UX and UI?
As a busy mom that travels to SF for work 2 hours to and back. I wanted to find an app that was easy to make lo-Fidelity wireframes... low and behold, I found Marvel https://marvelapp.com/
Wow.... and I will say it again wow. This is little app holds a huge punch. I am able to import pictures or actually to draw out my idea (UI/UX) style. Even if I have a silly idea such as a yellow bear with green ears that will pop bubbles and say "my butt just burb"... per my four year old son.
If you have time try out this out app!
