Two-handle answers
No single guess allowed. Slide the left and right handles along a scale such as 1,000 to 15k. YOUR BAND prints the span, for example 5,900 - 10,100, plus how wide it is.

What is inside
The Treasury: six tools in one tomb
Every item below is a screen or control you meet in the first ten minutes of play.
II
A confidence you commit to
Choose the percentage before the round. A "90% sure" badge stays in the corner of every question, a reminder of the promise your bands must keep.
III
The amber tick
Submit and an amber tick drops onto the slider at the real value. A one-line story follows: the Challenger Deep, deep enough to swallow Everest with room to spare.
IV
A verdict, not just a score
The round card says Overconfident, underconfident or well calibrated, then explains it in plain words: you said 90% and hit 80%, so widen your bands.
V
Topic and difficulty dials
Switch topics on or off, from Earth & Water to Geography and Physics. Set the round length and let difficulty stay Adaptive, or tap to change it.
VI
Question-by-question replay
Each card shows your range beside the truth, tagged HIT or MISS with points. Flip on Show misses only, then Flag all misses to queue them for review.
Technical analysis
Inside the scoring chamber
Every question asks for a number: the depth of the deepest point in the ocean, the length of the Nile, the diameter of the Sun. The unit is printed under the question ("Answer in m"). You do not type a guess. You stretch a band across a labelled scale, and the app mirrors it back as a min-max pair with its width, such as "30% wide".
Before the round you pick a confidence level, and the question header repeats it as a "90% sure" badge. That figure is the contract. If you say 90%, about nine of ten bands should contain the truth. Points reward both landing and staying narrow. In one sample round, a band that caught the answer paid 88 points, a wide miss on the Sun's 1.39 million kilometre diameter paid 0, and an answer just outside the band on the ocean depth question still earned 40.
When the last question closes, the Round result screen sets what you claimed against what you hit. It also admits that one round is a small sample. The profile tab pools every answer at that confidence setting, and the Practice screen shows the running totals: answers logged, typical width and average points.
