Intelligent Ink — Handwriting That Moves With You

An innovative toolset for creative productivity. Tasks, Notes, Calendar and Canvas — all through an intuitive, stylus-focused interface. No AI, just a seamless collaboration between your mind and your pen.

BASE Features

Included with One-Time Purchase

Everything you need to organise your day — purchased once, works on all your devices.

Ink Tasks List

A scrollable, re-orderable handwritten task list — just like the real thing. Sketch your to-do's and rearrange with a flick!

Ink Calendar

Write into your day — see it your way! Dynamic intelligent ink that redraws into different day, week and month views automatically.

Ink Notes

Capture notes and ideas while you listen, watch or meet. Each note can include sub-notes for an extra level of organisation.

Ink Canvas

A whiteboard and mind-map canvas to draw out thoughts and ideas — arrange them freely like index cards on a corkboard.

Quick Entry

Quickly add a Task, Note or Calendar item from the Home Screen — your fastest path from thought to captured idea.

Set Task Labels

Create and assign labels to your tasks to better view, filter and organise your workload your way.

Cross Platform Sync

Plan on your iPad, sketch on your Android phone, view on your Windows desktop. Syncs seamlessly — works fully offline too.

Works Offline

You can use InkThink offline - after the 7 day Free trial just go online once to purchase the app and then once done you can continue offline. All data saved locally.

Multi-Day Calendar Events

Calendar entries can span multiple days - ideal for planning your vacation of company offsites. Edit events as needed and delete.

PRO Features
