ArtCollection.io alternatives

Terrible experience. I was interested in the service and signed up without knowing the need to have a Zoom call with their VP to use the service (something that wasn't advertised anywhere). I couldn't schedule the call then and left it for later. From then on, I haven't stopped being spammed with emails to "finish my account" and phone calls from them (several emails AND phone calls from NY daily). They have a very aggressive policy of reaching out, which I don't feel comfortable with. I've requested they delete my account, and won't be doing business with them. Won't recommend creating an account with them; there are other alternatives I'll be exploring.

impossible to download from google play. Even if you download apk from legit platform, doesn't work. Tried the 3 proposed methods, nothing is working: "continue with google", "Enter without account" and "create account" : Network error Unable to host "api.magnus.net": No address associated with hostname.
