J'avais un petit soucis d'affichage, support très réactif et problème résolu dans les 10 minutes qui ont suivi l'envoi du mail. Je recommande avant que l'appli devienne payante.

Updated review: They quickly fixed the problem. User error I'm told. I didn't enter a code for a change in theme.

Good morning,
Sorry for the inconvenience, we checked your store and there is no app initialization code in your theme. This is a problem caused by you not initializing the new theme.
We have helped you initialize the new theme, the problem has been solved, and everything is working fine.
If you need to change the theme again, you need to click on the left navigation "Installation" in the app background to initialize the new theme before it can be used normally.

Awesome app, extremely easy to use, great customer support. It allows me to make it easier for my customers to add their measurements for the custom clothing I make!

Works better than the paid apps of the same category. The developer was also extremely quick and helpful with an issue I had. Had it resolved for me in no time!

This app is amazing, it has every feature I was looking for, great customisation features and very easy to use. The service is incredible as well, I had a slight issue with compatibility with my theme and they literally got back to me within 5 minutes of me sending an email and fixed the issue for me straight away. I tried out a few different variant option apps and this was easily the best. Highly recommended!

Really easy to use, especially for stores like ours with a large variety of items with different customisation options. Smart feature of allowing templates that are linked which can be applied across different products. Appreciate it being a free app and hope it stays that way!
