Scan any document to a clean PDF in seconds then do something useful with it. Most scanner apps stop at a picture of your page. Scanner reads it. Pull the words out, turn a receipt or table into a real spreadsheet, or send the whole document to your AI assistant as one clean file. SCAN TO PDF, INSTANTLY • Automatic edge detection, perspective correction and crisp pages • Multi-page documents: reorder, delete or add pages any time • Your PDF is made on your iPhone, instantly, even with no internet • Import photos or existing PDFs too • No watermarks, no account, no sign-up TURN RECEIPTS AND TABLES INTO A SPREADSHEET Scan a receipt, invoice, price list, timetable or nutrition label, and the rows and columns come back as a proper spreadsheet file, each value in its own cell. It opens in Excel, Numbers or Google Sheets. PULL THE TEXT OUT Tap Text to get every word on the page, ready to copy. Headings, lists and labeled fields keep their structure instead of becoming one jumbled block. Once a document has been read, it's saved on your phone, so it opens instantly next time. SEND IT TO AI, PROPERLY One photo in a chat app only shows one page. Ask AI sends the entire document, every page, as a single clean file to ChatGPT, Claude or any app you choose. Then ask it to summarize a contract, check a bill or explain a letter. HONEST WHEN IT CAN'T READ SOMETHING If a word is smudged, folded or cut off, Scanner marks it [unclear] instead of guessing. You always know which parts to double-check. FIND ANYTHING Search your documents by title or by any word inside them. PRIVATE BY DEFAULT Your documents are stored only on your iPhone. When you use Text, Spreadsheet or Ask AI, the pages are sent securely to our server to be read, and the result comes back to you. No account, no tracking, no ads. SCANNER PRO Scanning and PDFs are free. Text, Spreadsheet and Ask AI are free for your first 10 documents; after that, Scanner Pro (weekly or yearly) unlocks them for up to 1,000 pages a month. Payment is charged to your Apple ID. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your account settings.

Chainkeep is a habit tracker built on two ideas: checking off a habit should take one tap, and your streak should be right. Most habit apps break a "three times a week" habit on the first day you rest. Chainkeep counts it the way you planned it: a week kept is a week kept. Daily habits, specific days, every few days, times per week or per month, and habits you are quitting are all tracked honestly. ONE TAP A DAY • Everything due today on one screen, ticked off in a single tap • Skip a day without breaking anything, or pause a habit for a holiday • Split your day into parts, like morning and evening • Quit habits count your days clean • Hold the app icon to add a habit straight away STREAKS THAT FIT YOUR SCHEDULE • Weekly and monthly targets keep their own streaks • A grace day for the odd miss, if you want one • Habit strength shows how established a habit is, even after a slip • Set a finish line, like 30 or 66 days, and watch it come closer EVERY STAT, FREE • Six months of calendar for every habit • Completion over the last 30 days and the last six months • The days of the week you actually do it, and the time you usually do • Longest runs, totals, and a month in review you can share REMINDERS THAT LEARN • A reminder at the time you choose • Smart nudges learn when you usually do a habit and remind you then YOUR LOOK • 24 colour themes to choose from • Light and dark themes, with a pure black option PRIVATE BY DESIGN • No account, no ads, no tracking • Your habits stay on your own devices • Export and import your data whenever you like CHAINKEEP PRO One payment, yours for good. No subscription. • Unlimited habits (free keeps six) • As many reminders as each habit needs • Archive habits you have finished • Sync between your iPhone and iPad through your own private iCloud Your stats stay free, always.
