I found this deal by coincidence as AS not always send me an email about new deals. I look from time to time. OK, let's get to the point.
I opened Crello and Canva next to each other. I found that both are very similar. However:
Canvas UI/UX is a bit cleaner IMO.
Crello has more nice basic designs to start with
Canva has gradient backgrounds to choose from
Crello's text resize function is a little bit painful but manageable.

I also use Adobe Spark, which I'm happy to replace with Crello because of design choice.
I found also important features missing when it comes to editing. When I start to edit on my iPhone and then I want to continue on laptop or desktop, it is impossible. It says that it can be only edited on the phone. I was so surprised. Adobe Spark in this case is super flexible. Why would Crello limit such a feature?
TEAMS;
As a team member one has access to everything and is allowed to edit. However, when a team member wants to change picture or anything else that is for Pro users it shows that the member can do so for 14 days until trial ends. What's the point to have a team if they will be soon limited to what they want to do? Maybe I misunderstand something., so please correct me.
Besides, a team member cannot download ready design. The only Owner is allowed to do so. I guess that only the owner will be able to change the design when something for only Pro subscribers is to be used.
Animation:
I like the feature, but it would be nice to have more than left, right, zoom. Also, control speed.
Stock Photos
Many of us probably have Depositphotos account as they were here too. It would be convienient if Crello integrate in some point with them so instead of purchase I would be able to log in to my DP account and download it.

I give 5 stars because overall I like it and I'm happy with the purchase. I do believe that Crello will evolve further and add or improve some features.
