uFocus is a distraction-free writing environment that supports plain text files and allows you to keep them organized inside libraries. It allows everyone to express their creativity in the most simple way. • Unobtrusive interface: the navigation bar disappears while writing. • Swipe to show the sidebar. Here you can link your favorite libraries and quickly access your documents. • Show text statistics including character and word count and reading time. • MultiMarkdown: easily add headings, quotes, ordered and unordered lists, links, images, italics, bold, footnotes, citations, glossaries and acronyms. You can then export your documents to HTML or PDF. With CriticMarkup and Live Edit Mode you can easily mark removals, additions and substitutions, add highlghts and comments, and accept or reject them. • Fountain: create screenplays with the Markdown-inspired markup syntax and print or export them as PDF with industry-standard formatting. • Highlighting: you can stay even more focused by fading out all the text but the current sentence or paragraph. • Typewriter scrolling: automatically scrolls the text when you get on a new line. • Sound mode: experience the ultimate feeling of a typewriter. • No deletions mode: disable deletions and replacements if your greatest temptation is always to edit your text instead of writing. • Fullscreen: focus on your words and hide everything else. • Choose between three different editor widths, four font sizes and a light, dark, sepia or amber theme, or create your own theme. • Print single files or entire directory hierarchies. If you have any requests, suggestions or bug reports, you're welcome to visit the website through the Support link.

About

Cronus

Features
Read full description

Cronus is the iPhone companion to the Cronus time tracker for Mac. The Mac app watches what you actually work on and builds your day for you, with no timers to start and nothing to remember. This app puts that day in your pocket, and adds the two things a laptop cannot see: the time you spend away from it, and the time you spend on your phone. SEE WHERE YOUR TIME ACTUALLY GOES Open the app and today is already drawn: every block of work, every distraction, to scale. Pinch to zoom into a busy afternoon, swipe sideways to compare it to yesterday. No stopwatch, no tags to maintain, no timesheet to fill in on Friday. FIX A CATEGORY IN ONE TAP Cronus is context-aware rather than rule-based, because a rule cannot know that half an hour on LinkedIn was recruiting and the other half was doom scrolling. When it gets one wrong, tap the block and pick the right category. The correction stands from that day onward, and your Mac follows it. LOG THE TIME YOU WERE NOT AT A COMPUTER A conference, a coffee, a walk that turned into the best thinking of the week. Start an entry from the Track tab and stop it when you are done, or press and hold anywhere on the timeline to fill in a stretch you already spent. ADD YOUR PHONE'S DISTRACTIONS, IF YOU WANT THEM Instagram at 11pm is part of your day whether or not it happened on a laptop. Name an app, pick it once in the Screen Time picker iOS shows you, and the time you spend there lands on the same calendar as everything else. This is entirely opt-in and entirely specific: Cronus only ever sees the apps you point it at, it never gets a list of what is on your phone, and the names it stores are the names you typed. THE WEEK AT A GLANCE Seven days of bars, your categories ranked biggest first, and the apps and sites inside each one. Select a run of them and move them all to another category at once. WHAT YOU NEED Cronus for iPhone requires a Cronus account and the Cronus app for Mac, which is where the automatic tracking happens. The Mac app is free for 21 days of actual use, days you do not open it do not count, and $6 a month after that. There is no purchase inside this app. ON PRIVACY Cronus never captures, saves or transmits an image of your screen, on any platform. On the phone, the only thing measured is how long you spent in the specific apps you added yourself, and Apple's Screen Time API is built so that we cannot learn anything else: iOS hands the app an opaque token, never an app name, so what reaches our server is the label you chose and a duration. Screen Time access is optional and can be revoked in Settings at any time. Read the full policy at https://cronushq.com/privacy
