Trace is THE architecture and design app for EVERYONE.

Ideal for architects, designers, interior designers, illustrators, or members of any creative culture, it helps you create intelligent sketches and drawings to meet all your design needs. Draw on top of PDFs, maps, photos, images, drawing sets, background templates, and more with extraordinary resolution using exceptional designer tools, brushes and pens. Bring new life to your design process and transform your workflow with the ease, flexibility and the magic of digital hand sketching.

Scozzarella ,


Purtroppo si va diffondendo il contagioso virus degli abbonamenti.
Per un uso professionale posso comprenderlo, purché sia garantita una assistenza impeccabile e una continuità di aggiornamenti.
Ma l’applicazione in questione può interessare anche studenti e appassionati a cui dovrebbe essere permesso, come già fanno altre applicazioni professionali, di accedere a tutte le funzioni pro gratuitamente o con un piccolo contributo “una tantum”.

Aggiornamento: desidero ringraziare il team di Morpholio per la immediata disponibilità a prolungare il mio periodo di prova così da potere valutare meglio le funzioni. Al momento la mia valutazione può riferirsi esclusivamente alla qualità del supporto clienti che è da 5 stelle.

Ottima ma...

Indiscutibilmente ottima app, ma la versione pro dovrebbe limitarsi all’acquisto e non ad un abbonamento. Per il resto niente da dire

Ottimo prodotto. Se avesse anche la possibilità di avere tutti i “pennelli” che per esempio ci sono in “Procreate” sarebbe il non plus ultra.
