InkThink is a quantum leap over traditional 'Pen Planner' apps where you just draw over a PDF, or even traditional pen enabled notebooks with templates.

InkThink is what you have been waiting for from an intelligent ink-based diary and planner app - a true pen powered To-Do list and handwritten Calendar.

🗂️ Ink Tasks
Draw your to-do list with your stylus in long ink blocks. Easily add, rearrange, and manage tasks in a tactile, visual format. The bottom of the screen becomes your ink input zone — just write and watch your tasks flow into place. Pro features include Kanban views, Tag filtering and seeing tasks on your calendar.

🌩️ Notes
Capture individual ideas in real time — during meetings, while watching videos, reading, journaling or listening to audio. Notes lets you jot down key points in ink and save them as “thinking sessions” notes. Capture ‘sub-notes’ within each Note for simpler organization - e.g. create a note for each book chapter and your sub-notes for each chapter are your notes for that specific chapter.

📅 Ink Calendar
Draw directly into your calendar. Each inked date can be seen across different layouts - Day, Week and Month. It’s not just handwriting — it’s interactive ink. Pro features include 3 Day, 3 Week and 3 Month views, and split-screen mode.

🧠 Thinking Canvas
Create movable ink index cards on a freeform canvas. Sketch, connect, and rearrange your thoughts like sticky notes on a whiteboard — but smarter and stylus-native. Capture you brainstorm and mind map your ideas. Connect cards and visualize your thinking.

InkThink is modular, intuitive, and built for the future of stylus powered creative productivity. No typing. No distractions. Just your pen, your ideas, and an app that connects and thinks with you.
