I remember using this app on my android phone to make some mind maps a few years ago. It's a free app and mostly it worked fine, easy to use, you were able to use it on a tablet or on a phone, it wasn't slow, it let you customize the map a little bit. So in general was a good experience, no issues and mostly, it helped me to finish the mind maps easily and fast. Review collected by and hosted on G2.com.
The app had a good performance and never had issues with it, but the only thing that I disliked about simplemind is that the design seems to be stuck in the 2000's, it was hard to make it look modern or different, this didn't affect the result but it was and it is a thing that I always pay attention to, the option to modify your designs to make them look cooler.
