Frustrating

Almost impossible to figure out how to use this app. Combine that with there being NO YouTube videos related to the app and you’re entering total waste-of-time territory. Come on folks. Revamp this app. Make it just slightly intuitive. Can’t be that hard!!!

Awesome resource!

I’d forgotten I had this. Not a good thing to forget as this is a HUGE solution to a headache problem all sewists and embroiderers face. I can’t say enough good things about

Impossible to add collection, they want to sell thread

You can add a whole collection. Impossible to add single threads you have. Impossible to work. They seem to have influencers on sites raving about an awful product. You will spend hours and get nothing.

I don’t get it

I bought this app thinking that it would help me select colors for embroidery designs. I want to be able to add the recommended color from a design and find a match in thread colors I have. I guess I just don’t get it. I’ve worked with this app for several hours already, and I can’t get it to do what I want. Maybe it’s not designed to do that.

Great app for managing thread

Easy download and app to use. I now have all my thread inventory— different vendors, ThreadBook types in the app. I love it. I have tried excel, marking up paper ThreadBook charts etc. this is a dream come true!
