RecallBox is an intelligent tool for organizing screenshots, links, and knowledge, designed for anyone who has too many screenshots, scattered information, and trouble finding things when they need them. Quickly collect important information: You can bring everyday content into RecallBox through automatic photo library import, Shortcuts, the Action Button, manual image selection, or by saving web links directly. The app organizes all materials in a timeline, making it easy to look back, browse, and find what you need. AI-powered knowledge cards: With AI, RecallBox can automatically identify key information in screenshots and links, extract titles, tags, summaries, quotes, tables, and structured content, and turn them into searchable, reusable knowledge cards. Meeting schedules from chats, study material screenshots, payment records, delivery updates, travel pages, web articles, and quick ideas can all be transformed from scattered materials into a clear and organized personal knowledge base. Smart to-dos and reminders: For content that includes times, deadlines, meetings, tasks, delivery milestones, or travel details, RecallBox can intelligently generate reminders and supports local notifications, system Reminders, and Calendar integration. Important items are grouped by Today, Overdue, and the next 7 days, helping you follow up on time without relying entirely on memory. Efficient search and long-term management: RecallBox also supports full-text search, tag organization, favorites, archiving, iCloud sync, and cleanup of processed screenshots. You can keep the knowledge content while removing the original screenshots from your system photo library, making information easier to find, your photo library cleaner, and everyday organization simpler. Give your screenshots, links, and temporary information to RecallBox, and turn scattered content into structured knowledge that is searchable, remindable, and manageable.

About

ReadSlow

ReadSlow isn't another "save it for later" tool. It's a small ritual for actually finishing one article a day — bilingual support is just the handrail that makes that easier. —— Why this app exists —— You can read English/French/German/Chinese..., but don't always have the energy to push through a few thousand words. You'd love to just read the translation, but don't want to lose the feel of the original. Your "to-read" list keeps growing, while the list of things you've actually finished barely moves. If that sounds like you, ReadSlow is built for you. —— How it helps you "finish" —— ◎ Bilingual side-by-side reading A reading space designed for long-form text, with the original and the translation side by side. The default nudges you toward the original; when you get stuck, the translation is one tap away. No guilt for glancing at the translation. ◎ Light rhythm and feedback Date, current streak, a small mark — light feedback that turns "one a day" into a habit. No points, no badges — just the quiet line: "I actually read this one today." ◎ A 7-article reading queue Your queue holds at most 7 articles. Want to add an 8th? Remove one first. This isn't a bug — it's the feature. A number you can see the end of forces one question: "Are these 7 the ones I truly want to read?" —— What it isn't —— Not an all-in-one translator. Not a content library. Not driven by points or badges. Every feature serves a single goal: making it easier to finish today's article. —— One last thing —— In an age where scrolling short videos and feeds has become the default, sitting down to finish a few-thousand-word foreign language article has become something rare, something quietly worth being proud of. ReadSlow only wants to help you do that small thing, once a day. —— About ReadSlow Plus —— To access the premium features, become a Plus member. Subscribe yearly or monthly, and your iTunes account will be charged upon confirmation of purchase. Your subscription will renew automatically unless auto-renew is turned off at least 24 hours before the current period ends.
