I think users are trying to find alternatives to make it easier to use mobile apps Uniswap from Google Playstore, but they don't research Uniswap if the official app is not available other than the website version. I will not use any application other than those linked on the website, Twitter and telegram, because if you are using a third party application then you will be ready to face the risk of wallet hacking.
This is why people always remind us to always be careful when we are in the crypto space. Something that looks good doesn't necessarily have good security. The mobile application make it easy for trader to control and observe price movements without having to open the site, but people can still do something in a hurry without trying to see the validity on the official site. Just like you, I have never tried to use a mobile application for trading activities from any exchange.
