ReadSync
Read full descriptionHide full description
ReadSync remembers where you stopped reading โ on every device. Open a PDF on your Mac, read to page 120, then pick up your iPhone. ReadSync opens the same document on the same page. Your highlights, notes and bookmarks are already there. WHY READSYNC โข Your reading position syncs automatically through iCloud โ in the free version too โข No account to create, no subscription, no company server holding your files โข Works completely offline โ syncing is a layer on top, never a requirement PICK UP WHERE YOU LEFT OFF โข A Continue Reading row at the top of your library, most recent first โข A Home Screen widget that opens the document on the page you left โข Nothing to press: the page is saved as you read and travels with you โข Handoff: the document open on your Mac appears on your iPhone, and opens on the same page READING โข A quiet reader that hides its controls while you read โข A reading lock that turns off selection, highlights and notes, so you can scroll and zoom without triggering anything by accident โข Keep the screen awake while a document is open โข Night mode that darkens the page without draining the colour from your highlights โข Single or two-page layout, vertical or horizontal scrolling โข Adjustable default zoom โข Translate any passage you select into your own language, on your device with Apple's built-in translation โข Look up any word in the dictionary without leaving the page โข Password-protected PDFs open too โ remember the password once, in your iCloud Keychain, and your other devices open them without asking HIGHLIGHTS AND NOTES โข Five highlight colours โข Attach a note to any passage โข Every highlight and note in one list โ tap to jump straight to the page โข Export everything from a document as a single file, to Notes, Mail or Files โข Nothing is written into the PDF itself; your original file stays untouched FINDING YOUR PLACE โข Full-text search inside the document โข The PDF's own table of contents โข Bookmarks for the pages you want to come back to YOUR LIBRARY โข Add files from Files or iCloud Drive โข Open a PDF in ReadSync from Mail, Safari, Messages or any app's share sheet โข Leave a file where it is, or copy it into ReadSync so it syncs across your devices โข Cover, progress and page count at a glance โข Sort by last read, title or date added โข Search your library by title READING STATS โข Total reading time, and how much of it was this week โข A chart of the last seven days โข Progress for every document you have started FREE AND PRO The free version is a whole reader, not a demo: iCloud sync, night mode, search, table of contents, bookmarks, translation and all five highlight colours, with room for 5 documents and 10 highlights or notes in each one. ReadSync Pro lifts both limits and opens reading stats and note export. It is a one-time purchase โ there is no subscription. A limit only ever stops you adding something new. Everything already in your library stays open, in full, whether you buy or not. PRIVACY ReadSync is built entirely with Apple's own frameworks and stores everything in your private iCloud database. Your documents are never uploaded to anyone else's server. Anonymous usage statistics are sent only if you agree when asked, and never include your files, page contents, notes or highlights.

Most to-do apps help you collect tasks. Zoro helps you cut them. Zoro is a task manager for people who run more than one project at once: founders, freelancers, builders wearing too many hats. It keeps the few agile ideas that pay off for one person (priorities, effort sizes, work-in-progress limits, a weekly review) and drops the ceremony. No sprints, no story points, no velocity charts. WORK ACROSS PROJECTS, NOT INSIDE THEM Two spaces, personal and business, hold as many projects as you need. Every task carries a priority (P1โP3) and an effort size (S/M/L). One board holds product work next to invoices next to the launch plan, and the highest-leverage work rises to the top no matter which project it belongs to. THE METHOD โข Three things today: you can only finish a few things a day, so Zoro asks for three โข Size by effort, not time: S, M, L. Estimates in minutes are a trap โข One cut at a time: a work-in-progress limit keeps you finishing before starting โข Let nothing rot: tasks age visibly, so the work you're avoiding stares back โข Sharpen weekly: a Friday review that reads your week back to you PRIVATE BY ARCHITECTURE Your tasks live in your own iCloud, and Apple syncs them between your devices. Zoro has no servers that hold your data, no account to create, no analytics, no tracking. The App Privacy label reads "Data Not Collected" because there is nothing to collect. We couldn't read your tasks if we wanted to. THE WEEKLY REVIEW Every Friday, Zoro assembles the facts: what you cut, what you added, what's been open too long, what you keep deferring, whether the big things are stalling. You reflect (plus, minus, next) and close the week. Over months, History becomes the honest story of how you actually work, and Trends shows the shape underneath. FREE, PROPERLY The whole method is free: unlimited tasks, unlimited projects, iCloud sync across iPhone, Mac, and the web, effort sizing, aging, the weekly reflection. No task caps. Ever. ZORO PRO Pro goes deeper into the practice: the full weekly insight cards (aging, avoidance, effort mix), every week kept in History, Trends over time, the stats dashboard, subtasks, and custom statuses. $2.99/month, $19.99/year, or $59.99 once, with a 14-day free trial. Zoro is for people who want fewer tasks, done. Not more tasks, managed. TERMS & PRIVACY Terms of Use (EULA): https://www.getzoro.app/terms Privacy Policy: https://www.getzoro.app/privacy
