Great App … Great Beginnings

I currently rate this app with Fivestars because it is the best I have found on the market at the price point they offer. it is also really a great App! It is only a few years old and it is not marketed nor produced by some big tech company and for that, I award them five stars. Of course, there are some challenges in usability for me as a landscape designer (not enough variety of landscape materials, inability to adjust pattern size relative to the object that is being patterned, popping the length of a curved line for length) but the program makes up for these merits with ease of editing, number of layers available, the magic ruler, and a few other things. I recommend this sketching app with my highest recommendation. I have tried a few and been very disappointed, especially for how much I paid for them. One more thing… The BEST customer service that I have experienced in purchasing apps! I have asked some technical questions and made a number of suggestions for improvement. The tech team has been quickly responsive to my issues and added my suggestions to their list of improvements, which are happening every month or so. Really, I could ask for nothing more… Except to stick to it and keep on improving. 🥰

Five stars means money

This is a favor I’m doing for this company, give them five stars. In truth it would be 3.5 instead of a 5. Why? The usability of the program is still a bit clunky. I must say however there is a massive potential waiting to be unleashed and if handled properly will give the established cad company a good run for their money. Speaking from an architectural point of view drawing objects like walls needs to be more streamlined with much less steps. What would be a big plus is if you could easily assign a dimension as you draw. Another great feature if they could get it to work would be to define an object and give the user the ability to stamp the object at will on the drawing. There is something presently, but it is a bit cumbersome to get to.

On a whole this program is really not bad, I like it a lot and would encourage design aspirants to check it out for themselves. And by the way asking someone for a five star rating is unsavory and a bit distasteful in my book. Your rating should be organically derived on the basis of merit. Ok so maybe I could honestly give them a 4 instead of a 3.5. Apart from the versatility of the product the price / value ratio is extraordinary high.

Go ahead and give them a shot. I’m already convinced.

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
