Already need a little bit of help with your New Year's Resolution? For today, fitness tracking and run training app Runtastic will let you upgrade your free app to the Pro version for no extra cost. So what are you waiting for?
You can jump into the deals page here to get all the instructions, but it's a pretty simple process. Note that it will only work for Android, however.
All you have to do is install the app from Google Play (or just open it if you've got the free version), go into settings, then scroll all the way down to select 'Runtastic'. In that menu click 'Enter Promotion Code' and use 'APPOFTHEDAY' to unlock your pro version. Happy running!
