Customer Reviews

An incredible app with artistic freedom!

For years, I have presented my schematic architectural designs in sketch format to my clients. I do this before developing a project further in CAD. I recently decided to give up the sketch paper, pen, and colored markers. It seems a bit archaic for our digital age. I researched and downloaded several apps in search of a replacement. I decided on Morpholio Trace Pro, and with my iPad Pro with the Apple Pencil, I haven't looked back! The flexibility this app provides is so impressive compared with its competition. If you're an Architect, Interior Designer, or any design professional looking for the ideal design presentation tool, look no further. As with any new app, there are a couple of features I'd like to see, but I'm sure those will be addressed in future releases. I could go on about the individual features, but suffice to say that this app is absolutely worth the very small investment!


I am an architect in Chicago, and am searching for an app to which I can redline, annotate, and trace architectural drawings from/on. Trace is a great app for several reasons, but has some pitfalls.

The good:
No other app I can find allows for a true "trace" or layering capability. This is fantastic, and very intuitive for architectural purposes.
I LOVE the scalability of the drawings, and being able to measure things right off of the PDFs will be a huge benefit when doing CA work in the field.

The bad:
Importing a drawing set is more difficult that it should, and this is a BIG deal. Importing an individual PDFs works fine, but for this app to actually make a meaningful impact in my daily life, I would need to be able to import a full drawing set (40+ full size pages for a small project). Currently i have to import each page individually, which is a total waste of my time.
Second, I would like to be able to layer a drawing PDF over another PDF. Currently you can only have multiple trace paper layers over a pdf base layer.

Overall a unique app that is in the right direction...but still lacks some qualities.

Great app for drawing and tracing

We have used this app for drawing and tracing during our archaeological field school. Students and professors used the app to draw on site. We especially liked the different tools you could choose and the easy ability to name the files.

The app could be improved by adding a feature that would export the scale with the drawings. I’ve already contacted the developers with this idea and they seemed very receptive to new additions!

If you are an archaeologist, architect, or just someone who likes drawing and designing — consider buying this worthwhile (and very affordable!) app.
