I use Mypaint since many years, for graphic palets worskhops with children , and I have just positive feelings about it. Many tools, rather easy to use, and great compatibility with my Wacom. Recommanded.
Fiji might be a bit more popular than MyPaint. We know about 6 links to it since March 2021 and only 6 links to MyPaint. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Mypaint is the most lightweight software ive used, but it doesnt have the same level of community support as krita, so some features may be lacking... Source: over 1 year ago
Essentially, I've found the more time you have to spend spend learning the apps and/or using its tools, the less time you have to actually enjoy the art of creating. Try apps that cut down the friction between you and your art; Krita, MyPaint, etc. Would be my first suggestions since they're free, then maybe ArtRage, or Sketchbook Pro if money is not a concern.

Note: The .gpl format is also supported by Aseprite, Drawpile, Krita and MyPaint. - Source: dev.to / almost 2 years ago
Mypaint (http://mypaint.org/) is simpler to use than Krita. Krita can be 'simplified' a bit by closing some of the unnecessary docked tools on the right. Source: about 2 years ago
Take a look at MyPaint or look here to see if something tickles your fancy. Source: over 2 years ago
I think you're looking for ImageJ. The "GUI" version is Fiji which I can't recommend enough. I use it to measure distances in photos based on reference objects but I think its origin is from scientific image processing. Source: about 1 year ago
If you are using the FIJI distribution of ImageJ (https://fiji.sc), then you should be able to drag the .mvd2 file onto the FIJI toolbar, and it will open using the Bioformats Importer. You need to have the .mvd2 file and the Data folder that is associated with it in the same folder. If you don't have that data directory, the .mvd2 file is useless AFAIK. Source: about 2 years ago
FWIW, depending on what you need it for, there's a variation called FIJI, which is.. "Fiji is just ImageJ"(but with a bunch of plugins). That is, one-click install to get a ton of commonly used things, though many are aimed at biology. Source: about 2 years ago
FiJi is ImageJ plus a bunch of useful plugins. My favorite is BioFormats, which reads a whole bunch of proprietary image formats from microscope software etc. Easy to download and install, too -- you can get it here: https://fiji.sc/. Source: about 2 years ago
Looks a whole lot like the Fiji ImageJ logo: https://fiji.sc. Source: over 2 years ago
