Study before unlock
A practical learning step before the app opens, not just a hard block.
How it works
Every unlock follows a clear rule.
Set an access gate for distracting apps. Anstogo starts a learning challenge before they open, so focus is not left to willpower alone.
Set questions and difficulty
Choose question banks, volume, difficulty, and unlock duration for your study goal.
Earn temporary access
Complete the challenge to unlock for a short period. Locking resumes automatically when time expires.
Parent controls
Protect key rules and locked-app choices with a parent password when a child uses the device.
Progress

Study time, accuracy trends, missed questions, and performance stats accumulate over time. You see not only less distraction, but more completed practice.
Missed questions
Keep incorrect answers available for review, correction, and practice.
Accuracy trends
Review how your performance changes over the last 7 or 30 days.

FAQ
Common questions before you start.
Why does Anstogo need permissions?
Anstogo uses platform permissions only to apply app restrictions, open required system pickers, and support unlock challenges. iOS uses Screen Time capabilities; Android may require accessibility or overlay permissions depending on the feature.
What does parental control do?
Parental control protects key settings with a parent password, including unlock rules, difficulty, penalties, and locked-app choices.
How do Pro and Sage subscriptions work?
Pro unlocks full question-bank tools. Sage includes Pro features plus AI learning analysis. Subscriptions are managed by the purchase platform, such as Apple ID subscriptions on iOS.
What study data is saved?
Anstogo may save study progress, challenge results, mistakes, saved questions, account profile, and subscription status so the app can provide history, limits, and learning features.
What does Sage AI use?
Sage AI uses the question and mistake context needed to generate analysis and reports. Do not include sensitive personal information in free-form feedback or AI prompts.
What are the free limits?
Free users can use core app-lock challenges and basic SAT/ACT banks, view test-taking tips, keep up to 20 mistakes, and save up to 20 questions. Pro and Sage remove those mistake and saved-question limits.
