Ein's Cuteness Lab
The concept of this app is good. However, it's not compatible with my theme at all. There are so many issues (like weird positioning, weird blank spaces, blocking my menu when scrolling down...) once I installed it. What really disappointed and annoyed me was that the team made me think they would help me to fix the issues at first, and they made me wait about a week, and they told me they couldn't help unless I go edit my code to delete something myself (it was super unclear on what they wanted me to do and I just felt they didn't want to help anymore). What a waste of time. Worst customer service.
