Is premium required?

I used to always use this app, however one day I accidentally deleted it and so I re-downloaded the app,and I couldn’t get into the app because I did not have premium.
Is there anyway I can get in the app without having to get premium?

P.S. I absolutely love the app, I’ve also recommended the app to many of my friends and family however their having the problem as well.
