The features seem to be good, only for ios though. BTW, you should note that this is a paid app of $6.99 per month if the user wants to have an alert for several currencies.
That is correct. The free version allows the user to add / edit / remove one alert that can be used to track an indefinite number of changes to the respective pair. The paid version removes ads, enables more arbitrage options to maximise profit across different currencies, enables more emails to be added and features a special dark theme.
I'd like to see an option where I can select how much money I would like to make per arbitrage opportunity. Let's say I'd like to sell BTC on Kraken for 9000 EUR and then buy on Bitstamp for 8900 EUR. I'd like to be alerted once this price gap exists between the 2 exchanges. Is that possible?
Arbitrage alerts are on the TO-DO list for the following updates.
