coinalert.live is a decent app, but there are a number of drawbacks, the app itself is extremely slow to load. I switched to FinTab, the connection to the server is much faster.
In particular, I have personally heard many positive reviews about the application from FinTab, please share a link to their website or their topic on the forum
I see that the project FinTab is gaining in popularity, that's good, because a mobile application which helps to quickly and efficiently create a portfolio will always use the demand.
