Anyone have a step counter type app that will send notifications if you aren't moving or reaching xx% of your goal each day? I have step counters that work ok (Pedometer++, etc.) but I could definitely use some nagging to get up and walk around during the day. Ideally, something that would yell at me at noon if I haven't done 50% of my steps or at 7 pm if I haven't done 80-100%. Thoughts anyone?
