What’s New

Version 5.3


This one is a bit technical. It’s about maths and b-splines and how everything is 10x better than you’re used to. Read on.

You’re probably aware that Concepts uses vectors (i.e. math) underneath every stroke you draw. That’s how you can manipulate things without losing clarity.

With this release, those vectors (called B-splines in our case) are now fully optimized on the fly, as you draw. We call it the Curve Fitter:

- New drawings will store one-tenth of the point data. Old drawings aren’t affected in any way.
- New drawings will load, render and export much faster. Even when you have tons of strokes and you zoom around a lot. Especially noticeable on older devices.
- There should be zero difference in the way Concepts feels while drawing. We went to great lengths to make sure your brushes look and feel exactly the same as before.
- Vector exports (SVG, PDF, DXF) are much improved, so if you’re importing to other vector-based apps (like Illustrator, AutoCAD or your favorite CNC machine), you can enjoy cleaner vectors and improved compatibility.

Some other things we’ve included:

- The canvas UI is now cleaner and faster than ever.
- New gesture options for tap+hold and 4 finger tap.
- Added some basic PPI settings to help manage export sizes.
- Hidden layers are now ignored completely when exporting your drawings.
- Automatically adapt the artboard to image and PDF imports via the gallery.
- Reveal-type brushes can now lock the grain in place, allowing for clean pattern-type brushes.

Such a cool drawing app!

It’s pretty rare for an application that does something so basic to really leverage being in a digital medium like Concepts does. Works super well and finally gives me the ability to individually modify strokes in a way I wish I could from the very first time I started drawing. Great work!

5.3 Review - Not recommended

I use this app daily for writing, sketching, designing and brainstorming.

The current update is not as good as I anticipated. It might be faster as expected however it’s not as accurate when drawing and writing as it used to be on the previous version.

On my iPad pro, when writing or drawing at my normal scale or smaller one, the lines appear to average themselves out with a 0% smoothness on my brush. The lines wobble noticeably and straighten themselves creating undesirable angles and overlaps. It seems like the app is either too slow to register my apple pencil’s movement and figure out the path, or that it’s not reading the full resolution of my pencil’s input.

This never happened before on previous versions. It messes up my lines subtly and requires corrections with each stroke, as for writing, it appears terrible. You’ll need to be writing at a large scale for round strokes or close lines to appear properly.

I hope the developers would fix this for the next versions, but if you have the choice, and wish to have an accurate writing/drawing experience, skip version 5.3 for now. I wish I could revert to 5.2 again.

To me, accuracy is a higher priority to performance for a professional app.
