check the explanations after answering. Incorrect questions return during the attempt so you can correct them.
CREATE YOUR STUDY PACE
Choose a daily goal of 10, 20, or 30 exercises. Track your progress over the days, earn XP as you complete new lessons, and unlock achievements as you advance. A paused attempt can be resumed on the same device.
REVIEW AND TRACK YOUR PROGRESS
Find suggestions for reviewing completed lessons and check your study history and accuracy by subject. Reviews help you practice again without repeating the XP reward.
SHARE THE JOURNEY WITH FRIENDS
Choose a unique username, find people, and send friend requests. Compare your progress across three rankings: total XP, weekly XP, and among friends. A friendship is only formed after the request is accepted.
YOUR WAY
Choose an avatar and adjust sound, vibration, and animations in the settings. Start as a guest, with progress saved on your device, or create an account to save your completed lessons and XP on the service. Friends and account rankings require internet access.
