Use APKPure App
Get Hot - o - Meter (Ad Supported) old version APK for Android
Can an app be used as a cell phone based pickup line?
Move your finger left / right on the screen to control the meter. Use it wisely and it may put a smile on someones face ;)
Use this on your girlfriend, boyfriend, wife, husband to give them a smile and let them know what you think of them.
This can also be a better ice breaker then a cheesy pick up line.
