Stake

Stake is a simple quiz that challenges you to match cities with their correct latitude. Each round shows a city card and a vertical ruler spanning from 70° S to 70° N, marked with the Equator, the Tropics and the polar circles. You drag a pin to the position you think is correct and the app displays the exact latitude beside it as you move. When you release the pin, the true parallel is drawn and the distance between your guess and the real location is measured in kilometres. Points are awarded based on how close you are, with a perfect placement earning the maximum score. After eight cities the round is compared to your best score. All eight miss bars share a common kilometre axis, and the largest error is highlighted as “too far north” or “too far south”. A tap lets you view the city among a set of 77 locations arranged in ten‑degree latitude bands, each placed at its true position. The Scores screen plots the average miss of each round on a kilometre axis alongside a line representing one degree of latitude, so you can see your accuracy improve over time. A 12‑second city clock limits each round to under two minutes, and it can be turned off. All content is included in the app and works completely offline. With Stake, your favorites, notes, progress, and personal data are stored only on your device, with no registration, accounts, or cloud synchronization required.
