Hi, welcome to the forum 
You will be able to find some information on the app.
For example, below is for Vanguard World ETF (VWRL):
Here, you can see the Dividend Yield, TER (Total Expense Ratio), ie fees and a Key Information Document you can download for more info on the ETF.
Or, alternatively, you could always go to the actual Vanguard website for info, eg, again for VWRL: FTSE All-World UCITS ETF - Income (vanguardinvestor.co.uk)
