Flip is a free Android app developed by Flip Company in the category of Business & Productivity, specifically in the field of Finance. With Flip, users can easily send, buy, and sell Bitcoin, Dogecoin, and Dingocoin using just the cellphone number of the recipient.

One of the standout features of Flip is its non-custodial nature. When using the app, a new private key is generated that is only accessible to the user. This ensures the security and privacy of the transactions.

The app allows users to fund their wallets directly from the Flip app using a credit card, making it convenient and hassle-free. It supports three popular cryptocurrencies - Bitcoin, Dogecoin, and Dingocoin, giving users a wide range of options for their transactions.

Flip is completely free to use, with no charges for the app itself. However, users will still need to pay the standard blockchain transfer fees for their transactions.

An interesting feature of Flip is the ability to send coins to any cellphone number, even if the recipient does not have the app installed. In such cases, the receiver will be notified via SMS and provided with a link to download the app. This makes it easy to send coins to anyone, regardless of whether they are familiar with cryptocurrency or not.
