The app works perfectly and does exactly what I need it to do for my store. It’s simple to set up, user-friendly, and saves me a ton of time when managing size charts. What really stands out, though, is the support team — they respond quickly, are extremely helpful, and go above and beyond to make sure everything is running smoothly. It’s rare to find such reliable customer service these days, and it makes a huge difference. Highly recommend this app to anyone who needs professional, easy-to-use size charts with top-notch support behind it!

App stopped working, sizing chart doesn't show up anymore after 2 years of using it. Seems like it isn't working anywhere on my stores.

edit: was down for me for a day but is working again, developer reached out and was very nice.

BF Size Chart works very well and the price is certainly worth it. After a theme update that I initiated, some of my custom settings were reverted and I had to reach out for help. I was provided the needed help quickly and the experience was very pleasant and non stressful.

One thing I like about this app is just how simple it really is to use, it doesn't drag down my site and there's not a bunch of useless functions. Simple can be very refreshing.
