Hotspot Notifier is designed to search nearby Bluetooth and Bluetooth Low Energy devices.
When one of the devices you selected is in range, this app will notify you so you can start an Hotspot.
NOTE FOR VoLTE - ENABLED PHONES
Using this app to provide an Hotspot to a VoLTE-enabled phone can strongly improve its battery life, since the connection to the carrier's base station will be handled by the device who creates the hotspot (like a tablet for example), so the phone has to amplify a signal much closer and clearer, saving around 20% of battery life on a full charge(can be more or can be less, depending on the coverage and the signal quality in your area).
NOTE FOR LTE TABLET USERS AND 3G PHONE USERS
Using this app, you can enjoy the speed of the LTE network on your 3G phone, since the top speed of LTE is lower than the speed of the WiFi N (IEEE 802.11n) hotspot created from the tablet.
This app is FREE, if you want to contribute please check BTKeyFinder.
80% of the profit from that app will go to a research project for the deafblind.
Side note: if you own a tablet that supports USB OTG, you can buy a cable like this
that can let your tablet act as an external battery for your phone.
