IMHO, the website is better than any app. You get the full functionality of Mastodon, and the site is coded to display really well as a mobile webpage. I tried using like 3 different apps, not liking any of them. Why? Because I've been trained to assume the mobile webpage is dogshit.
Then I finally had the notion "what if I look at a mobile webpage?" IT'S REALLY GOOD.
