I'm beta testing the new Morpholio Trace

Im not a pro at it by any means but I gave it a five. It's a little complicated at first, in comparison to some others and I really don't recommend it for the iPhone because it is really a professional app that any designer could benefit from. There is a learning curve. There are more simple apps that are probably better for beginners. I give it five stars because it is great in the fact it is so clean in its ui and for the short time Ive been using it, I believe it is perfect for someone to hold their best work. I think it would be a wonderful add for someone that is a professional designer of any kind. It's has to be a little complicated in order for it to have the features that it is packed with. I think once I learn more, and can intuitively know all of the tools and changing them when I need to, I will pay for it with my design projects. So if you know Morpholio well, and have the app mastered, you will be just as happy with the up dated version. You have a lot to look forward to. I'm going to play more with this app. One thing I wish I knew how to send my stencils to creative cloud, or to render a Psd file. It probably is able to be done but I am a novice in that department. Such a beautiful app

Powerful Conceptualization App

Morpholio Trace is an amazing app that I’ve integrated into my everyday workflow. Being an architectural designer I am constantly asked to quickly produce visual ideas to help communicate ideas to clients and the pubic. Morpholio has allowed me to create repeatable styles, that in turn, has allow me to do even more professionally with the app. The power in it for me is the simple yet powerful tools and being able to easily switch between them, almost like using my analogy drawing tools. The Multi PDF importer is one of my favorite features, and being able to swap out individual background pages and update sketches is a huge time saver. In my opinion a lot of effort and thought has been given to how people think while using the app, it’s very intuitive. The subscription is also worth it in my option for all the features. Although I’m a millennial, I’ve had a lot of old school training in the architecture profession and Morpholio Trace allows me to think through that processes I’ve developed, while having the power of undo and digital sketching.

Limiting free version but the true magic is in the full app

The free version is a sample of the full app and what the app can do. As a sample, it does have restrictions and some of which can be misleading. These failures to be clear are not on the developer but on Apple for some very archaic practices in how they describe “in app purchases”.

The developers reached out to me and explained how their subscription service works. I can assure other designers and architects that the full version of the app is where the magic happens. There are no “in app purchases” with the Pro subscription. The subscription does have an annual cost, but for an app that does most everything needed from a design perspective, the $20/year fee is so minimal.

I pay $10/month for my Adobe subscription. That’s 6 times the price of Trace Pro and maybe half the features that a designer and architect may need. In the two hours I have used the Pro version of the app, I can hands down say that this app will fit very easily into my day to day workflow and take my designing to a modern stage.
