Voyager

Voyager is a cryptocurrency broker that has recently become one of my favorite apps to use for trading crypto, the platform connects multiple exchanges together to route orders behind the scenes while providing users with commission-free trading and offers competitive interest rates on various cryptocurrencies.

Currently the app is only available in the US (except New York) but they will soon be expanding to Europe and Canada. Voyager is also launching a debit card with cashback rewards and will soon be releasing a desktop version of the app.
