Digital whiteboard
Write, draw and explain exactly as you would on a real board — with pages you can add, flip through and keep for the next class.
TutorBoard turns any Android tablet or phone into a teaching board. Write and draw your explanation, open the PDF or website you're teaching from, and keep both on screen at the same time.

Most lessons need a board to explain on and material to teach from. TutorBoard gives you both, without juggling apps mid-class.
Write, draw and explain exactly as you would on a real board — with pages you can add, flip through and keep for the next class.
Open the textbook PDF from your device or pull up any website. Your material stays right where the lesson is happening.
Show any two of them side by side — the chapter on one half, your working on the other. No switching, no lost train of thought.
Write with your finger or a stylus. Pinch to zoom in on a detail at the back of the room, and pan around — each page remembers exactly how you left it.
Pick any two of Web, PDF and Whiteboard and they share the screen. The exercise stays visible while you work through it — which is exactly how students follow a solution.
Type in an address and the page opens right inside TutorBoard. Switch the annotation layer on and you can mark up the page itself — circle the term that matters, underline the definition, point with a laser.
Open a PDF from your device — a 300-page textbook is no trouble — and jump to the page you need. When the lesson is done, save the board and pick it up next week.
No setup, no sign-in, no manual. Open it and start explaining.
Pick a PDF from your device or type in a web address. Skip this entirely if you just want a blank board.
Tap Split Screen and choose your pair — say, PDF and Whiteboard. Your material stays put on one side.
Explain it with the pen, add pages as you go, and save the board when you're done — or don't, and start fresh tomorrow.
The same app on a phone in your pocket and the tablet on your desk.



Split screen on a 10-inch tablet — chapter on the left, your working on the right.
TutorBoard has no accounts, no analytics and no advertising. We don't run a server for it, so there's nowhere for your notes to go — what you write stays in your hands, which is how it should be when there's a classroom of students in front of you.
No. TutorBoard is built to work with a finger, and a stylus simply gives you finer control if you have one. Pinch to zoom in when you want to write something small and neat.
Both work. A tablet gives split screen more room to breathe, but everything — whiteboard, PDF, web and split screen — runs on a phone too, in portrait or landscape.
The whiteboard and your saved boards work completely offline, and PDFs already on your device open without a connection. Only the web viewer needs internet, for the obvious reason.
Wherever you point them. Saving opens Android's file picker, so you can keep boards in your device storage or your cloud drive. The file holds every page and stroke, and TutorBoard reopens it exactly as you left it.
Yes. Turn on the annotation layer in the web viewer and you can draw over the live page with a pen, highlighter, underline, text and a laser pointer — useful when the diagram you need is already online.
Android 9.0 (Pie) and newer, on phones and tablets.
Nothing. There are no ads, no subscription and no paid unlock.
An interactive whiteboard for tutors, teachers and trainers — free, private, and ready on the device you already carry.
