A precision world clock styled after classic aircraft instrument dials, with 11 widget designs for iOS, iPadOS, and macOS.
Drag any hand on the dial — every other city's hand rotates together with it, while the hour track stays fixed. Tap the center of the dial to snap back to your current local time.
Add or edit cities inside the app first — each widget instance reads its city list from there, so you can configure different widgets for different city sets.

A puzzle about a line with two live ends: every piece fuses onto one of them, and you have to land the head on one marker and the tail on the other, exactly.
Each piece carries the line a fixed distance — one, two, or three cells. A piece that reaches three cells simply cannot land on a marker two cells away; it would overshoot. Close to a target the game only deals pieces that can actually finish, so if nothing fits an end, that end is genuinely blocked.
There are two ways to lose. Either the piece in your hand fits on neither open end, or your own line has walled off the last route to a marker — the game checks that after every move and tells you immediately, instead of letting you play into a dead end for another ten pieces.
No. Every statistic is kept on your device, and the game is fully playable signed out. If you sign in later, your totals are sent to Game Center then.
The game is endless, so the number worth watching is your career total rather than the payout for a single round. A win is worth tens of points, not hundreds.
