App for Crypto Stock Alerts - Developer should understand stock market and crypto

Hi, So it's a concept similar to stock market alert apps such as Stock Alarm. (which also works for crypto) BUT I noticed with those programs, the user experience is: - THE USER has to find the stock/ coin (crypto) they're interested in and then it can be tracked & alert you when certain parameters are hit. HOWEVER, I'd like: - THE APP to find the stock/ crypto. - And in this case, have the app solely designated for only Crypto (BTC, ETH, and a few hundred of the highest market cap alt coins) - Then instead of the user choosing the stock (well the *coin), the app would alert you ASAP when there's an irregular price shift up or down and/ or if news volume going on for a particular coin. - So I'd like to set up different parameters to trigger the alters, such as: *When the coin jumps up or down 10% in price within 10 minutes or less- the user is notified *When there's an abnormal % gain of tweeets for a certain #CoinName - the user is notified So you'll need to: 1. Integrate a system into the app to check twittter feed for #btc #eth #cardano #xrp etc.. and then when it detects a high volume % gain UP it alerts every user on the app. 2. Integrate coin gecko site into the app because it's very accurate for market changes. And again, when the coin price goes drastically up or down (within as little as a minute or EVEN less), then it alerts every user on app;. Other things to note: * App should malfunction otherwise like a normal stock app, but for the top 500 market cap cyrpto coins: - auto- propagate minute/ hourly/ 12hr/ daily/ weekly/ monthly/ yearly/ max : prices, all time high/ low - show the coins market cap, volume, total supply of coin, total current mined coins - connect via twittter api, showing latest tweeets about the coin - provide an affiliate link to where they can purchase coin Currently, I just want on ios for beta. Should also be able to bill $ people for monthly or yearly membership and include a free 1 week trial. We can decide on billing vis app store or payment processor. That's everything, thanks!
