SteemDBM is an android application to display the VOTING POWER and BANDWITH REMAINING of a steemit account.
To make the application better. I would add a notification system in the next version. You will have the possibility to activate notifications in order to know in real time when someone Upvote you.
The application is developed on the web (css, js, html) with cordova.
The central server that will allow registration to the notification is developed in Nodejs with Express. I'm using node-localdb to record the user/gcmToken pairs.
For notifications I use Firebase with the lib: https://github.com/arnesson/cordova-plugin-firebase
