Newr

4/10 Wouldn't recommend paying for it and the free plan is pretty useless unless you have a very small catalog. It works as expected until you hit the limit, which is very low considering it counts more than just new products towards your usage AND seems to count each new product twice. Unlimited is $20/mo which is steep considering you can do the same free with shopify flow. Unlimited at $5/mo would be fair IMO. Plus side is you only have to add the collection to the site and the app does the rest (until you go over your limit and need to go fix everything manually)

Newr will add the text "NEW IN" on all of your images even when they are used in another collection on your site. There is no option to change or not have this text added to images. An absolute deal breaker. Have contacted support but will be cancelling if this cannot be turned off completely.
