I'm not a native so my english may not be perfect ;p
So ... i am a student on neuroscience and i have to make an android (and apple if is it possible) app that remind people to take a deep breathe every hour. To do that i need my app to send a notification or even better to launch itself every 60 minutes (on regular day), then show a picture and send a feedback to a server.
I can easily handle the image part and the send small data part.
To be more specific : i need to know (factually) how send notification even when the app is close or even better i need to do a clock alarm like app.
I've seen that some (relatively) expensive pluggin already exist with phone gap... i am ready to buy one if it can help me, but with no complete tutorial it will be pointless.
This one seems interesting but i don't understand that much how it work :
Thank you for any constructive help !
