DefiPlaza does not have a mobile app (yet), but you can still swap, stake or add/remove liquidity on your mobile phone or tablet.
To interact with DefiPlaza you need to install a mobile version of Metamask. You can sync your MetaMask extension wallet with mobile by using the MetaMask Mobile Sync feature. You can read how to do that in Metamask’s FAQ.
Within Metamask you then go the browser and navigate to DefiPlaza.
