Artists with unpopular art programs , show yourself!

[Capybara]

Unfortunately my go-to program is Clip Studio Paint, which is pretty mainstream. So was the program I used before it, Paint Tool Sai/Sai 2. But I do have some experience with this.

- AzPainter 2 is a program I tried before and want to get back into. It's primitive but the tools allow you to make sort of old oekaki-ish type art. I have no idea how else to explain it.

- GIMP. Bad name, okay editor. For several years I used an outdated Mac given to me by family, and I couldn't really run anything good back in the early 2010s... So GIMP was my go-to.

- Colors 3D is REALLY GOOD. The 3DS version, at least. It was the reason I got a 3DS a decade ago, it's a good application and I loved it. If my 2DS could charge, I'd still use it today. I own the Switch version, but despite being better I haven't really broken into it... Especially when the stylus is bent and I'd have to get a new one. Ugh.

- For another art-related 3DS game, Art Academy is decent. I actually quite enjoyed the lessons in the game and they helped me with painting with real media, ironically.

- I dabbled in Artrage for awhile back when I used a Mac, albeit a trial version. It's a decent digital program that emulates real paint.

- For a modern "real media emulation" program, Rebelle 7 fits the bill. It's very good on a technical level, but I personally didn't like it.

- Dotpict is a decent free pixel art editor for mobile.

I've used just about every program I can get my hands on, i see it as a sort of taste test for them!
For programs I have used with any consistency we start with the great mspaint! I use it just about as much as I use clip studio paint and have always for about 10 years now. It's definitely unpopular though not unknown. To be honest I think it's a decently competent program and I actually enjoy its simplicity, helps me focus on the art itself.

Going along with this is Pencil2d an open source animation program that's basically the mspaint equivalent for animation XD !!! You can only animate on an 800 by 600 canvas, if there's pen pressure sensitivity I can't seem to get it to work, and it's got some really basic brush features. I adore it though because it just let's you animate the second you open the program! There are other free alternatives that are far better in many ways, but it's simplicity attracts me yet again.

I own the animation program rough animator, it's a semi-obscure payed animation program. It's on both Ipad AND desktop but you can definitely tell it was mainly programmed for the former. I rarely see it talked about when mentioning programs for animation but I find it pretty good!

Medibang paint is also a lot more niche (at least on desktop) and is a more illustration / manga focused sister program to firealpaca. I did quite a few illustrations and digital paintings in it. Its blending was really nice to be honest.

I loved seeing mentions of Krita, Gimp, and the like because I remember starting my art infancy on those before going to sai, firealpaca, sai2, and more!
