Crypto Coin Check is a free Android application developed by David Pertiller that provides a broad insight into the cryptocurrency markets. The app supports a wide range of cryptocurrencies, including Bitcoin, Ethereum, Ripple, Cardano, Solana, Litecoin, Stellar, Bitcoin Cash, EOS, IOTA, Dash, and more. It offers real-time visualization of current rates, price history of the last 30 days, and real-time price comparison across exchanges.

One of the most interesting features of Crypto Coin Check is the calculation of the arbitrage potential, which is the price difference between exchanges used for risk-free high-frequency trading. The app also supports the comparison of prices across exchanges, including Coinbase, Kraken, Binance, KuCoin Poloniex, OKX, HitBTC, Bitfinex, Bitstamp, Coinbase Pro, Bitpanda, and more. The dashboard is easy to use, and the app provides a clear visualization of the currently cheapest and most expensive exchanges for buying/selling crypto.
