Terrible!
For such a nice looking UI, Spark is absolutely TERRIBLE! Soooo Sloooow to do any little thing, and it saves every time I think about changing something. Half an hour to reposition a few words on an existing card... Wow, brutal.
There should be an offline editor or something to improve the response time.
Also if a shape is small, I can't move it.
Also, i can't select multiple shapes to re-position.
This app gave me anxiety! (seriously)

Logo pulled from libraries render with artifacts. You guys seriously just need to get the basics down before you keep adding features.

Adobe Spark was great for me until a few months ago when the templates and text just became distorted. I sought help, but support was horrible too. My issues were never resolved, so I have since moved on to Snappa, which works just as well and is as easy to use.

I spend nearly every day on photoshop and in premier. My wife asked for assistance with a project so we tried spark. Heinous isn’t even the word for this app. Don’t use it! You’ll wind up with nothing to show and no hair in the process.

This is a garbage app. I am experiencing the same lag time, lack of flexibility and overall terrible functionality. As soon as I am done with this video, I will find a different platform to utilize.

Agreed - it is awful. I don't know how Adobe can offer it with a straight face.
