Noteflow is designed to replace pen and paper. It is a modern digital notebook that lets you get the most from your iPad and iPhone. Use it for taking notes, annotating PDFs, sketching and doodling, plus a whole lot more: Copy and paste from the real world: Use Inkport gen 2 to snap a picture of a whiteboard or writing and convert it into Noteflow's native vector ink. No special paper needed. Then resize, re-color, or edit as if you wrote it in Noteflow. Create layered drawings without layers: Use the highlighter tool to color and shade behind existing ink. Use Color-Select to separate and edit individual colors. It's a much more fluid and natural editing experience than with layers. Use the straight-line tool with a grid for fast and intuitive wireframes and drafting. Drag-and-drop, cloud-storage, and more: Noteflow natively integrates with iOS's file system and drag-and-drop capabilities. Drop photos and text into Noteflow, and drag your drawings into other apps. Store your files locally or sync with the cloud service of your choice. Make Noteflow a seamless part of your workflow, the way you like. SPACE FOR YOUR IDEAS TO ROAM Our vision for Noteflow is simple: to be digital pen and paper. The magic of pen and paper is in their versatility. They are useful for so many things, but particularly for the freeform capture of ideas. Noteflow expands upon this quality. You can naturally do all the things you normally do with pen and paper: take notes in meetings or class, and jot down flashes of inspirations on the go. And you can take that to a whole new level: One of Noteflow’s best uses is for "thinking on digital paper": quickly capture key ideas and concepts, then move and organize them on the screen. Noteflow's vector ink engine lets you scale and edit your work without any loss of quality. Your words and drawings remain tack sharp when zoomed in, giving you a huge effective working canvas even on a single page. There are analogues in the physical world, such as sketchnotes or everyday working on a white board, but being able to fluidly edit and move your ideas around the page is something you can only do digitally. When you represent the ideas in your head with your own personal scribbles on the screen, it effectively becomes an extension of your mind - giving you more room to think. We've designed every part of Noteflow to let you intuitively capture and work on your ideas the way you like. Whether it's dropping in existing information, quickly sketching concepts, or assembling polished presentations for others. EVALUATE NOTEFLOW RISK FREE Rather than just read about Noteflow, go ahead and try it out: We've decided to make the Basic Edition completely FREE. The Basic Edition is a full featured note-taking and sketching app. It comes with the Fountain Pen with black ink, photos, and a standard set of 5 popular fonts for text. Books max out at 20 pages each, but you can create as many as you like. NOTEFLOW+ Upgrade instantly at any time to get: + Inkport + Import and annotate PDFs + A customizable, full color palette, + The Marker, Write-Behind Highlighter and Straight Line tools. + Rotate, Cut, Copy, Paste Ink, and Page Management, + Notebooks with unlimited pages, + Page backgrounds and sizes, + An additional 50+ fonts, + And more! Learn more in the in-app Quickstart Guide. DIGITAL TOOLS FOR A DIGITAL AGE I hope you'll find Noteflow a useful part of your workflow, and that you'll discover new ways to do things with it that weren't easy before. We're very proud of the work we've put into Noteflow, but we're also just seen the beginning of what's possible with powerful new digital platforms like the iPad. Our goal is to push these platforms to their limits to craft useful tools. Tools that can help us think a little more clearly, communicate a bit more effectively, and connect with other in new and enriching ways. Thanks for joining us on this journey! -- The App Makers @ Qrayon.

About

WhiteStar StarDrop

Features
Read full description

WhiteStar's StarDrop is an anywhere-to-anywhere, post-quantum encrypted file transfer system that allows you to send files, pictures, videos and more (of any size of course!) to any StarFiles server. Transfers do not pass through a Cloud, and thus are much faster than other solutions. If your company is already using StarFiles, StarDrop is your mobile solution, fully integrated into the WhiteStar ecosystem. That means quick, fully encrypted file transfers to and from anywhere in the world over the WhiteStar Secure Overlay Network. StarDrop has full end-to-end pure post-quantum cryptography (Category 5) utilizing ML-KEM-1024 and ML-DSA-87 algorithms, alongside SHA-512 and AES-256. This protects your data against not just traditional brute-force attacks, but also secures your data against quantum superposition and factoring. New private keys are generated every time you start a transfers, with unique keys rolled on every packet, making your file transfers incredibly safe, even in hostile environments. Importantly, because WhiteStar StarDrop is not bound by the technical limitations of TCP/IP, and instead uses dynamically scaled packet size over the WhiteStar Network, there is not a 1:1 relationship between keys and content, making it far harder to intercept network frames containing key exchange information, let alone deciphering keying information. This is a marked improvement over older systems that utilize SFTP, AFP, Wireguard and other network security solutions for transferring data remotely. And of course, because it's fully integrated into the WhiteStar ecosystem, you can optionally receive detailed sensor data on data transferred through your organization's WhiteStar Files servers - but importantly, this data ALWAYS stays within your organization's control, is fully private, and is not seen by anyone outside of your company. Plus, StarDrop is integrated into the WhiteStar Dashboard for quick visibility into network traffic (that only your organization can see), email notifications on completion of StarDrops, enterprise-level server access controls and more! StarDrop encryption is automatic, and doesn't require you to worry about encrypting or decrypting your files, making or managing passwords, or teaching clients how to use complex cryptography tools. We do the hard part for you, so you can focus on what you do best and let us handle the heavy lifting of complex state-of-the-art cryptography. Never send secure documents over email again. Use StarDrop instead to easily encrypt and send your sensitive files!
