User reviews

Perhaps the greatest apps for art

If you happen to be an aspiring cartoonist/artist like me, then this app is certainly what you're looking for! I'm a huge fan of the infinite canvas feature.

I often like to draw my cartoons on this beautiful software (alongside with ibisPaint and Kleki), and I couldn't thank TopHatch enough.

Losing functionality

The app used to be quite good, and I used it for planning out large maps with high detail. But now when I want to export, it is stuck on “safe” mode, so I can no longer export at higher dpi, making it useless for me now. Really disappointed

A enjoyable design

I’m very very new to drawing but,so far this app has been very easy to pick up, and all the lines being vector based make editing your work soooo much easier and it’s not even half as daunting or committal as physical drawing, as if you mess up a line, or dislike your spacing later in the peace then it’s totally fixable. also love the bend a line tool, great for cleaning up edges

Bad

When I tried riding, it wouldn’t let me and when I tried drawing, it wouldn’t let me. The only only thing I could do was put shape

Richtig starke App fürs Studium und privat

Ich nutze Concepts fürs Studium und auch privat und bin echt begeistert. Das Schreibgefühl mit dem Stift ist richtig angenehm und natürlich. Dazu kommen super viele coole Funktionen, Features und Werkzeuge, man entdeckt ständig was Neues. Die große Leinwand ist klasse für Skizzen und Ideen.

Das Einzige, was ich vermisse, ist ein Seitenmodus mit einzelnen Seiten wie bei GoodNotes, also ein klassisches Notizbuch-Format. Gerade für Vorlesungsnotizen wäre das perfekt, weil man dann nicht aus Versehen Notizen verschiebt.

Aber im Großen und Ganzen: absolute Empfehlung, 5 Sterne!
