I have just added a donation button for if you liked my work and want to donate. :) Donating will not add any extra features. The app will always be free and ad-free as I have promised. Donate amount is set to INR 50, which is around 0.99 USD currently. Thanks in advance. Cheers for the beer.
Note: I have not tested in-app billing as the publisher cannot test it directly without setting a testing account. Please mail me if you face any problems.

Future releases include the following:
Social Network sharing
Notification with an expandable view showing values
Optimizations for minimal battery use.
Widget
Temperature based warning when it crosses a set value.

Please provide feedback.
