Be careful of bounty campaigns with "download app" requirement
I am not discouraging hunters to join bounty campaigns that requires you to download their app or wallet. This is just a friendly reminder to everyone that we should be careful since there have been some malicious apps used to collect personal information and steal funds from mobile/pc. There were also instances where hackers were able to exploit the vulnerabilities of some apps.
If you still wish to continue and download their app, at least take some measures like not storing your private keys/seed phrase in your phone/pc to protect your funds.
Have a safe bounty hunting!
