Opal can be improved in some ways. In the paid version, there are multiple features, but in the freemium version, there are fewer features. The blockage of the application can be more rigorous. Right now, if we play two to three games, then a math game or anything, we are able to remove that lock. It should be more rigorous in some manner, and for some applications, it should be more rigorous. Application-wise rigorousness should be introduced. The different modes are good, but they should be more customizable according to the person. The end goal should meet whatever the objective is, so if the person has used more than six hours, then it should remind the person frequently that this application has used this time and this is an application you should not use. It should give us a timer or some kind of notification that the person will not use it anymore.
