About this app

Think, plan & create – Concepts is a flexible vector-based creative workspace/sketchpad where you can take your ideas from concept to reality.

Concepts reimagines the ideation stage – offering a safe and dynamic workspace to explore your ideas, organize your thoughts, experiment with and iterate designs before sharing them with friends, clients and other apps.

With our infinite canvas, you can:
• sketch out plans and whiteboard ideas
• make notes, doodles, and mindmaps

Ratings and reviews

I'm still a learner, so I haven't fully unlocked everything this app can do, but as far as I can see, this is the ultimate mobile app for creative purposes! I have a Galaxy Note, so it pairs perfectly with the stylus! One improvement I hope the developers add, since built-in-stylus' are becoming more common place, that we can plug into a monitor for Samsung Dex to see and use the phone as a drawing tablet! Devs, if you see this, please include me in the beta!

Free version is not vector. You can only draw freestyle. There's no line, circle, rectangle, or other shapes to use. If it had shapes and the ability to manipulate it, I would have at least bought the vector pdf export version for $5.00. $29.99 is too much money, especially since a reviewer said it's possible to loose your one time payment. I hate knowing I could loose my lifetime payment and nothing can be done about it. I will not recommend this product to anyone!

The free version is ok enough for doodles, but not much else. It is not possible to buy a full version of the app. The most you can buy is an "Essentials" version that gives you only a few extra tools, and only for one device. Everything else is locked behind a subscription. It fits my needs enough, but I'm disappointed I can't just buy a copy and be done with it.

What’s new

2026.1 - Usability improvements

This release improves Shape Recognition by adjusting the snapping behaviour of the shapes and making sure the starting point of lines does not shift when a line is recognised.
