Should I still download it?

Hi, I've seen the recent vid on the channel about apps in 2025. One of them is "Comatose" I wanted to download it but my phone said it is malware. Is there anyway I can check if it is true or false, so I can decide if I want to download it or not. Thanks in advance for your help! :)
