A fellow Artist put me on via link of another Artist on YouTube reviewing it and other Apps. I just went in and overcame the slight learning curve and replaced my favorite Drawing App with this one. ### 5/5 — Great Concept *2026-08-13, version 6.34.1* The tutorials included in this app are worth the price of admission. I’m enjoying the app along with the learning process. ### 5/5 — Mind Map Cheat Code *2026-08-11, version 6.34.1* I love this app for taking notes, especially non-notes like a mind map. I love the easy to use lasso tool and the easy color swap button for IOS. Compared to other infinite canvas apps, Concepts has drastically improved my efficiency. ### 5/5 — Fantastic! *2026-08-09, version 6.34.1* I got this app mainly for my sewing planning and fashion sketches, but I ended up doing so much more! It’s free, with no ads. There is an option to buy pro, but you still have plenty of tools and options without it. There is no limit (at least that I know of) to drawings and folders. You can import photos, and trace over them and color them (that’s what I do when bored), or just doodle! Also great for story planning! ### 5/5 — Great app *2026-08-08, version 6.34.1* Most free value of any productivity app in the App Store for the IPad! ### 5/5 — Solid *2026-08-06, version 6.34.1* Concepts has been a solid go to for immediate conceptualization. I’m particularly impressed with its ability to import imagery, allow resizing, place and erase while building a quick collage to reference for sketching. Since I prefer to sketch out many ideations by hand, these minor conveniences are awesome… because all of a sudden I realize i can sketch right on top of the images and then sketch beside them. I’m testing out using it in tandem with procreate; where more polished collages and are can be done. However, between the two concepts has been a lot simpler to simply start a new drawing and get going. Excellent stand alone, even better in tandem. ### 1/5 — Fake!! *2026-07-30, version 6.34.1* I just downloaded this app. cant even load it. i hate it!! ### 4/5 — Really Nice. Needs a couple adjustments. *2026-07-28, version 6.34.1* It took me a while to warm up to it, but I’m really liking it. I just wish there was an object eraser that deletes entire stroke on contact. I also find the writing experience subpar compared to Goodnotes. The colour palette management is very unintuitive to me. It’s not obvious to me how to add and remove colours from my current palette. ## Frequently asked questions about Concepts ### What is Concepts?
