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.

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.

Your calendar should do more than hold your meetings. Khanflow plans your day around them, and makes room for the things you keep meaning to get to. A PLAN FOR YOUR DAY, EVERY MORNING Khanflow looks at your day and fits your goals into the gaps: a run before brunch, two quiet hours for the project that's due Tuesday, ten minutes to finally reply to that text. Every block comes with a reason. Approve the whole day with one tap, or move, swap or turn down anything you like. TIME FOR WHAT MATTERS, NOT JUST WHAT'S URGENT Keep forgetting to call your mom? Tell Khanflow once. It finds a real opening this week, puts it on your calendar, and reminds you five minutes before. It works the same for the gym, guitar practice, reading, a hike, or anything else you want more of. LIFE OS: YOUR WHOLE LIFE, IN ONE PLACE Organize what you care about into areas like Work, Health, Relationships and Learning, with boards and goals inside each. Momentum shows which parts of your life are climbing and which have gone quiet, so nothing important slips without you noticing. JUST ASK "What does my day look like?" "What about tomorrow?" "How's my momentum?" "Plan my week." Answers come back as clear cards you can act on, not walls of text. Paste in your notes and it pulls out the tasks. Import a syllabus and it finds every class and deadline. Prefer to talk? Just say it. SHARE YOUR AVAILABILITY IN SECONDS Trying to find a time with someone? Tap the slots that work and Khanflow writes the message for you. Or send a booking link and let them pick from your open hours. Meeting requests can be accepted or declined in a tap. NOTIFICATIONS THAT EARN THEIR PLACE One to approve your day before it starts, one five minutes before a block, one when someone answers a time you sent, and one at night to set tomorrow, plus the reminders you ask for. Start a block straight from the notification, or push it back ten minutes. Turn any kind off in Profile. STAY IN THE ZONE When a block starts, a Live Activity keeps it on your Lock Screen and in the Dynamic Island. Widgets keep your day and your momentum one glance away. MEET FLO Flo, the bunny, lives in the corner of your screen: listening when you talk, cheering when your day comes together, and nudging you when something's been waiting too long. WORKS WITH THE CALENDAR YOU ALREADY USE Connect Google Calendar or Outlook and keep using them as you always have. Khanflow plans around everything that's already there. Less juggling. More time for your people, your health, and the things you keep putting off.
