### 5/5 — Outstanding app for thread organization!

*2026-06-24*

I’ve never felt compelled to leave an app review before, but ThreadBook deserves one. This is by far the most complete and useful app I’ve found for organizing embroidery, sewing, and quilting thread collections.

The thread matching feature alone is incredibly valuable, but what really sets ThreadBook apart is the ability to manage inventory, keep track of colors, and even add custom thread names. It has made organizing my large thread collection so much easier and more efficient.

I also greatly appreciate the pricing model. Paying a reasonable one-time fee instead of yet another subscription is refreshing. No recurring charges, no constant upselling—just a well-designed app that does exactly what it promises.

What impresses me most is the developer’s continued commitment to improving the app. New thread lines and useful features are added regularly, making an already excellent app even better.

If you work with embroidery, sewing, or quilting threads, ThreadBook is an invaluable tool. Highly recommended! ⭐⭐⭐⭐⭐

### 5/5 — Love this app

*2026-06-17*

I was having a hard time finding a program that would convert Embroidex thread to other brands, I couldn’t even find a color chart for the Embroidex thread to download. I came across a mention of this app said it wasn’t free, but I thought I would give it a try. It is worth every penny! It has every brand available, every thread I chose to convert to another brand it has found the closet match, I was wishing that I could go in and change the colors, because the company’s colors aren’t very accurate and found that I can. I can actually take pictures of the thread for an accurate color. Love, love, love this app. Thank you.

### 1/5 — Frustrating

*2026-02-25, version 3.0.5*

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!!!

### 5/5 — Awesome resource!

*2025-11-21, version 3.0.4*

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

### 1/5 — Impossible to add collection, they want to sell thread

*2025-10-10, version 3.0.4*

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.

### 3/5 — I don’t get it

*2025-06-04*

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.

### 5/5 — Great app for managing thread

*2025-05-17, version 3.0.3*

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!

### 5/5 — Excellent app and customer service!

*2025-05-17*

Thread Book has been so helpful keeping up with the plethora of thread I’ve accumulated not only from regular shopping,  but from estate sales as well.  I recently noticed the iPad app was not showing the multiple spools when I had recorded more than one spool. I contacted customer service and within an hour Jim responded and fixed the issue with the latest update.

### 5/5 — Excellent App

*2025-03-01, version 3.0*

Excellent app to have for inventory and conversions amongst a lot more!

### 1/5 — App keeps crashing every time I try to open it.

*2024-11-27*

Since April 2024 the app constantly crashes every time I try to open it. I have tried removing and reinstalling the app without deleting my data and it didn’t help. I sent a message to the developer but haven’t had any response.  I don’t want to have to re-enter all my data.  I loved this app but it’s useless to me at the moment. Please help
