Read full description

Lunarium manages your collection, wish list, reading status, Next to Read queue, and reading time with ISBN, JAN, and LUN-13 codes. Organize print books and ebooks together, from books you plan to buy to books you are currently reading or have finished. ■ Add books easily with barcodes and codes Scan an ISBN barcode with the camera to fetch details such as title, author, publisher, release date, list price, description, and cover image. Lunarium supports ISBN-13, ISBN-10, JAN-13, and LUN-13. Books that cannot be found can also be added as custom entries. No barcode printed? OCR can read an ISBN or LUN-13 number printed on a back cover and use it for registration. ■ Add many books with continuous scanning and multi-line input Continuous scanning and multi-line input help register a large collection. Process codes in order and apply shelf, ownership, and reading-status presets as books are added. Skip registered books to avoid duplicates or add them as another owned copy. Use the camera or a connected barcode scanner. ■ Manage shelves, copies, and series Create hierarchical shelves for home, work, ebooks, storage boxes, and any structure that fits your collection. Multiple copies of the same book can have separate locations and statuses. Review series by volume number or release date, organize shelf locations, and check series-level YSA information. ■ Next to Read and reading status Add a book to Next to Read in moments, then drag to arrange your reading order. Start reading or change reading status and ratings from Book Details, library swipe actions, or a barcode scan in Reading Status. Record half-star ratings, reading notes, tags, and completion dates. ■ Reading timer and goals Track reading time with a timer and set daily goals by time or books completed. Schedule goals for selected weekdays or holidays, receive reminders and monthly or yearly reviews, and see progress by calendar, week, month, or year. On supported devices, view and control reading from Live Activities, Home Screen and Lock Screen widgets, and Apple Watch. ■ Smart Lists, search, and filters Search by title, author, ISBN, series, shelf, tags, and more. Filter by ownership status, reading status, rating, dates, and other conditions. Smart Lists automatically collect books that match rules you define. Date rules can use fixed dates or relative periods such as the last three months. Switch between grid and list views, change sorting, or use multi-select for bulk editing. ■ Review and share your statistics Explore totals and trends for your library, purchases, reading completions, ownership and reading status, formats, shelves, and series. Choose the statistics you want to include, check a live preview, then share a polished image or save it to Photos. ■ Use your library on iPhone, iPad, and Mac Scan barcodes on iPhone, then organize your library comfortably on iPad or Mac. iCloud sync can share library data across devices using the same Apple ID. Saved book data and cover images are generally available offline. ■ Import and export with CSV / ZIP Import and export library data as CSV. Full backups can include books, series, shelves, cover images, Next to Read, Smart Lists, reading goals, and reading history. ■ Spotlight, Siri, and Apple Intelligence indexing On supported OS versions, index your library for quicker access through Spotlight and Siri / Apple Intelligence. ■ Lunarium Pro Lunarium has no ads, and its core library management features are available for free. Lunarium Pro adds a larger book-information API quota, bulk metadata refresh, expanded YSA check usage, and shelf PDF417 labels that make changing registration destinations faster. From personal reading records to large collections, Lunarium brings your books and reading time together in one organized library.

System Scope

Features
Read full description

System Scope is a focused dashboard for checking your iPhone's current system status and recent changes. ■ WHAT YOU CAN MONITOR • CPU usage with a live history graph • Memory usage • Used and available storage • Battery level and charging state • Device thermal state, uptime and OS information ■ PRO • Measure a game session using start and end readings: average CPU, memory change, battery drain and thermal state • Extend history from 60 seconds to 15 minutes • Save before-and-after snapshots and compare changes • Export diagnostic snapshots as CSV System Scope has no ads or login. Exact CPU, memory, battery and thermal readings remain on your device and are never transmitted. Anonymous interaction events are sent to Google Analytics for Firebase only if you opt in at first launch, and can be disabled anytime in the app. We intentionally do not offer “memory cleaning” or “speed boosting” features whose effect cannot be guaranteed on iOS. Due to iOS sandbox restrictions, System Scope cannot display per-app CPU or memory usage, list running processes, collect an in-game timeline, or close other apps. Game Measurement calculates device-wide session averages from start and end readings.
