honestly, there are not as many tool options as there are on the web version, the select tool is really buggy, deleting pixels, adding random stuff that had already been erased, and it is diabolically easy to just exit the drawing and loose all of your progress on what you were editing, and theres only one tracing option, like the fill, cover or contain, so I can't really edit something that you started online with a different tracing option. but other than that, its a great app.

I've been on the app for a few years(TheKindArtist). It's good, made some friends and it's fun to draw. It's an absolute blast, and I love the jokes users have with Bryan(CEO, I wanna say). However, the downside is the glitching I have, depending on the size of the canvas and if it's an animation, too. Not only that, very few mods and a lot of drama. Other than that, it's good, and I appreciate the hard work and the positivity from the staff. Thank you :D Edited

This is overall a great app for pixel art, but there are some things on the mobile version that make it much harder to use than on the website for me. First if all, the undo button is sort of laggy. For instance, it autosaves more than just one thing at a time making the undo button delete more than I did. Second, when I upload pixel art that I've made on the app, it doesn't let me select it on the website to make a custom badge...I'm unsure whether it's like this for all or just me though. Edited

Solid app. It's finicky on a little touch screen, which is more a limit of the medium itself, but I hammered out a totally production ready sprite in about an hour. It's got a lot of room for features, like shading modes, and a grayscale filter to switch on and off for really ironing out the values, while being able to ignore the hues. I also wish you could shrink the spray paint nozzle. Those options may be there and I just haven't found them yet, but for a free app it's really quite good. Edited

Easily the best Pixel Art app I've come across so far. There's daily challenges to creat art to keep you entertained and help you through an artist block, tons of customization options, and it can even allow you to make animations in a simple way. But it's not perfect. You can only Undo so many times, which gets annoying if you want to fix something, and more tools would be welcome.
