Bounty, a free app on the Google Play Store, rewards you for checking in at partner places. Every time you walk into restaurants or cafes the app has partnered with, you win points (read vouchers from Flipkart, Amazon or other recharge gifts).
The app works even if you're offline. The 5.5Mb app was recently updated for efficiency.
Bounty works right now only in Bengaluru, Chennai and Hyderabad.
