Signed up for a "7-day free trial - No credit card needed" with an existing email, clicked "start" to create a stack only to have nothing happen. Tried creating a "quick note" only to be stopped because I had to select a stack to put it into. Couldn't create one. Advice for the devs: get someone to use the app that hasn't before and make it for them. Also, not sure what you charge after the free trial period. Whatever it is, you shouldn't be charging it with this level of quality.

Thanks for your feedback! 1) When you create the Stack it appeared lower in the list so that's why you probably thought nothing happened. 2) When you click Quick Note there was already the blank Stack available to save to, but agree it might not have been intuitive enough! We'll make sure to review this workflow and make it a better experience! :-)

I just started using it today, so everything I'll write now is based on my first impressions. # interface is Not at all user friendly # I'm trying to find 'rearrange cards' option for last 30mins. # Help is not easily accessible # Help page is not adequate with info # interface icons are not easily identifiable # glitches are there (phone app)

Wanted to like this app, but cannot get past page 1 of 4 on the welcome screen. Not very welcoming.
