Hey, i recommend you try a new price alerts service for Facebook Messenger
it has percentage and units change price alerts for
Bittrex, Bitstamp, Poloniex, Kraken and CoinMarketCap
https://www.kryptolabs.io/Been using it for a while looks really nice, great way to see how price is different everywhere
sometimes almost by 500
I think this post should be in service discussion section or service section. Find below the moved this topic then click or choose "service or service discussion".
Anyway, is this available in apps store and google play?
