Incentive is a free iPhone app developed by Arthur de Rijke that aims to motivate users to complete tasks by gamifying their to-do lists. This unique to-do list app awards users with points when they successfully complete a task. These points can then be used to pick a reward from their wish list, but only if they have accumulated enough points.

The app cleverly encourages users to stay focused on their tasks by making the check mark button to tick off a wish visible only when enough points have been earned. This way, users can set their desired rewards, such as buying a computer game, a new dress, or going to dinner at a specific restaurant, and work towards them with a sense of anticipation.

Incentive also provides two important guidelines to ensure effective use of the app. Firstly, users are advised not to reward themselves before completing the task. This prevents the detachment of the reward from the task, ensuring that the desired outcome is achieved. Secondly, users are encouraged to assign realistic point values to tasks and wishes. Simple tasks like "empty dishwasher" can be assigned a few points (e.g., 5), while more challenging tasks like "paint the house" can be assigned higher points (e.g., 100). Similarly, small wishes like "eat some chocolate" can have a lower point value (e.g., 15), while bigger wishes like "buy a new TV" can have a higher point value (e.g., 1500).

Incentive provides an innovative approach to task management by incorporating gamification and rewards. It offers a unique way to motivate oneself to complete tasks and stay focused on achieving goals. With its user-friendly interface and intuitive features, Incentive is a handy tool for those looking to gamify their to-do lists and boost their productivity.
