Web記事・メール・メルマガ・PDF・メモなどの長文テキストを、タップひとつで音声に変換。通勤・家事・運動しながら「耳で読む」ながら聴きオーディオブックアプリです。 完全無料・アカウント登録不要・広告なし。読みたいのに時間がない——そんなテキストを、目と手が離せないときでも耳からインプットできます。 ■ 一度だけ合成、あとは何度でも テキストは端末内で一度だけ音声(.m4a)に変換してキャッシュします。二度目以降は再生成しないので、オフラインでも、何度でも、すぐに聴けます。通信量もかかりません。 ■ たくさんの取り込み方法 ・共有シート(Safari やニュースアプリの「共有」から) ・アクション拡張「Nagaraで聴く」(表示中のページや選択テキストをそのまま) ・テキストを貼り付け/URLを入力 ・テキスト・Markdown・PDF ファイルを開く ・メール・メルマガの丸ごと取り込み(メールの「印刷」からプレビューを共有して「Nagara」を選択) ・ショートカット/App Intents 連携 ■ メルマガ・長文メールに強い Gmail などで届く長いメルマガも、「印刷」からの共有でまるごと音声化。長文は段落単位で安定して合成し、URL や区切り線などの読み上げに不向きなノイズは取り込み時に自動で除去します。PDF の本文抽出も端末内で完結し、外部に送信されません。 ■ 聴きやすい再生 ・シークバーで頭出し・巻き戻し ・再生速度の変更(0.5倍〜3倍) ・読み上げ位置を文単位でハイライト表示(目で追うことも) ・バックグラウンド再生・ロック画面/コントロールセンター操作 ・スリープタイマー ・「続きを聴く」で前回の続きから ■ 端末内で完結・プライバシー重視 音声合成は Apple の読み上げ機能を使い、端末内で処理します。アカウント登録は不要。行動のトラッキングや広告はありません。ユーザーのテキストを収集・送信することもありません(URLから記事本文を取得する場合のみ、その取得のために通信します)。 ■ こんな方に ・積読の記事や「あとで読む」を消化したい ・通勤・通学、家事、運動の時間を学びに変えたい ・目が疲れる/画面を見続けられないときに情報を得たい ・耳で復習・インプットする習慣をつくりたい さあ、読む時間を、聴く時間に。Nagara で今日から“ながら聴き”を始めましょう。 ※ より自然な読み上げには、iOS の「設定 App →アクセシビリティ→読み上げコンテンツ→声」から高品質音声(Enhanced/Premium)のダウンロードをおすすめします。

Latest update: The monthly plan now purchases reliably. Plus stability improvements. BookAloud is a text to speech reader that turns PDFs, EPUBs, Word documents, and even printed pages into audiobooks you can listen to anywhere — no internet required. Think of it as an app that reads to me: pick a voice, import a document, and BookAloud starts reading aloud immediately, using powerful on-device speech technology so you can learn, study, and get things done hands-free. Whether you call it a read aloud app, a voice reader, or simply a book reader, BookAloud does one thing very well: it turns text into natural-sounding speech so you can listen to books, articles, reports, and scanned pages instead of straining your eyes to read them. It's built for commuters, students, multitaskers, people who find long reading sessions tiring, and anyone who'd rather listen to books than stare at a screen. --- FREE FEATURES --- • Convert up to 3 documents per day (up to 20 pages each) — no account needed • PDF and EPUB import • All voices in 50+ languages, no restrictions on which ones you can use • Read Along view — text highlights word by word as the voice reader speaks • Lock screen and background audio playback • Smart PDF cleaning — strips headers, footers, and repeated page numbers • Sleep timer, so BookAloud stops reading aloud after a set time • Bookmarks to save your place and pick up where you left off • Adjustable playback speed • Document queue, to line up several books and listen back to back • Camera scan for printed books, recognized on-device — nothing uploaded --- BOOKALOUD PRO --- Upgrade to BookAloud Pro to unlock the full audiobook experience: • Unlimited daily conversions — turn as many documents into audiobooks as you want, any day • No page limits — listen to entire books cover to cover, not just the first 20 pages • Word document (.docx) import, on top of PDF and EPUB • Variable playback speed up to 2.5x, for listening faster without losing clarity • Export as an audio file (.m4a) so you can keep or share the finished audiobook --- HOW IT WORKS --- 1. Choose a voice and language from BookAloud's built-in voice reader 2. Import a PDF, EPUB, or Word document, or scan a printed page with your camera 3. BookAloud converts the text and starts reading aloud right away 4. Keep listening anywhere — background audio and lock screen controls mean the reading never has to stop --- SMART PDF CLEANING --- PDFs are full of clutter a document was never meant to be read aloud with — running headers, footers, and page numbers repeating on every page. BookAloud's smart cleaning removes that clutter automatically, so the text to speech engine reads only the content that matters. --- READ ALONG VIEW --- While BookAloud reads aloud, the Read Along view highlights and auto-scrolls to the exact word being spoken — useful for language learning, proofreading, or simply staying focused. You can scroll ahead or back at any time without losing your place. --- WHO USES BOOKALOUD --- People use BookAloud as a book reader for their commute, to get through work documents hands-free, to listen to books while exercising, to have a chapter read to me before sleep with the sleep timer, and as a study tool for reading textbooks aloud while following along. --- SUBSCRIPTION PRICING --- • Monthly: $5.99/month (3-day free trial) • Annual: $39.99/year (save 44%, 3-day free trial) Payment is charged to your Apple ID account at confirmation of purchase. Subscription automatically renews unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions in your Account Settings on the App Store.

Verdict
The clearest difference is in-app purchases: Nagara 読み上げ at none against BookAloud's 3. Nagara 読み上げ also leads on update cadence (every 3 days vs every 3 weeks). BookAloud's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On price and ads there is nothing between them.
