Although we do not endorse any wallets, our personal recommendation is Exodus. No account setup is required, and it is the easiest wallet to use. You can download the app for iPhone or Android and have it setup up within a few minutes.
** Once setup, please write down the 12 words on a piece of paper and keep it safe. DO NOT SHARE IT WITH ANYONE! This is your backup phrase and anyone with these 12 words will be able to steal your bitcoin. This backup phrase is used to recover your bitcoin if you happen to delete the app or lose access to your phone. **
