Keepur lets you give or take away points from people.
You can give points after fact -- "Thank you honey for the (surprise) flowers, +50"
Or, you can set a (gentle) nudge, assign a value, and let the person(s) claim the points every time the task is done -- "Please load the dishwasher, +10, everyday"
FAQs --
Q. What can I do with the points (received)?
A. Thats entirely up to you and the person(s) you are communicating with
Q. Are the points zero-sum? If I give away points, does it deduct from mine?
A. No. Assume there are infinite points in the universe, both positive and negative. Give (and take away) freely
Q. How does nudging work?
A. Example: Mom sets a daily nudge that says "Pick up your room, +10". Kid gets a reminder (on a daily basis), where he can say "Done" and claim the 10 points; or say "OK", (read as "whateves"), and dismiss the notification -- not unlike the typical parent-teen interaction
Q. Whats with the color coding?
A. Green - Good. Red - Not so good. You want to be in the green zone. And yes, everybody in a group can be green, though most likely in different shades.
Q. Errrhhh...Why?
A1. Good communication leads to better relationships. Its about providing instant, contextual and quantified feedback (and/or encouragement)
A2. Studies have shown that habits are best formed through consistent and repetitive reinforcement. (And yes, positive reinforcement works better than otherwise.)
A3. No more back & forth over "I did this, and you didnt do that..." -- keep track of all the times youve done dishes, and present her/him with data
