Application boot time

#1

Hi everyone,
Recently I have received an order for mobile application with 3 possible choices of technology: Ionic 4, React native and Flutter.

I had really good time in developing Ionic 3 applications so I would choose Ionic 4, but i created sample app and was a little bit disappointed in result.

It takes a little bit more than 2 seconds to show first page and it looks unprofessionally with this first gray screen and then after splash - white screen.
Do you have any advices how to improve this aspect?

PS. I used ionic build --prod and cordova with --prod flag.

Refresh, how fast should ionic 4 app boot?

#3

The gray screen looks like the actual splash screen (which is missing an image maybe?), because the “splash screen” already has a spinner which the real splash screen can’t have. How did you setup that project?

Also post your ionic info output please.

ionic-info

Its just basic ionic tabs app from cli and cordova comands:

ionic cordova prepare android
ionic cordova build android --prod
