For me personally I did try a lot of these habit trackers and notetaking systems and none of them quite worked for me so I just decided to build something that's very specific to how I like things. I didn't just build a habit tracker or whatever just for the sake of building another one, I built one that specifically suits my needs.

Usually what happens is a lot of other people in the world also feel the same way as me and if they like how I have approached the app then they would download it and use it and I think that's how you get a lot of different types of habit trackers coming up all the time
