I am new to monero. I'm mining and have a gui wallet on Arch, but I am looking for a good option for iPhone. I am concerned about how to be sure that keys cannot be compromised by a malicious or compromised iPhone app with the phone wallet. I am not sure how you could know for certain that the developer had not built in a backdoor to steal keys without having an open source wallet.
Any feedback on safe wallet selection?
Edit: I see that Cake Wallet says it is open source and I found a repo but the last commit was 2 years ago.
Edit 2: Cake wallet's real repo is up to date [https://github.com/cake-tech/cake\_wallet](https://github.com/cake-tech/cake_wallet)
