Great App, One Problem

Okay so this app is amazing! I use it to convert pictures I take into graphite sketches, and it really helps if you need to figure out dimensions. There is one thing that I think the developers should fix, sometimes the app distorts my pictures. I'll load a picture, finish it, and it'll look perfect inside the app, but on my camera roll it looks like someone turned it 45 degrees and zoomed as far in as they can. It only happens to certain pictures, but I've tried everything, from deleting and restoring the original picture, to deleting and redownloading the app, to changing the dimensions and size of the original picture, turning my phone off and on, etc. It happens maybe 1/10th of the time, and it's not too big of a nuisance, but it'd be nice to not have to cross my fingers ever time I check my camera roll. Other than that, great app, it has many many many different backgrounds and finishing effects, you can change the density and color of overlays, it's just a great app overall. 9.5/10, would recommend to any photographer, artist, whatever. Oh, and it's free for the basic package, which comes with all the overlays, some basic backgrounds, and a customizable eraser and tracing pen. So get this app!

Buyer Beware!!!

It's not very often I get fooled by scamming developers, but these guys got me! First of all, LOOK! at the review titles carefully, and you should notice they are suspicious. Real users don't write this kind of generic fluff. These are "insiders" giving this app five stars!

After buying this app, I immediately found you cannot use ONE aspect of the application without having to pay again, and again! There is not one feature that doesn't cost money, even after you pay for the initial download. You have to pay for EVERYTHING including each color pallet, pen, paper style, theme, shape, and the list goes on!! Every single item on the tool bar will cost you at least $1.99. Want to pick a color? Pay a $1.99. Want to change paper? Pay another $1.99. Want to change your pen style? Pay another $1.99. Want to change from a 4:3 to 16:9 layout? Pay up....yes, another $1.99. Before you can create one document, you'll likely shell out between $10 to $20 bucks....just for starters!

I hope this review prevents you from making the same mistake I did. Don't even pay the initial two bucks to download. There are so many other tools available out there...just pass this one bye. This developer is a fly-by night greedy individual. BUYER BEWARE!!!

Essential for architects and design.

As the last review said this app is amazing! Clean and simple yet enough depth to make it powerful. This is exactly what I need for design, worksessions, site visits and markups. What's most unbelievable is that you can actually peel back to any of your old layers of trace and draw again. One item to improve would be an ability to save a drawing. Besides that it's my favorite drawing app for design and Markups.
Ps. Canary yellow trace is a killer touch.
