Save Everything You Like, Remember It When the Time Is Right Easily save everything in one place: a restaurant you saw on social media, a movie you want to watch, music you discovered, or any content you want to review later. The app allows you to create a personal discovery archive by organizing your saved content under pre-defined categories such as restaurants, movies, music, and more. It sends you meaningful reminders at the right time, taking into account your interests, preferences, and suitable times. This way, your favorite content won't get lost, your plans won't be forgotten, and deciding what to do will become much easier. SAVING TAKES ONE TAP Share the link — you don't even need to open the app. Keepy resolves the content itself and pulls out its title, image and details. IT ORGANIZES ITSELF Everything you save lands in the right category: films and series, food and recipes, shopping, places, events, travel, music. No more digging through a messy list. IT REMINDS YOU AT THE RIGHT MOMENT Keepy doesn't just set a date. It looks at the weather, the time and your context: the film you saved for a rainy evening, the breakfast spot you noted for the weekend, the product whose sale you've been waiting for. RICH DETAIL PAGES Save a film and you get its cast and rating. Save a recipe and you get its ingredients. Save a place and you get its location. You never need to go back to the original link. ALL ON ONE SCREEN Everything you've saved, category by category, in a clean interface. Clear out what's done with a single tap and plan what's left.

Rectoly is the research-focused PDF reader built for Zotero users. Your library stays in Zotero — Rectoly makes reading and annotating on iPhone, iPad and Mac a genuine pleasure. READING MODE Academic papers are often formatted in two columns, making them hard to read on a phone. Reading Mode reflows the content into a single, clean column — without losing access to the original PDF. Jump back to the exact page anytime. ANNOTATE IN READING MODE Unlike other readers, Rectoly lets you highlight, underline, add sticky notes, and draw with Apple Pencil — all while staying in Reading Mode. No need to switch back to the raw PDF just to mark something up. ON-DEVICE TRANSLATION Read an English paper in your own language, in Reading Mode and on the PDF page. Translation runs on this device; the paper is never sent to a translation service. If you agree, translations are saved to your Zotero library for your other devices (using your Zotero storage). The app's translation model (about 2.5 GB) needs 8 GB of memory or more. Translates English papers into the app's 19 other display languages: Hindi by the system's translator (iOS 26 or later), all the rest by the app's own model. TOOLS FOR READING Read Aloud: hear the text in Reading Mode, in the system voice or the VoiceOver one. Choose the typeface and line spacing in Reading Mode. “Darken PDF pages” softens text and paper to gray tones while leaving figures and photos in their original colors when possible. SPLIT VIEW INSIDE THE READER Keep Reading Mode open while glancing at a figure, the original layout, or another section — side by side, all within a single window. No multi-window setup required. RESEARCH THEMES Send a passage to a theme, with its source. Keep the theme beside the paper, or open it as a sheet. Export as Markdown or Word (.docx). ACROSS PAPERS The library column has a new Across papers tab: search the annotations, the text and your handwriting in your whole library at once. FIGURES, TABLES AND A COMPARISON Save a figure as PNG and a table as CSV — one paper at a time, or your whole library in one go. Compare many papers' abstracts, methods, results and conclusions in one table, one row per paper. YOUR DRAFT BESIDE THE PAPER Open the document you are writing (.docx, .doc, .odt, .rtf, Markdown, plain text — password-protected ones too) in a column next to the paper. It re-reads the file every time you save. CITING AND NOTES Copy with page, copy BibTeX or citation keys (Zotero 7's keys and Better BibTeX's are used), and a Notes folder for Obsidian and others — with keyboard shortcuts you can change. ZOTERO SYNC Annotations you create are written back to Zotero automatically. Highlights from Zotero Desktop or other apps appear in Rectoly automatically. Your notes are always in one place. WEBDAV AND LINKED FILES If Zotero syncs your files over WebDAV, Rectoly can now open them — and PDFs you add in the app go to your WebDAV server too. Files that ZotFile or ZotMoov keep in Dropbox or Google Drive open once you choose the folder. WORKS OFFLINE Downloaded PDFs and annotations are stored locally. Read anywhere, anytime — even without an internet connection. SEARCH YOUR HANDWRITING Notes you write with Apple Pencil are now read as text on your device, so you can search them (iPadOS 27 and later). 14-DAY FREE TRIAL → ONE-TIME PURCHASE Try every Pro feature for free for 14 days. Unlock with a one-time payment — no subscription, no recurring charges.
