Coinflash is an app which lets you maintain a healthy saving habit by rounding off the amounts of purchases and automatically investing the spare change in cryptocurrencies, Bitcoin or Ethereum. Coinflash can read transactional data from multiple connected savings accounts or credit cards (limited to a single bank).
While Coinflash invests money directly from bank accounts, it cannot do so using a credit card without your permission. Further, the app claims that it doesn't store any information more two months after the transaction. In order to keep track of your investments, you'll need to download the Coinbase app on your smartphone. For the service, the app charges $1 monthly from your Coinbase account.
