「My Bookshelf」は「shelfio」に生まれ変わりました。 shelfio(シェルフィオ)は、あなたの読書をシンプルに記録・管理できる本棚アプリです。 「この本、持ってたっけ?」と本屋で迷ったことはありませんか? shelfioなら、手持ちの本をサッと登録して、いつでもどこでも自分の本棚を確認できます。 ■ 本の登録はわずか数秒 本のバーコードをスキャンするだけで、タイトル・著者・表紙が自動で登録されます。キーワード検索や ISBN検索にも対応しているので、電子書籍や手元にない本の登録もかんたんです。 ■ 読書ステータスをひと目で管理 本ごとに「未読」「読了」を記録。フィルター機能で「まだ読んでいない本」だけを表示できるので、積読の解消にも役立ちます。新しい順・古い順の並べ替えにも対応しています。 ■ 評価とメモで読書の記録を残す 読み終えた本には5段階の星評価とメモを記録できます。感想や気づきを残して、自分だけの読書ログを育てましょう。 ■ iCloudで自動同期 本棚のデータはiCloudに自動でバックアップ。iPhoneを買い替えても、大切な読書記録はそのまま引き継げます。 ■ うっかり削除しても安心 削除した本は30日間保管され、いつでも復元できます。 読書好きの方はもちろん、「積読を整理したい」「蔵書のダブり買いを防ぎたい」という方にもおすすめです。 シンプルで気持ちいい本棚管理を、shelfioで始めてみませんか?

For re-readers, not just readers. You read 30 books a year, but can barely remember 5 of them. The note app you tried felt too noisy. Goodreads felt like Instagram for books. You just wanted a quiet place to read, write, and remember. Reading Memory is a slow, private reading journal built around one belief: reading is not about finishing books. It's about what you carry with you afterwards. PER-BOOK "READ TODAY" CHECK One tap on each book you're reading. Your streak grows. Your reading becomes a daily habit, not a guilty pile of unfinished tomes. Per-book checks mean you always know what you read today, not just "did I read." CHAT-STYLE NOTES Capture fleeting thoughts as you read, in a conversation flow. No character limits. No public feed. No reactions. Just you and the book, in writing. REFLECTION CARDS Reading Memory's quiet superpower. Past notes resurface as cards you swipe through. "I remember this," "This still hits," "I had forgotten." Your reading lives on, instead of fading. Forgetting is the default. Reflection is the antidote. MOOD TAGS Eight emotional textures — moved, excited, thought-provoking, comforting, fun, enlightening, melancholic, confusing — to revisit "the books that moved me" when the right moment comes. BEAUTIFUL BOOKSHELF Cover-first grid and list views. Want-to-read, reading, finished, on-hold — your bookshelf becomes a quiet record of who you've been as a reader. SMART BOOK SEARCH & BARCODE Add books in seconds. Search by title or scan barcodes. Powered by Google Books and OpenBD for accurate metadata. READING GOALS & STREAKS Set a monthly or yearly goal. Watch your streak grow. Quiet celebration, no leaderboards. ACHIEVEMENTS Nine subtle badges that mark milestones in your reading life. Earned, not displayed. DESIGNED FOR iOS 26 Built fluently in SwiftUI with Liquid Glass throughout. A reading app that feels like part of your phone, not a website inside it. — MEMORY PLUS — Premium plan Reading Memory's core experience is fully free, including unlimited chat-style notes, reflection cards, mood tags, the bookshelf, and reading streaks. You can register up to 10 books on the free plan. Premium unlocks: ◆ Unlimited book registrations ◆ AI Chat Notes (premium only) A book-aware AI you can have a conversation with about each individual book, with the context of your past notes. ◆ AI Summary (premium only) AI summarizes your chat notes for any book, surfacing the key threads without re-reading everything. ◆ Detailed Statistics (premium only) Genre distribution, mood patterns, calendar heatmap, and pace analytics. Pricing: Monthly: $2.99 / month Yearly: $24.99 / year (save 30%) AI features and detailed statistics are available only with Memory Plus. — WHO THIS IS FOR · People who re-read more than they read · Quiet readers who left Goodreads after the social fatigue · Knowledge workers who want to remember what they've learned · Note-taking minimalists who tried Notion and Obsidian and just wanted something simpler · iOS aesthetes who care about Liquid Glass and craft Indie developer made. No ads. No tracking. No social feed. No Amazon. Read it. Write it. Re-discover it. — Feedback and bug reports: please use the in-app "Feedback" button.
