Using a weekly schedule or tracker to check off obligatory and Sunnah prayers is considered an innovation (bid'ah). Such methods were never practiced by the Prophet Muhammad ﷺ or his companions, and relying on them risks stripping worship of true devotion by turning it into a mechanical routine. Muslims are advised to worship with sincere energy and adapt to their daily circumstances rather than forcing rigid, unprescribed accountability charts.
Furthermore, a person might be presented with an action that is originally less virtuous, but it becomes more virtuous in his specific situation for a reason.
For example, if he is occupied with honoring a guest who has come to him rather than praying the regular Sunnah of Dhuhr, his being occupied with that guest is better than the Sunnah prayer.
I advise our youth against using these methods to stimulate worship, because the Prophet (ﷺ) warned against such things when he urged the following of his Sunnah and the Sunnah of the Rightly-Guided Caliphs, and warned against innovations (bid'ah), explaining that every innovation is misguidance—even if its innovators consider it to be good.
There was nothing like this in his guidance, nor in the guidance of his Caliphs and Companions (may Allah be pleased with them).
