Currently, Coinmama does not have an app. So, users who wish to buy/sell cryptocurrencies can do so directly from their website. To transact, you have to have an account with Coinmama. To create one, click on sign-up, enter your personal information, verify your email, upload your id documents, take a pic of yourself along with the id and a note stating ‘Coinmama and the date,’ and upload them again.
