I can only think of one app for that, Trust Wallet. Though only available as mobile version, it's open-source and community-driven (at least that's what they brag about themselves).
Trustwallet used to be an open-source wallet, but now it's close-source and they lie about that.
Click
here to see their (outdated) source code on Github. It has been four years since their last update.
Claiming being open-source while trustwallet is close-source is surely a red flag.
