標準版和 Pro 差在哪裡？App 免費下載（標準版）。Pro 是一次買斷的內購，不是訂閱：曲目從 3 首增加到 50 首、每首段落從 12 段增加到 50 段；歌曲調整可以匯入 8 分鐘以內的歌（標準版 5 分鐘），並可以匯出（M4A／WAV、AI 去人聲）；節拍器的進階拍型（五連音、六連音、跨拍連音、Clave）；對照表點音名、和弦聽鋼琴等 5 種音色。

曲目存滿 50 首了？有 Pro 之後可以買「曲目擴充包」，每包再存 50 首，最多 500 首。入口在「設定 → 商店」。

Pro Lv2「幫我寫」是什麼？在曲目的「創作」裡，選好調性和曲風，幫你寫出段落和和弦，先試聽再決定套用或取消。Pro Lv2 是一次買斷的內購，要先有 Pro；還沒有 Pro 的人可以買「Pro＋Pro Lv2」一次解鎖。入口在「設定 → 商店」。

換手機或重裝 App，買過的 Pro 不見了？到「設定 → 恢復購買」，用同一個 Apple 帳號就會恢復 Pro、Pro Lv2 和擴充包。曲目只存在手機裡，換手機前請用曲目右上的「⋯ → 匯出曲目…」存一份。

要退款？付款由 Apple 處理，請到 reportaproblem.apple.com 申請。

「請作者喝杯咖啡」是什麼？自由贊助，不會解鎖任何功能，謝謝你的支持！

曲目怎麼傳給團員？在曲目清單長按一首歌 →「分享…」，可以用 LINE、AirDrop 等傳送。對方點開檔案、選「喵喵練團趣」打開就能匯入；也可以先存到「檔案」，再從曲目右上的「⋯ → 匯入曲目…」讀進來。

錄音在哪裡？每一頁最上面都有「錄音」，點開後按「開始錄音」。會同時錄下 App 播出的聲音和麥克風，錄完可以分別調整音量、幫人聲加殘響。錄音存在手機裡，要分享時才會匯出。

Apple Watch 怎麼用？手錶 App 是 iPhone 上喵喵練團趣的遙控器，iPhone 要在附近。可以播放、暫停、開始錄音，左右滑調節拍器的速度和拍號，拍點會用震動提示。錶面小工具可以隨時看節拍器狀態。

調音器或錄音沒有反應？請到 iPhone 的「設定 → 喵喵練團趣」確認麥克風權限已開啟。

為什麼有些「音樂」App 的歌不能匯入？有版權保護（DRM）的歌曲，例如 Apple Music 串流的歌，無法匯入。只能匯入你自己擁有的檔案。

歌曲可以多長？標準版可以匯入 5 分鐘以內的歌，Pro 可以到 8 分鐘。

從 Google Drive 匯入找不到？請先安裝 Google Drive App，再到「檔案」App 的「瀏覽 → ⋯ → 編輯」把 Google Drive 打開。

去人聲要多久？一首 5 分鐘的歌大約 1 分鐘。較舊的機型會比較久，記憶體不足時也可能失敗；建議 iPhone 15 以上使用。

可以用翻譜踏板嗎？可以。藍牙翻譜踏板和鍵盤都支援。歌曲調整：Page Up 回到這段開頭重來、Page Down 播放／暫停；空白鍵播放／暫停、左右鍵快轉倒退、上下鍵切換循環段落。曲目停在「自由拍」時，空白鍵、右鍵或 Page Down 可以繼續。

資料會上傳嗎？不會。所有歌曲、錄音和設定都只存在你的裝置裡。詳見隱私權政策。

What's the difference between Standard and Pro?HelloMusic is free to download (Standard). Pro is a one-time in-app purchase, not a subscription: 50 setlist songs instead of 3 and 50 sections per song instead of 12; import songs up to 8 minutes in Audio Tools (5 in Standard) and export them (M4A/WAV, AI vocal removal); advanced metronome rhythms (quintuplets, sextuplets, cross-rhythms, clave); and hear notes and chords in the Music Theory Chart in 5 sounds, including piano.

My song list is full at 50 songs.With Pro you can buy Song Expansion packs, 50 more songs each, up to 500. Go to Settings → Store.

What is Pro Lv2 "Write for Me"?In Create, pick a key and a style and Write for Me drafts sections and chords for your song; preview it, then apply or cancel. Pro Lv2 is a one-time in-app purchase that requires Pro; if you don't have Pro yet, "Pro + Pro Lv2" unlocks both at once. Go to Settings → Store.

I got a new phone or reinstalled the app and Pro is gone.Tap Settings → Restore Purchases with the same Apple Account to restore Pro, Pro Lv2 and expansion packs. Songs are stored only on your device, so back them up first with ⋯ → Export songs… in the Songs tab.

How do I get a refund?Payments are handled by Apple. Request a refund at reportaproblem.apple.com.

What is "Buy the Developer a Coffee"?An optional tip. It doesn't unlock anything. Thank you for your support!

How do I send a song to my bandmates?Long-press a song in Songs → Share… and send it with LINE, AirDrop and so on. Your bandmate opens the file with HelloMusic to import it, or saves it to Files and uses ⋯ → Import songs… in the Songs tab.

Where is Recording?Tap Recording at the top of any screen, then Start recording. It captures the app's audio and your microphone together; afterwards you can adjust each level and add reverb to your voice. Recordings stay on your device until you choose to share them.

How does the Apple Watch app work?The watch app is a remote for HelloMusic on your iPhone, which needs to be nearby. Play, pause and start recording, swipe to change the metronome's tempo and time signature, and feel each beat as a tap. The complication shows the metronome status at a glance.

The tuner or recording doesn't respond.Check that microphone access is on in your iPhone's Settings → HelloMusic.

Why can't I import some songs from the Music app?Copy-protected (DRM) songs, such as Apple Music streaming tracks, can't be imported. You can only import files you own.

How long can a song be?Up to 5 minutes in Standard and 8 minutes in Pro.

Google Drive doesn't show up.Install the Google Drive app, then in the Files app go to Browse → ⋯ → Edit and turn Google Drive on.

How long does vocal removal take?About a minute for a 5-minute song. Older devices take longer and may fail if memory runs out; iPhone 15 or later is recommended.

Can I use a page-turner pedal?Yes. Bluetooth pedals and keyboards work. In Audio Tools: Page Up restarts the current loop, Page Down plays/pauses; Space plays/pauses, left/right skip, up/down switch loops. When a song in Songs pauses for a free-time section, press Space, right or Page Down to continue.

Is my data uploaded?No. Your songs, recordings and settings stay on your device. See the Privacy Policy.
