📲 iPhone Duo 版＋樂理互動示範：用 Xcode 27.1／iOS 27.1 SDK 重編，摺疊的 iPhone Duo 打開後鼓墊與課程用滿大螢幕，不再是加黑邊的小視窗。樂理樂園五堂課的示範改成按了就有聲音、有動畫；修好 iPad 麥克風課程後沒聲音、離開課程麥克風沒立刻關的問題。送審前在 Duo 模擬器走查修了幾個版面問題（創作台最下面一排大鼓在寬畫面被切掉，連 1.1 的 iPad 截圖都中），商店頁第一次附上 Duo 截圖。
📝 版本說明

🥁 上架 52 天後第一次改版：把 1.0 之後的全部一次送上。主軸是每天一點點——每日一節奏＋節奏花園、裝置端的節奏小教練；再加上演奏回放、16 格節奏創作台、貼紙收集冊與鼓皮、打歌、雙人模式、鼓手熊插圖美術，樂理樂園從 10 課長到 26 課，家長區新增多小孩、家長儀表板與報告匯出，iPad 版面全面重算。
📝 版本說明
1.1 大更新：鼓變得更好玩、學得更多，也更像一位小老師在旁邊
每天一點點
- 每日一節奏：每天一首 30 秒小節奏，打完蓋章；節奏花園會隨著連續天數慢慢長大，沒來的日子它只是打瞌睡，永遠不會枯萎
- 節奏小教練：在裝置上讀你的練習紀錄，用孩子聽得懂的話說「有點搶拍」或「很穩」，排出今天的三件小任務，過關後還會建議快一點或慢一點再試
- 演奏回放：結算後聽一次自己剛剛打的，時間軸上一眼看出早了還是晚了
創作與收集
- 節奏創作台：16 格排出自己的節奏，播放、存檔，還能變成關卡挑戰自己；靈感骰子隨時給你新點子
- 貼紙收集冊：每過一課得一張手繪貼紙，集滿一頁解鎖新鼓皮；節日還有限定鼓皮自動送到
- 鼓伴養成：練習賺的金幣幫小夥伴打扮，隨等級進化
- 打歌模式：跟著小星星、兩隻老虎、瑪莉的小羊的旋律打鼓
全新鼓墊
- 果凍質感的立體鼓面、敲下去有波紋和發光；手機版排成拇指容易摸到的扇形
- 雙人模式：上下兩個鼓面、上面轉 180 度，和爸媽面對面一起打
- 鼓手熊來陪你打鼓，示範時還會點頭
學更多樂理
- 樂理樂園從 10 課擴充到 26 課：音符時值、拍號 3/4 與 6/8、節奏聽寫、切分音、速度術語動物園、鼓件耳朵訓練、拉丁 clave、日本太鼓、複節奏 2:3、看懂五線鼓譜
- 題目可以唸給還看不懂字的孩子聽
- 身體打擊樂：拍手、拍腿、踏腳，不用任何道具就能練麥克風模式
給爸媽
- 親子接力：每回合多一拍，第二回合換孩子出題；家長打的節奏可以存成孩子的挑戰
- 多小孩：兄弟姊妹各自的進度、貼紙與鼓皮
- 家長儀表板：練習日曆、節奏傾向趨勢、建議下一課；一鍵產生本週圖卡與自製鼓組指南分享
- DIY 週任務：每週一個溫和的小任務，和孩子一起在家裡找新樂器
- 自由讚助：家長區可以請開發者喝杯咖啡，完全自願、不解鎖任何功能

1.1 is a big one: more fun on the drums, more music to learn, and a little coach by your side
A little every day
- Daily Beat: one 30-second groove a day, stamp it when you're done. Your Rhythm Garden grows with each day in a row; skip a day and it just naps, it never wilts
- Beat Coach: reads your practice history on the device and says, in kid words, "a tiny bit early" or "nice and steady", plans three small things for today, and suggests going a little faster or slower after a level
- Replay: hear exactly what you just played, with a timeline that shows early and late hits at a glance
Create and collect
- Beat Maker: build your own rhythm on a 16-step grid, play it, save it, and turn it into a level to challenge yourself; the idea dice always has a fresh pattern
- Sticker Book: earn a hand-drawn sticker for every lesson, fill a page to unlock a new drum look; seasonal looks arrive on their own
- Drum Buddy: dress up your companion with coins you earn, and watch it evolve as you level up
- Play-Along: drum to Twinkle Twinkle, Two Tigers, and Mary Had a Little Lamb
A brand-new drum pad
- Jelly-soft 3D drum faces with ripples and glow when you hit them; on iPhone the kit fans out so thumbs reach everything
- Two players: two pads, the top one flipped 180 degrees, so a parent and child can face each other and jam
- Drummer Bear keeps you company and nods along with the demos
Learn more music
- Theory Garden grows from 10 to 26 lessons: note values, 3/4 and 6/8 time, rhythm dictation, syncopation, the tempo zoo, drum ear training, Latin clave, Japanese taiko, 2:3 polyrhythm, and reading a drum staff
- Questions can be read aloud for kids who can't read yet
- Body percussion: clap, pat, and stomp to practice microphone mode with no props at all
For grown-ups
- Family Relay: one more beat each round, and the child leads round two; save the parent's rhythm as a challenge
- Multiple kids: separate progress, stickers, and drum looks for siblings
- Parent dashboard: practice calendar, timing-tendency trend, suggested next lesson, plus a one-tap weekly card and a DIY drum-kit guide to share
- DIY weekly quest: one gentle task a week to hunt for new instruments around the house together
- Tip jar: buy the developer a coffee from the grown-ups' area. Entirely optional and unlocks nothing
