What are some good free software to make logos?
Definitely Photopea, It’s a great alternative for Photoshop and has been a favorite program for some of my friends who do logo designs.
getpaint.net, it can get close to photoshop once you install some plug-ins for it
I hear about it a lot, I’ll try that and see how it goes.
Logos can be created in mostly any needed programs like Gimp - Paint.net - Inkscape, to gather more information you need to develop time into researching things related to finding a specific program that your comfortable using.
In your case, I would try learning Gimp as it’s a easy program to learn how to create UI designs or even simple related logos. You may want to do a quick search around as the question you have in mind can likely be researching and providing you with many results.
There are thousands of tutorials and resources, that will help you along the way consider learning the basic to get the hang of whatever specific program you choose that are user friendly.
