📋 版本紀錄Release Notes

這一版支援 iPhone Duo，並新增「圓圈地圖」：

• iPhone Duo：以最新的 iOS 27.1 開發工具重新編譯，在 iPhone Duo 的外螢幕與內螢幕都會完整填滿畫面，不再是加黑邊的小視窗
• 魔方學園的練習頁多了一張「圓圈地圖」：把魔方的 54 格貼紙攤平在 9 個圓的交點上，每轉一層，那一圈上的貼紙就跟著滑過去，孩子可以同時看到立體的魔方和攤平的全貌
• 點一下地圖就放大，畫面分成兩半：直拿時地圖在上、魔方在下，橫拿時地圖在左、魔方在右，魔方永遠不會被擋住
• iPad 現在支援四個方向與分割畫面多工

一切照舊完全免費。

This version adds iPhone Duo support and a new Circle Map:

• iPhone Duo: rebuilt with the latest iOS 27.1 tools, so LetCube fills both the outer and inner displays instead of running in a small letterboxed window
• Cube Academy practice gets a Circle Map: the cube's 54 stickers are laid flat on the crossings of nine circles. Turn a layer and the stickers on that ring slide along with it, so children see the 3D cube and the flattened whole at the same time
• Tap the map to enlarge it and the screen splits in two: map above and cube below in portrait, map left and cube right in landscape. The cube is never covered
• iPad now supports all four orientations and Split View multitasking

Everything remains completely free.

用手指轉魔方，這一版練到順手為止：

• 滑動全面重寫：手指拖到哪，那一層就跟到哪，放手才輕輕吸附到位；不想轉了，放開就會彈回原狀，誤觸不再算數
• 魔方上每一格、每個方向現在都有反應——按到中間排，離手指最近的那一排會接手
• 抓到方塊、轉好一步都有輕輕的震動回饋，像握著真的魔方
• 點小鏡子，魔方會優雅地轉半圈讓你看背面三面，在背面照樣能轉、能跟提示

新玩法：限時挑戰！

• App 打亂魔方、倒數計時開始，時間內解開就贏得星星，一關比一關亂
• 時間到也不會輸，只會聽到加油打氣，按一下馬上再試

聲音更可靠了：

• 解題語音與音效不再被側邊靜音鍵誤關
• 接完電話、鬧鐘響過之後，聲音會自動回來，不用重開 App

iPad 修正：

• 掃描頁的返回、手動輸入、切換前後鏡頭按鈕，先前在 iPad 直向拿的時候可能跑出畫面外，現在固定貼在相機畫面的角落，一定看得到

一切照舊完全免費。

Turning the cube with your finger now feels just right:

• Swiping is rebuilt: the layer follows your finger and snaps into place when you let go. Release early and it springs back, so accidental touches never count
• Every sticker and every direction now responds - press the middle row and the nearest outer row takes the turn
• Gentle haptics confirm each grab and each finished turn, like holding a real cube
• Tap the little mirror and the cube gracefully swings around to show its three hidden sides - you can keep turning and following hints from back there

New: timed challenges!

• The app scrambles the cube and the countdown begins. Solve it in time to earn stars, with each level more mixed up than the last
• Running out of time never means losing - you get a cheerful pep talk and a big try-again button

Sound is more dependable too:

• Voice guidance and sound effects are no longer switched off by the side mute switch
• Audio comes back on its own after phone calls and alarms - no need to restart the app

Fixed on iPad:

• On the scanning screen, the back, manual input, and camera switch buttons could sit outside the screen when holding iPad in portrait. They now always stay visible in the corners of the camera view

Everything remains completely free.

魔方學園這次變得更好玩了：

• 打開學園第一眼就是實戰闖關：App 隨機打亂、孩子自己解，沒有實體魔方也能立刻開始
• 新增背面鏡：轉動時同步看到魔方背後的三面，照著提示解題不再迷路
• 手指滑動判讀大幅改善：照著箭頭轉，就會轉出箭頭指的那一步
• 按住魔方時，抓到的小方塊會輕輕彈一下，孩子知道自己抓對了

家長區也有兩個新選項：

• 如果孩子玩得開心，可以請開發者喝杯咖啡。它不解鎖任何功能、不移除任何限制，純粹是心意，由 Apple 處理，而且只出現在通過大人驗證之後的家長區，孩子的畫面上看不到
• 大人驗證除了預設的數學題，現在也可以改用 4 位數密碼（忘記密碼時，刪除 App 重新安裝即可重設）

同時修正了少數裝置上開啟 App 後畫面全黑或卡住的問題。一切照舊完全免費。

Cube Academy got nicer to play:

• The challenge ladder now greets you the moment you open the Academy: the app scrambles, your child solves, no physical cube needed
• A new rear-view mirror shows the cube's three hidden sides while turning, so following hints never loses you
• Swipe recognition is much more accurate: follow the arrow, and you get exactly the move the arrow points to
• The piece you grab gives a little pop, so kids know they caught the right one

Two new options in the parent area:

• If your child is enjoying LetCube, you can buy the developer a coffee. It unlocks nothing, removes no limits, and is handled entirely by Apple. It appears only behind the grown-up gate, never on your child's screen
• Besides the default math question, the grown-up gate can now use a 4-digit passcode instead (forgot it? delete and reinstall the app to reset)

This update also fixes a rare issue where the app could open to a black or frozen screen on some devices. Everything remains completely free.
