RewardMyKiddo

Reward My Kiddo is intuitive and simple to operate!
Parent selects child, task/duration and the reward to be awarded at completion. Child acknowledges executing task on a daily base and Parent gets notified. Upgraded to Premium version (paid version) allows Parent to include multiple tasks per child and multiple kids. Task and reward can be defined by text and/or pictures. If "confirmation" option is enabled, parent is required to approve/reject the task progress - on a daily base.

There are several advantages to giving rewards to kids, including:
Motivation and encouragement, building self-esteem, developing a sense of responsibility, promoting desired behaviors, teaching goal-setting and perseverance, strengthening parent-child relationship, fostering a love for learning and creating a positive environment.

...and did we mention you could just type "Good Deed" as your child daily task? Nothing more than doing good deeds helps your kid to develop kindness, empathy, sense of responsibility and of course have impact on the community (school, neighborhood, etc.).

It is important to note that rewards should be used in moderation and that intrinsic motivation should also be encouraged alongside extrinsic rewards.
