How does the free tier work?
Ten questions a day, every day, forever. Mixed across Biology, Chemistry, and Physics. The spaced-review queue, your field-day count, and one weekly premium insight are all included. No card on file. Upgrade if you want unlimited practice and the full analytics layer.
What's a field-day count? How do freezes work?
A field-day is any day you complete a meaningful session, at least five correct answers, or ten attempts at 60% or better. Your count grows by one each qualifying day. If you miss a day, a free weekly freeze automatically covers it (up to three banked) so a sick day or test week doesn’t wipe out a long run.
How does the lab choose which question to show me?
The selector targets the zone where accuracy and progress balance - questions tuned to where you actually learn fastest. As you answer, the lab recalibrates per-subtopic so the next question sits in that zone. You can ignore the mechanics; it’s invisible by design.
What's the review queue? When should I use it?
Every question you miss enters a spaced-repetition queue with a scheduled re-attempt date. The queue surfaces a card right before you’d be likely to forget it. Open it once a day; ten cards usually takes three minutes.
How accurate is the predicted Regional score?
It’s an estimate, recomputed after every session, weighted across the three subjects in the proportion the UIL test uses. Predicted scores rise faster than real ones early in the season and flatten as you get closer to your ceiling. Treat it as a directional signal, not a precise score.
Can I turn off the streaks and leaderboard?
Yes. In Settings there’s a single toggle, “Minimize gamification UI.” When on, the streak chip, milestone reveals, audio cues, and team roster all hide. Your underlying state continues to update so you can re-enable anytime.
Are my answers and stats private?
Your answers are visible only to you and, if you joined through a coach access code, to your coach in aggregate. We don’t sell or share data with advertisers, and there are no third-party advertising trackers. Full details in /privacy.
What if I miss a few days?
The first miss is covered by a freeze. If your freezes run out, your field-day count resets to one and your longest-run record stays intact. Pick up where you left off; the queue and your mastery data don’t go anywhere.
How do I cancel?
One click from Settings → Billing. You keep access until the end of your current period. No retention flow, no “are you sure” cascade.
I think a question is wrong, what do I do?
Email [email protected] with the question text or item ID. We re-check every reported question against the original contest PDF. If you’re right, we credit the item, your answer counts as correct, and the bank gets a correction with a Field Note.
