YOShInOn, my RSS reader, started out with an in-your-face ugly design, I switched it over to use Bootstrap (use it at work) and now it looks very conventional.
Right now I am the only user but I have been demoing it. Right now I have no idea if this is going to stay my own app, be open sourced, or become a SAAS product.
I was kinda proud of it being an ugly duckling (yellow and all!) but the way I was developing the code (maybe a week of heavy work, three weeks away) meant I would forget how my custom CSS worked so I wasn't being very coherent.
I use reactstrap at work so bootstrap concepts are frequently on my mind and using plain CSS bootstrap deepens my understanding. A consequence of this is that YOShInOn looks very conventional, it doesn't stand out as really ugly or really pretty and that's fine because the workflow and the algorithms inside are the star of this show.
