Back in 2011 when I co-developed Battery Notifier BT Free (Battery Notifier Big Text at the time) and Battery Notifier Pro BT with my programming partner Dmytro Shkil, there was only one app with the name Battery Notifier which was created by my partner. Now there seems to be all kinds of copycats. To be certain you have the original apps, with no ads, only download them from Google Play and make sure the developer is Shkil/larryvgs.
Also, please be aware that Google Play is the only place authorized to carry our apps
If you installed an apk with our name from some other site and are getting popups or ads,
the app has been altered and might have malware
