First… I would recommend you don’t post your email here… No other users here can do anything with it to help your account… but spam you… yes, that can happen 
I don’t know if a iPhone 4 can even run Blynk properly? My 4s with 9.3.5 is painfully slow as it is.
NOPE. Sorry, but the App store page for Blynk shows you need iOS 9.0+ I am surprised you could even attempt to install it.
Yes i lose to much time to install
