OneScan brings document scanning, a card wallet and practical PDF tools together on iPhone and iPad. Choose from 19 interface languages. SCAN AND ORGANIZE Scan multiple pages, import photos or PDFs, and find documents by name, saved information or recognized text. Select multiple documents to favorite, move to a folder or send to Recently Deleted. Restore deleted documents before permanently removing them. CARDS AND CONTACTS Save IDs, passports, driver's licenses, social security cards, bank cards, receipts and custom records. Start with a photo-import or camera choice, capture each side separately, review suggested details and export A4 copies. Review recognized contact details and export a vCard. Recognition results always need checking against the source. TEXT AND TABLES Automatic on-device OCR makes scans searchable. The selected app language is a recognition hint; available OCR languages depend on iOS. Copy text, create searchable PDFs or export recognized text to Word (DOCX). Word exports text rather than the original page layout. Correct table cells, keep wrapped text in one cell and export formatted Excel (XLSX) with borders, wrapping and an optional header. CSV exports data without styling; original fonts, colors and merged cells are not reproduced. PDF AND IMAGE TOOLS Export PDF, JPEG or PNG, and save page images directly to Photos. Add signatures or text/image watermarks, merge scans, adjust perspective and contrast, organize pages, compress PDFs to a target size and lock the library with Face ID. Standard PDF import creates scanned copies, up to 40 pages or 80 MB. PDF Pages & Passwords works separately with original PDFs: extract selected pages, or export password-protected and unlocked copies after providing a valid password, up to 200 pages or 80 MB. Original files stay unchanged. BOOKS AND RECEIPTS Split book spreads in your chosen reading order, flatten a curved page on device, clean paper backgrounds and reduce fine print or screen patterns. Compare with the original; pattern reduction can soften small text. Review receipt details, keep totals separate by currency and export Excel or CSV. Receipt recognition is a suggestion, not a verified accounting record. LABELS AND BARCODES Review shoe-box style codes, colors, sizes and barcodes, set quantities, view size statistics and export CSV. Scan QR codes and barcodes, count stock, check expected-item lists, import CSV/text and export Excel or CSV. Generate QR and Code 128 labels as printable PDFs or images, and keep local workspace backups. Check recognized labels and counts before saving; unprinted size systems stay unspecified. Scanning, automatic text search, card storage, barcode and shoe-label workspaces, A4 copies and standard exports are free. Pro unlocks advanced document tools.

INSPIRATION The sundial is an ancient instrument for telling the time. It made invisible time visible. Nobody uses one anymore. Sundial sets out to do the same, in a way made for today: it draws time again with shapes, colours and progress. THE NAME The Chinese name, 岁时, comes from Jingchu Suishi Ji, written by Zong Lin in sixth-century China. The book follows the year from New Year's Day to New Year's Eve, and in its pages a year is not 365 identical days but a sequence of named stretches of time. The app does the same: it cuts continuous time into pieces and lays them out in front of you. The English name, Sundial, is that ancient instrument for telling the time. TIME YOU CAN SEE Every stretch of time is drawn as a row of marks: behind you in ink, right now in a single vermilion stroke, still ahead in light grey. No need to open the app. Glance at your Home Screen and you know where you stand. · Seven cycles: today, this week, this month, this quarter, this year, the lunar year and your lifetime · Countdown: from a start date to a target date, see what is left · Count up: from a date in the past, see how far you have come · Overview: today, this week, this month and this year side by side · Lifetime: enter your birthday and a life expectancy, and your life becomes a grid of marks, drawn exactly like your day. Where you are in the day and where you are in your life line up at a glance WHERE YOU LOOK EVERY DAY · Home Screen widgets in small, medium and large, plus extra large on iPad · Lock Screen widgets in circular and rectangular, so a countdown can sit right on your Lock Screen · Full iPad support in both orientations 29 STYLES, 57 PALETTES Bars, thin bars, capsules, stairs, dots, dot matrix, ring, tick ring, ink ring, hexagons, timeline, neon, and motifs from Chinese ink painting: pine, bamboo, plum, leaf, mountains, clover, moon phase and seal. From a single hairline to a small painting, all in the same paper and ink language. Palettes come in Universal, Chinese, Night, Material and Contrast, or build your own from any background and accent colour. Over twenty typefaces, and the figures follow them: stroke weight and line ends match the character of the font. FULL SCREEN AND SHARING Open any item for a full screen view: this year as 365 dots, one for each day, or this month as a calendar of dots. Share any of them as an image. YEAR PROGRESS ON THE FIRST OF EACH MONTH At 9 AM on the first of each month, a silent notification with a card of the year so far. Check this year's progress in Settings any time, share it, or turn the reminder off. YOUR DATA STAYS YOURS Everything is stored on your device and in your own private iCloud database. The developer never sees it and collects nothing. With iCloud sync on, switch phones or reinstall and your widgets are still there. Sync can be turned off at any time. FREE AND PRO The free version lets you create three widgets with the basic styles and every palette. Sundial Pro removes the limit and unlocks every style and iCloud sync, on iPhone, iPad and Mac.
