Crashes and…

… also has adverts and apparently no pay option to avoid them. I deleted and re-installed the app 3 times, but each time it either crashed outright or simply didn’t work right. And I couldn’t find the “box” to change color / theme using hex code (even though the app creates a folder in icloud drive with 100+ color / theme choices. I gave it a good try because I liked the idea of different themes and colors. But I finally had to let it go.
