Cryptinfoalarm free app to control the cryptocurrencies.
You can set alarms between 2 currencies (ex.: Bitcoin/Ethereum) and the limit you want to set (ex.: 10%) to increase or decrease (upper or lower limit) and the app will rings when this ratio has reached. When it happens you only need to go to your wallet to make the exchange to earn money, day by day.
You can see the actual currencies values too.
I hope you like it and earn big money !!
