I need an apk so its easier to install in other phones
The thing is, I just need to create one for now and install it on an android of family, could Blynk export APKs? Or a webservice that can empack it into an apk? Can i create an app and call /retrieve data from servers using the auth token?.
In case of using the blynk SDK, do i need to pay something in blynk to create an app to connect to your servers?
You can download APK from google play.
Dear Dmitry, thanks for your fast reply.
I’m meaning, after developing a board on the android app, could i export it as an APK ? or make myself an app with blynk servers data?
yes you can create apks with blynk, but it is not cheap. i’d rather try sharing a project, if you want to control one duino with multiple phones. Or cloning a project if you want to control multiple arduino’s 
Thank you
