. I .This one is my favourite because of the business to use and a very easy-going user interface. I have been using this wallet for years now and I have gotten the best experience of a mobile wallet. It is an open source for apple mobile devices while the app isn't open for its android version. You get the privilege of saving your private keys by yourself, without nobody knowing about it. I found it very secured because of this very feature. For developers and advance users, it features an open-source and audited code. They have also an exchange services where you purchase coins directly with your debit or credit card. It is powered by kyber and are very reliable. They aallow you purchase some major crypto currency with your credit card directly. Though I am not fund of using them because they place a minimum purchase of about 150$ which has been beyond my power. It has easiness to connect to the dapp browser and other protocols as well as decentralized exchange and so many others. They are my favorite.
